Price, C. "Investigating footwear biomechanics concepts in 'health and well-being' footwear." Thesis, University of Salford, 2014. http://usir.salford.ac.uk/32920/.
Full textAbstract:
Health and well-being’ footwear positions itself in the footwear market between high street footwear and specialist therapeutic footwear. Manufacturers in this footwear category promote benefits when compared with standard footwear. However, the full exploration and validation of such proposed benefits requires scientific exploration through the application of footwear biomechanics concepts and techniques. The studies herein were undertaken to assess these biomechanical concepts in ‘health and well-being’ footwear, particularly in FitFlopTM footwear. The studies are experimental studies with repeated measures designs. A total of 128 individual participants volunteered, 28 of which were included in two publications. Variables were quantified using an in-shoe plantar pressure measurement system (with a bespoke insole), electromyography, 3D motion capture, force plates, accelerometers, a modified questionnaire and a custom-made mechanical drop-test device. The research identified that ‘health and well-being’ footwear can be manipulated to increase shock absorption, namely reducing the heel-strike transient magnitude (-19%) compared with a flip-flop. ‘Health and well-being’ footwear does induce instability at specific phases of the gait cycle, which is specific to the outsole shape of the footwear. For example the MBT shoe increased muscle activity relating to controlling sagittal plane motion. The biomechanics of gait are also altered compared to standard footwear styles, such as reducing the frontal plane motion of the foot in stance (-19%) and the magnitude (-86%) and duration (-98%) of gripping with the Hallux in swing compared with a flip-flop. The tested ‘health and well-being’ footwear was subjectively rated equally as comfortable as a control shoe with increased regional pressures in the midfoot (≈25%) and decreased peak pressures in the heel (-22%). Therefore ‘health and well-being’ footwear may influence the biomechanics of wearers however further exploration of meaningful differences and individual population differences is required. The studies emphasise the importance and relevance of testing walking, as well as running, footwear to the wider footwear biomechanics field and demonstrate how this may be integrated into research and development processes within a footwear company.

The design of Expressive Footwear centered on creating as dense a sensing module as possible. Originally, the motivation came from creating a dance performance in which the dancer is participating directly in the creation of music in the dance performance. In order to accomplish this, a wide variety of sensors and sensing techniques are used to quantify physical parameters of the foot. Once the sensing is accomplished, the resultant data is transformed to music in real time. Recent work has also included using Expressive Footwear in gesture recognition. The development of this system and each of its parts is elaborated upon in this thesis.

Full textAbstract:
A need to reduce the number of design iterations, coupled with a requirement to reduce the weight of the new generation of TPU running shoes has lead to the use of finite element analysis (FE) within the athletic shoe industry. The collaborators in this research, adidas, were already using the technology, but only on individual parts, and on a reverse engineered basis. This thesis presents a thorough review into the materials used in athletic footwear, their application within running shoes and the methods of testing non-linear, highly deformable polymers and polymer foams. The fundamentals of the FE process are examined, along with a discussion of the current testing methods for shoes. The novelty in this work comes mainly from the comprehensive, logical progression through the modelling process as applied to this new area. Sample materials were tested, revealing new test methods. These were then analysed and converted for use in ABAQUS v6.5 which was the FE software used. The modelling of the sample materials, their tests, then shoe parts and midsole assemblies are discussed at length. At each stage the required complexities were added to the model, and these are detailed. This includes the import, conversion and repair of highly complex geometry, meshing techniques for this geometry, methods of building models of shoe assemblies and all relevant issues that arose from these processes. In addition, a shoe with an internal mechanism was modelled to assist in the design process. The effect of damage to shoe materials was also studied. Physical tests were carried out to verify all the FE models, and the results are presented. In addition, shoes taken from the end of the production line with the uppers attached were tested in order to compare the change in performance between the component parts and a finished product. The results of the modelling showed that was possible to construct and run full shoe assembliesw ithin a reasonablet ime. Fair prediction of the physical responseo f the assemblies was seen using material data taken directly from the sample data, but a method of correcting the initial error in the material test is presented which gives very good force/deflection results in TPU parts. A method of adjusting the entire assembly's material models is then presented, which improves the initial verification. In addition to force/deflection readings, digital image processing was used to monitor the structural response of the shoe during loading, and a set of structural metrics is put forward. The results of these indicated that while the shoe models were representing the cushioning response well, the shape of the shoe was not replicated, suggesting that the model in its present state would be unsuitable for use in some forms of test. Suggestions for improvement are made. Comparison of the structural metrics between shoe assemblies and production shoes suggests the possibility of a quantifiable metric for what would be considered a 'good' shoe. The repercussions of this are discussed in the conclusions.

Pisani, R. "Footwear and soft ground interaction." Thesis, University of Salford, 2002. http://usir.salford.ac.uk/2170/.
Full textAbstract:
The aim of the research reported in this thesis was to improve the understanding of footwear and soft ground interaction and, in particular, its mathematical modelling. The work was undertaken for the Military Footwear Section of the MOD's Defence Clothing and Textiles Agency (DCTA) who funded the research in conjunction with the Engineering and Physical Sciences Research Council (EPSERC). Although research has been carried out on the interaction of footwear on firm surfaces, minimal work has previously been carried out on softer surfaces often encountered in combat situations and little effort has been applied to its mathematical modelling. The research programme included the development of mathematical models using soil mechanics theory, and experimental work using a soft-ground slip-rig. The prototype soft-ground footwear slip-rig that has been developed is a manually operated device based on simple mechanical mechanisms using weights and pulleys. The rig enables the measurement of traction and sinkage for different soil types, sole materials and tread geometry, at various angles of heel contact and applied vertical load. All experimental work has been carried out with the use of scaled up cleats to obtain measurable results. An investigation into three dimensional end effects has determined at what cleat length the problem becomes two dimensional. The experimental results have shown the effects of cleat geometry on total cleat traction for sand, and in particular the geometric characteristics that promote and reduce traction. These results have been analysed using Taguchi's Analysis of Variance technique. Traction distribution experiments have determined the proportion of traction obtained from different cleat areas. Soil mechanics theory, and in particular Coulomb's retaining wall theory, has been applied in the theoretical modelling of footwear and soft ground interaction. A two dimensional total traction model has been developed using MATLAB software and experimental and theoretical results have been compared. The traction versus cleat geometry trends for both the experimental and theoretical results were in good agreement.

Full textAbstract:
A third of over 65s have at least one fall per year whilst a quarter of over 45s endure foot pain. Footwear is associated with both fall risk and foot pain hence its investigation is of great importance. This thesis explores the potential benefits of minimalist footwear for the older adult population. Chapter 2 ascertained the kinematic and kinetic differences between walking barefoot versus in footwear whilst highlighting the limited research on minimalist footwear, older adults and muscle activity differences. Accordingly, Chapter 3 outlined that minimalist footwear is kinematically more similar to barefoot, irrespective of age, thus offering a viable alternative. Similarly, Chapter 4 showed walking in minimalist footwear and walking unshod exhibit similar lower leg muscle activation patterns whilst differences exist to conventional footwear. Chapter 6 demonstrated how increasing intrinsic foot strength improved functional and static balance whilst Chapter 7 showed promise for minimalist footwear improving foot strength, functional balance, balance confidence as well as reducing foot and joint pain in a sample of older adults. In conclusion, this thesis highlights the need for future work to continue to investigate minimalist footwear in both older adults and other age groups for benefits to stability, foot health and joint pain.

Sampson, Ellen. "Worn : footwear, attachment and affective experience." Thesis, Royal College of Art, 2016. http://researchonline.rca.ac.uk/1811/.
Full textAbstract:
This research by practice explores our relationship with and attachment to shoes. Focusing upon the shoe as an everyday object, and on the embodied experience of wearing, it examines how through touch and use we become entangled with the things we wear. Drawing on anthropological and psychoanalytic perspectives on attachment, affect and the self, it asks: How can the act of wearing create attachment between the wearer and the worn? What is our relationship with the used and empty shoe – the shoe without the body, the shoe no longer worn? It suggests that our particular relationship to footwear is located in our intimate and tactile relationship to it; that touch and duration of wear create attachment. This research suggests that through use and wear shoes become, not only a record of the wearer’s lived experience, but also an extended part of them - a distributed aspect of the self. That the affective power of the worn shoe is a result of this intermingling, the cleaving of garment and self. Despite a growing body of research on footwear, the worn and the used shoe is absent from much of fashion research. The shoe tends to be interpreted as a symbolic, metaphorical, or imaginary artefact; its material qualities and the embodied experience of wearing the shoe are seldom referred to. This research seeks to place the artefact, the shoe, at its centre. Through an iterative process of making, wear, and observation, it aims to make apparent the intimacies of our relationship with shoes. Rather than record the narratives which we apply to footwear, it seeks to highlight the material traces of these relationships: to present the ways they are embodied within the artefacts themselves. This research is research through practice, into the nature of our relationships with shoes, through making artefacts and images (installation, film and photographs). It is material culture research enacted through the production of artefacts. It situates itself as art practice; the shoes produced are not footwear in a conventional sense but instead are objects designed to amplify and make explicit their role as records of gesture and experience. These empty shoes are records of an absent performance, of gestures which are lost to the viewer, so that only their traces, the marks upon the shoe, remain.

Full textAbstract:
Use of appropriate footwear among diabetics and those with diabetic foot problems has been well documented to play a vital role in the prevention and treatment of established foot disease. The incidence and prevalence rates of diabetes in Africa are increasing and foot complications are rising parallel. Nigeria is Africa’s most populous nation which also has the highest number of people (up to 3 million) suffering with diabetes in the continent. This is related to the lifestyle of the people which is changing including diet. Many urbanites are embracing Western way of living. There is however lack of adequate knowledge about the role of footwear in the management of foot related problems among diabetic patients in the country. This study is the first of its kind to be done in Nigeria with an aim to develop a framework that would help to identify appropriate footwear materials and designs for people suffering with diabetes. To achieve this, data were collected through questionnaire and interview surveys, shoe upper materials analysis and foot measurements. In addition, Product Design Specification (PDS) and design framework were formulated. And functional footwear prototypes were designed, constructed and assessed. The data from the questionnaire survey indicate that up to 75% of the diabetic subjects have not received information about the type of footwear they should wear most often. The study revealed that the patients have very poor knowledge about diabetes and its complications, foot care, and the use of appropriate footwear. It was discovered that up to 53% female and 37% male of the patients were wearing slippers most often. Similarly, the findings from the medical doctors interviewed show that up to 66% of the patients were wearing slippers or slip-on (with no fastening mechanism) most often. The research revealed that financial constraint was a key factor to use of appropriate footwear by the patients. Many use cheap footwear regardless whether they provide the required protection and comfort to their feet or not. It was found out that specialist knowledge among medical doctors regarding foot care and provision of special footwear like orthopaedic and diabetic footwear to patients was very low. The shoe upper materials analyses demonstrated that leather has good physical properties required for making diabetic footwear. Data from the measurement of feet indicated that no individual’s feet are exactly the same even as people wearing the same shoe size might not have the same foot dimensions. It was concluded that these differences could have considerable effects on the shoe wearer. From the measured values, the tolerable allowance was found to be 3.4mm and 3.5mm for male and female subjects respectively. The fitting and comfort assessment of the prototypes have shown that some parts of the last used to make the prototypes would require amendments in order to accommodate minor foot deformities properly. The findings from the research were used to develop PDS and a research framework which could be used as a guide for diabetic footwear design and construction. Finally, the contributions of this research to knowledge and critical areas that would require further investigations were outlined.

Full textAbstract:
During a forensic investigation, the recording of evidence in high detail with no distortion and limiting the loss of information is paramount. This could mean the difference between finding a possible offender or the removal of an innocent party from an investigation. Although the current method of recording three dimensional footprints records fine and minimises distortion, it still suffers from a loss of information due to the conversion of a three-dimensional subject into a two-dimensional image. Recent studies into the uses of photogrammetry has highlighted its usefulness in recording an object with high detail and little to no distortion while maximizing the amount of information retained in the three-dimensional model.

Self-regulatory Code of Conduct has widely been adopted by international brands to manage CSR issues in apparel and footwear supply chain for the last 2 decades. Increasingly, more apparel and footwear brands started to expand CSR scope to include environmental management in their supply chain. However, only very few international brands have disclosed their efforts on environmental management in their supply chain. This study aims to find out how apparel and footwear brands implement environmental management in their supply chain. Furthermore, what motivates them to carry out environmental management, and lastly, what challenges the industry encounters in carrying out effective environmental management. Primary and secondary data research were carried out in this study. Primary research, in a form of self-administered survey, was conducted for 11 brands and 15 of their respective suppliers. Secondary research was conducted through desktop research to gather additional information from brands, NGOs, academic studies and news.
The study revealed environmental management in apparel and footwear supply chain is becoming more important. However, most of the brands’ approaches on environmental management are loose (i.e. lack industry-wide sustainably environmental management strategy), and small in scope (i.e. first tier supplier only). It is suggested apparel and footwear brands should improve effectiveness of environmental management program in their supply chain, by applying different implementation strategies internally, with both brands’ and suppliers’ governments, suppliers as well as their stakeholders.published_or_final_version

When it comes to mature manufacturing activities, such as the production of shoes, where only a few technical and organizational characteristics are not shared by all actors, this question becomes even more critical. In order to explore this problem, this work relies on a simple case study, placing footwear industry in focus and following the examples of China, Italy and Brazil - countries that show very different strategic behaviors in that sector. Taking advantage of the conclusions advocated by path dependence theory, on the importance of considering longitudinal analysis when evaluating characteristics and performance of an industry, this research seeks to identify crucial points, in the course of historical events, that could have affected the overall position currently held by those countries. Conclusions show the existence of several key events, which are characterized by randomness, increasing returns and technological interdependence. In addition, social, cultural and public policies considerations seem relevant as well, contributing to lock companies inside strategies from which it is hard to detach.

Retailers collect information regarding consumer purchases on a transactional basis. This data is not completely being leveraged by manufacturers in the footwear and apparel industry to increase on-shelf availability. However, certain apparel and consumer products companies have developed best-in-class methods for collecting and utilizing data to enhance supply chain visibility and to drive increased sales. A description of these best-in-class practices is provided, strategies to use the data are presented, and the importance of collaboration among supply chain partners is discussed. Further, point of sale data from a footwear and apparel manufacturer is analyzed to illustrate how the data can be leveraged to predict subsequent season sales, to improve forecasting accuracy, and to allocate replenishment inventory more effectively.

Full textAbstract:
This research is a part of CoReNet (Customer-ORiented and Eco-friendly NETworks for healthy fashionable goods), an European 7th Framework Program project, whose objective is to implement innovative methods and tools to fulfil needs and expectations of specific target groups – elderly, obese, disabled and diabetic people – by improving the supply network structure of the European Textile, Clothing and Footwear Industry (TCFI) to produce small series of functional and fashionable clothes and footwear.
This thesis particularly focuses on the footwear sector and analyses how the European fashion footwear companies could reengineer their supply networks to address the needs of the project target groups.
In order to stay competitive, European footwear companies need to enter new markets implementing innovative production methodologies based on networking economy. In fact, footwear sector has become a global industry where competition is planetary and key players are no longer concentrated only in Europe and North America but even in emerging low labour cost countries, because of the combined effects of labour intensity, low entry and exit barriers, and changes in international trade regulations. Moreover, the overall performance of this industry is deeply affected by unpredictable and seasonal demand as well as emerging consumers’ needs in terms of comfort, health and environmental attention. This context forces companies to rethink their strategies. The production of small series of specialized and customized high value added products for the project target groups represents a key opportunity for European Footwear Small Medium Enterprises (SMEs) to foster their competitiveness entering new niche markets.
Comparing literature and multiple case studies from the fashion and orthopaedic footwear supply networks , this research aims at highlighting the guidelines for designing an innovative reference model for footwear supply networks. Along this vein the present proposal addresses the design, production and distribution of small series of healthy and fashionable goods for specific target groups, particularly through personalised and comfortable shoes.
The reference model aims at supporting collaboration along the whole value chain in the footwear sector to get and manage consumer data to know their needs, involve consumer into design and product configuration phases, exchange consumer data through adequate data models and secure systems, manage the collaboration with suppliers and other partners in order to plan and distribute on time, implement innovative manufacturing tools delivering the product to the final customer, monitoring the quality and sustainability of productsPer essere competitive, oggigiorno le piccole e medie aziende europee necessitano di entrare in nuovi mercati, tramite l’implementazione di innovative metodologie di produzione basate sulla networking economy. La tematica di ricerca della tesi si inserisce nel contesto del progetto europeo del 7° programma quadro CoReNet (Customer-ORiented and Eco-friendly NETworks for healthy fashionable goods, FP7-2010-NMP-ICT-FoF, n. 260169), orientato alla definizione di nuove metodologie e strumenti per la gestione di supply network del settore tessile, abbigliamento e calzaturiero europeo (TCFI). Con lo scopo di proporre nuovi modelli manageriali collaborativi per la produzione manifatturiera con particolare attenzione verso la sostenibilità ambientale, il progetto mira a supportare la produzione e fornitura di piccole serie di prodotti per soddisfare le esigenze ed aspettative di emergenti segmenti di mercato quali persone anziane, obese, disabili e diabetiche (in seguito Target Group) con prodotti che rispondano ai loro requisiti funzionali e al contempo presentino un design accattivante. La presente tesi si concentrerà sul settore calzaturiero europeo al fine di fornire un modello di business per aziende del mondo fashion che vogliano implementare la produzione di piccole serie di calzature che soddisfino in pieno i requisiti dei target groups sopra elencati, con particolare attenzione ad una dimensione del Best Fit che garantisca al cliente di avere un prodotto configurato per le proprie esigenze. Attraverso un’analisi della letteratura comparata, ad una “as-is” analysis dei supply network dei settori calzaturiero fashion e ortopedico (settore che attualmente fornisce i segmenti di mercato di interesse) e tramite una metodologia di multiple case-studies, la presente ricerca si propone di sviluppare un innovativo reference model per migliorare la gestione del supply network del settore calzaturiero. Il modello evidenzierà le best practices necessarie alle piccole e medie aziende del fashion footwear per aggredire nuove nicchie di mercato, integrando inoltre le best practices del settore ortopedico. Applicando la metodologia BPA (Business Process Analysis) e BPR (Business Process Re-engineering) , la ricerca propone inoltre una mappatura delle più importanti caratteristiche, procedure e tecniche per gestire la produzione, la customizzazione e i processi di rete nel supply network

Full textAbstract:
Orthopaedic footwear design has traditionally been a craft process. In service delivery, this poses problems of delays in production and inconsistency in quality of fit, function and cosmetic appearance. Advanced technology, in the form of techniques for measurement and computer-aided design ( CAD) systems, is proposed to solve some of these problems. The thesis examines the clinical needs and analyses the application philosophy of such technology to related medical applications. The limitations of current understanding of technical requirements for plantar stress measurement are probed through experimental work to evaluate the effects of spatial resolution and threshold, and three case studies of interest in shoe insert prescription and design are presented. The design of shoe inserts requires consideration of both interface pressure and shape: a further study evaluates the basic information that is required to simulate aspects of the manual shaping process by a computer algorithm. The design of the shoe upper is another stage of vital importance to both fit and appearance. In the volume trade, CAD systems have been extensively developed: the potential to develop on from this established technology is explored via a trial involving the provision of computer-designed shoes for ten patients. From the above investigations into aspects of footwear design, the stages of the integrated system are identified and considered with regards to their service and technology requirements. A description is given of the launch of an anglo-dutch project to develop such a system.

A power generating system was designed to passively harness some of the kinetic energy available during walking. The system included a rotary arm extending down from the sole, which ultimately drove a pair of small electrical generators through a stepped-up gearbox. A one-way clutch mechanism was used to transmit torque to the gearbox. This allowed for additional spin following the initial impact of a step, also preventing lockup due to rotary inertia in the gears. The entire generator system was designed to fit in the heel of a standard running shoe, with the rotary arm compressing once during each heel strike. The final system produced a peak power of 1.61 Watts during the heel strike and an average power of 58.1 mW across the entire gait. To maximize power transfer, an ideal load was determined for the two DC generators connected in series. While the average power generated was below the desired 250 mW, initial calculations show this level can eventually be reached or exceeded with the addition of a flywheel to each generator shaft, or a spring to store more energy from the heel-strike.

After a deep economic crisis that started in 2014 and the entrance of Chinese products in the Brazilian footwear market, many manufacturers and retailers have experienced drop in sales and mass layoffs. These events served as a trigger for the study of the underlying factors that have caused the unfortunate events affecting the footwear industry. The purpose of this paper is to gather an industry perspective on what are the main threats the Brazilian footwear industry is facing nowadays and assess whether they are long or short term ones. In order to understand how these factors have impacted in the long term competitive advantage of the chain, 4 interviews were conducted with people working for a retail chain, a questionnaire was sent out to 9 manufacturers of leather shoes, and an online survey was sent out to more than 100 men about their consumption habits of footwear. The changes perceived in consumer preferences represented the biggest threat, given that new trends related to sports shoes and sneakers shifted the focus of the consumer towards international brands and shoes made of different material rather than leather, such as rubber, textile and EVA, mainly produced in China. This threat represents not only a temporary state of the fashion trends, but rather a long term one based on technological innovation and research that are permitted these companies not only with superior products, but also with lower production costs derived from cost efficiencies which are hard to compete with and imitate by the local manufacturers.
Após uma profunda recessão iniciada em 2014 e a entrada de produtos chineses no Mercado de calçados brasileiro, muitos fabricantes e varejistas enfrentaram queda nas vendas e demissões em massa. Esses eventos serviram como gatilho para o estudo dos fatores subjacentes que causaram os eventos lamentáveis que afetaram a indústria calçadista. O propósito deste estudo é consolidar a perspectiva da indústria sobre quais são as maiores ameaças que o mercado de calçados brasileiro enfrenta nos dias de hoje e avaliar se são ameaças de longo ou curto prazo. Para entender como esses fatores impactaram na competitividade da cadeia, 4 entrevistas foram conduzidas com pessoas trabalhando para uma rede varejista, um questionário foi enviado para 9 fabricantes de calçados de couro e uma pesquisa online foi enviada para 100 homens sobre seus hábitos de consumo de calçados. As mudanças percebidas relacionadas às preferencias do consumidor representaram a maior ameaça, dado que novas tendências voltadas para calçados esportivos e sneakers mudaram o foco do consumidor para marcas internacionais e calçados produzidos com outros materiais que não o couro, como borracha, tecido e Eva, majoritariamente produzidos na China. Essa ameaça representa não apenas um estado temporário das tendências da moda, mas sim uma de longo prazo baseada em inovação tecnológica e pesquisa, que permitiu que essas empresas não só fabricassem produtos superiores, mas também com custos de produção muito mais baixos devido a ganhos de eficiência que são difíceis de competir e de serem imitados pelos fabricantes locais.

Full textAbstract:
In footwear testing, the human wear participation method requires a long period and high cost to conduct the experiments and may expose the participants to injury risks. The virtual testing method, which uses computer simulations, faces significant challenges in modelling the complex geometry and realistic testing conditions. Thus, with the ability to stably continuously repeat thousands of testing cycles to reduce the testing time, a third method which uses mechanical devices and automatic systems is preferred in footwear testing. However, available systems do not possess a realistic representation of the human foot, cannot reproduce the wear conditions accurately, and do not mimic properly human running gaits. This thesis addresses the development process of a robotic running foot (RRF) for footwear testing.

Full textAbstract:
There is an emerging consensus amongst economic policy makers that amongst the most important development problems facing South Africa today are the extremely high unemployment levels (estimated at 40% of the formal labour force) and the need to satisfy the basic needs of South Africa's population (ie, food, shelter, clothing and footwear etc). There is also agreement that in order to achieve these twin objectives it is necessary to obtain positive and increasing economic growth rates. The question of how these high and sustainable economic growth rates can be achieved has spawned an intense debate about South Africa's future growth path. This debate about South Africa's economic future after Apartheid is based on differing evaluations of the opportunities offered by the country's current resource endowments and the constraints inhibiting growth (Moll, 1991a, 1991b; Kaplinsky, 1991; Jordan, 1991, Levy, 1991). Some writers1 have argued that a low wage, labour intensive export strategy is the only way that South Africa can rapidly create employment and meet the needs of international competition (Moll, 1991a). Moll therefore argues that increasing the demand for unskilled labour will benefit the poor most. To compete successfully internationally on the basis of low wages (as Moll suggests) is only possible by increasing relative poverty, resulting in increases in absolute poverty, it has been argued (Kaplinsky, 1992). The recent literature (Amsden, 1989; Wade, 1990) on the success of the East Asian NICs (particularly South Korea and Taiwan) strongly refutes the neo-classical view (Little, 1979; Lai, 1983) that developing countries should grow by exploiting their static Comparative Advantage (CA), that is, exploiting the availability of abundant cheap labour. These writers (Amsden, 1989; Wade, 1990) argue that developing countries can move up the value added chain - making it possible for them to pay relatively higher wages - by selective intervention in the market A recent World Bank study (Levy, 1991) analyses the potential of South Africa's manufacturing sector to move on to a dynamic labour-demanding growth path. In analysing the potential of the Garment Sector (the most labour-intensive sector), Levy (1991) argues that South Africa's international comparative advantage lies in the mid- to-upper end of the world garment industry and expanding expons from this sector will increase employment and allow "moderate increases in real wages". In this paper we develop Levy's proposition - that a labour-demanding expon strategy is possible in South Africa for the Garment subsector - for the Footwear subsector. This study will focus on the Footwear subsector for the following reasons. This is a mature industry which is well-established in South Africa. It still remains labour-intensive and well suited like the garment subsector for a labour demanding growth strategy (Levy, 1992). It has a well developed infrastructure in South Africa. However the relative performance of this sector in comparison to that of countries at similar levels of development (the NICs) has been poor (discussed below). It is striking that Footwear has been a leading export sector for the most dynamic, Developing, as well as, Southern European economies during the 1970s and 1980s (Taiwan, Korea, Brazil, Italy, Spain, Portugal, China). Two sets of questions arise from the above discussion. Firstly, like the manufacturing sector as a whole, the performance of the South Afi can Footwear subsector has been unspectacular during the 1970s and 1980s. Why has ihis been so? What is the capability of the Footwear sector to supply the domestic market and to compete internationally ie, export? What are the implications of this for industrial policy? What incentives have been supplied to support the development of this sector and how effective have they been? What incentives will be required to advance the restructuring and development of this sector? What institutions exist in support of this industry and how can these institutions be developed and extended? Secondly, as South Africa develops a more outward oriented manufacturing strategy, it will have to understand the changing nature of international markets and international competition. How have these markets changed? What is the new basis of international competitiveness? What are the implications for South Africa? The objective of this study is to attempt to answer these two sets of questions. The second set of questions will not be answered in any detail in this study, but will draw extensively on a study undertaken by the author (see Ismail, 1992). Previous attempts at developing an analyses and strategy for the industry have been inward oriented (see Van Wyk's IDC Report, 1988) and ad hoc (BTI, 1990). Whilst Sid Cohn's Strat Plan 2000 has gone furthest in developing a systemic approach to the footwear industry, his focus on subcontracting as the main (labour) cost cutting measure has only served to gloss over the underlying inefficiencies of the industry in the management of raw materials and production. We provide a brief summary and critique of these strategies below before presenting a summary of our argument.

Full textAbstract:
This thesis describes a successful attempt to automate a manual process in footwear industry. The process is called skiving of leather components and it is one of the early processes necessary for the assembly of shoe uppers. Skiving is the localised thinning of leather components, mainly at some of their edge regions. The purpose of skiving is to produce quality decorative edges or more importantly to enable attaching and joining components without forming thick, discomforting and weak joints. Although other processes in footwear manufacturing have been subject to partial or full automation, skiving has been performed for decades now with a standard mechanism that requires 3-dimensional manipulation of the components by a human operator. This research work was directed towards two main aims. One was to establish a novel method on the basis of which skiving may be performed without the need of human assistance. The developed method is called dynamic matrix skiving and it is capable of performing skiving on leather components by generating and actuating skive patterns as sets of finite elements of skived area to a given resolution. Following derivation and study of the method for skiving, the second phase was aimed at implementing a fully automatic skiving system. The main requirement from the system was to be an intelligent, component oriented, flow through, processing device. This required the capability to receive input components at any orientation and position along its transport mechanism, to recognise them as to their identity and relative position, and to perform skiving upon them without moving them or disturb their continuous flow throughout the entire operation. Individual chapters in this thesis describe the study and experimentation with regards to dynamic matrix skiving, and all logical steps taken to identify the necessary elements and implement their integration to produce the automated skiving system. The concluding part of this work includes presentation of the results obtained from the automated system, and it identifies the areas where further research and development is needed in order to improve the quality of its output.

Full textAbstract:
Den forensiska vetenskapen innefattar en mängd olika vetenskaper som tillämpas för att bistå och besvara frågor av intresse för rättsväsendet. Skoavtrycksjämförelser har använts sedan slutet av 1700-talet för att bistå i brottsutredningar. Genom att undersöka egenskaper hos ett skoavtryck kan en forensiker ge utredaren värdefull information om skon och ibland även om bäraren. I bästa fall är skoavtrycket så unikt att det kan individualiseras och identifieras till en specifik sko.
För att underlätta och förbättra den forensiska bevisvärderingen är det av stort intresse att statistiskt erhålla förekomsten av ett bevis. Genom att samla in data gällande sulmönster och sedan etablera en databas kan styrkan hos ett specifikt skoavtryck fastställas. I denna studie samlades 687 avtryck in slumpmässigt och lades in i ett visualiserat databasklassificeringssystem, SIMSALAPIM, varpå en statistisk utvärdering utfördes.
Resultatet i denna studie visar på att ett specifikt sulmönster generellt förekommer endast en gång i databasen, varför det kan sägas att ett skoavtryck tillför en viss styrka/värde som forensiskt bevis även om det inte besitter några individualiserande detaljer. Vidare, genom ytterliggare statistiska utvärderingar, kunde även ett samband mellan ålder och typ av sko ses.
The Forensic Science comprises a variety of sciences that are applied in order to assist and answer questions of interest to the legal system. Since the end of the 18th century footwear impression comparison has been applied to assist in crime investigations. By examining the characteristics of a footwear impression the forensic scientist may provide the investigator with valuable information about the footwear and sometimes even about the wearer. Ultimately, the footwear impression is so unique that it can be individualized and identified to a specific shoe.
In order to facilitate and improve the forensic evidence evaluation it is of great interest to statistically establish the prevalence of evidence. By collecting data of outsole patterns and then recording it in a database the strength of a specific footwear impression can be determined. In this survey 687 impressions were randomly collected and recorded in a visualised database classification system, SIMSALAPIM1, whereupon a statistical evaluation was performed.
The result of this survey indicates that a specific outsole pattern typically only occurs once in the database, wherefore it can be stated that any footwear impression provides some strength/value as forensic evidence even though there are no individual characteristics present. Moreover, through additional statistical evaluations, a relation between age and shoe type also was revealed.

Background: The aim of this paper was to create an updated Australian guideline on footwear for people with diabetes. Methods: We reviewed new footwear publications, (international guidelines, and consensus expert opinion alongside the 2013 Australian footwear guideline to formulate updated recommendations. Result: We recommend health professionals managing people with diabetes should: (1) Advise people with diabetes to wear footwear that fits, protects and accommodates the shape of their feet. (2) Advise people with diabetes to always wear socks within their footwear, in order to reduce shear and friction. (3) Educate people with diabetes, their relatives and caregivers on the importance of wearing appropriate footwear to prevent foot ulceration. (4) Instruct people with diabetes at intermediate-or high-risk of foot ulceration to obtain footwear from an appropriately trained professional to ensure it fits, protects and accommodates the shape of their feet. (5) Motivate people with diabetes at intermediate-or high-risk of foot ulceration to wear their footwear at all times, both indoors and outdoors. (6) Motivate people with diabetes at intermediate-or high-risk of foot ulceration (or their relatives and caregivers) to check their footwear, each time before wearing, to ensure that there are no foreign objects in, or penetrating, the footwear; and check their feet, each time their footwear is removed, to ensure there are no signs of abnormal pressure, trauma or ulceration. (7) For people with a foot deformity or pre-ulcerative lesion, consider prescribing medical grade footwear, which may include custom-made in-shoe orthoses or insoles. (8) For people with a healed plantar foot ulcer, prescribe medical grade footwear with custom-made in-shoe orthoses or insoles with a demonstrated plantar pressure relieving effect at high-risk areas. (9) Review prescribed footwear every three months to ensure it still fits adequately, protects, and supports the foot. (10) For people with a plantar diabetic foot ulcer, footwear is not specifically recommended for treatment; prescribe appropriate offloading devices to heal these ulcers. Conclusions: This guideline contains 10 key recommendations to guide health professionals in selecting the most appropriate footwear to meet the specific foot risk needs of an individual with diabetes.

Full textAbstract:
Although footwear has been recognised as a risk factor for falls in older people, it remains unclear as to which features of shoes are beneficial or detrimental to balance. This project aimed to systematically investigate the effects of common shoe features, namely: an elevated heel, a soft sole, a hard sole, a flared sole, a bevelled heel, a high-collar and a tread sole, on balance and gait in older community-dwelling people. The experimental shoes were compared to standard shoes in three studies examining: (i) standing balance, leaning balance and stepping in 29 older people, (ii) centre of mass (COM)-base of support (BOS) margins, vertical and braking loading rates, and perceived shoe comfort and stability in 11 young and 15 older people walking on even and uneven surfaces, and (iii) temporal-spatial gait variables, pelvis acceleration, and gait termination in 10 young and 26 older people, on level, irregular and wet surfaces. Elevated heel shoes impaired overall performance in functional tests of balance and stepping. They were also perceived as lacking comfort and stability and led to a conservative walking pattern characterised by increased step width and double-support time, reduced braking and vertical loading rates and medio-lateral (ML) pelvis accelerations on various surfaces. Soft sole shoes increased lateral COM-BOS margin and step width, indicating reduced ML walking stability. When wearing these shoes, subjects had longer total stopping times and on the wet surface, smaller step lengths and shoe/floor angles at heel strike, suggesting a potential risk of slipping. When wearing high-collar shoes, subjects had better balance as demonstrated by small but significant increases in lateral COM-BOS margin, double-support time and step width, and decreases in ML pelvis accelerations on varying surfaces and in total stopping time on the wet surface. Shoes with hard, flared or tread soles or a bevelled heel did not affect balance. In conclusion, providing that they are fitted, have adequate fastening and perhaps a slip-resistant sole, shoes with a low square heel, a sole of medium hardness (shore A-40) and a high-collar provide the greatest stability for older people when walking on dry, wet and irregular surfaces.

Full textAbstract:
Therapeutic footwear is provided to patients with the primary aims of reducing foot pain and improving foot health. Therefore, it is of concern that patients choose not to wear it. This choice has been attributed to its poor appearance. However, there may be other reasons for this choice and the reasons may be more complex than previously acknowledged. Therefore, the aim of this study was to investigate the users’ experiences of this footwear. In the context of this study the ‘users’ are women with rheumatoid arthritis. This study was based on an interpretive phenomenological approach (IPA) that employed conversational style interviews to gather data. Ten women with RA and experience of wearing the footwear were recruited and following ethical approval the interviews were carried out, transcribed, organised and analysed. Five organising themes emerged as findings. These were the participants: • feelings about themselves, • feelings about the footwear, • unmet needs and expectations, • behaviour with the footwear and • feelings about the consultation with the practitioner. The final, global theme was that the patient/practitioner consultation has a powerful influence on the women’s feelings about themselves, the footwear, their expectations of it and their behaviour with it. This study has provided insight into their experiences of this footwear in that, unlike any other intervention, it replaces something that is normally worn and is part of an individual’s perception of self and their perception of how others see them. The footwear impacts more on women’s emotions than previously acknowledged and in addition, it has been found that the consultation influences their emotions and behaviour with the footwear. As well as improvements in footwear design and the service that delivers it, the training of the practitioners in a more patient focussed consultation style could improve the women’s experience and engagement in the footwear as a health intervention, as well as something that is ‘worn’.

Full textAbstract:
Rocker profiles are one of the most commonly prescribed footwear modifications provided to individuals with impaired rollover. Impaired rollover is caused due to loss of neuromuscular function (i.e. stoke) or orthotic ankle constraint. When rollover is impaired, continued forward progression is interrupted and walking gait becomes less efficient (i.e. increased energy expenditure). Rocker profile footwear modifications are designed to mimic the functions of the anatomical ankle-foot rockers and provide its users with a smooth and efficient rollover. However, while there is theory governing the design of a rocker profile and subjective descriptions of rocker profile function, the extent to which a rocker profile footwear provides rollover has not yet been quantified. The aim of this study was to quantify effective and ineffective rollover and test whether our rocker profile provides effective rollover. We hypothesized that healthy subjects (n=4) walking with orthotic ankle constraint and the rocker profile (STOP) would have no change in rollover and energy expenditure outputs compared to walking with orthotic ankle free and rocker profile (FREE); but that healthy subjects (n=4) walking in STOP would have a change in rollover and energy expenditure outputs compared to walking with orthotic ankle constraint and no rocker profile (STOP-NR). To test this hypothesis, rollover was quantified as stance phase duration, cadence and radius of curvature and energy expenditure was quantified as heart rate and rating of perceived exertion. In addition to these outputs, we analyzed the ground reaction forces and duration of stance in early, middle and late stance period to determine the effects of the rocker profile footwear components. Through the rollover and energy expenditure outputs of the STOP, FREE and STOP-NR conditions, we quantified effective rollover as 0.29 (0.01) radius of curvature with a heart rate of 110.5(6.7) bpm and ineffective rollover as 0.69(0.12) radius of curvature with a heart rate of 131.5 (8.1) bpm. By creating this scale, we were able to determine that our rocker profile provided effective rollover (0.34[0.04] radius of curvature with a heart rate of 111.3[8.3] bpm). However, a future study with a greater sample size is needed to confirm these results.

Full textAbstract:
The personalisation of footwear offers advantages not only for runners, but to anyone who wishes to become more active. Additive manufacturing (AM) technology has the potential for making footwear personalisation economically feasible by allowing direct manufacture from CAD models and its tool-less capability. This thesis aims to develop and explore the process of footwear personalisation using AM and evaluates such footwear in terms of discomfort and biomechanics. To start to explore this process a repeated measures pilot study was conducted. Six recreational runners had anthropometric measurements of the foot taken and the plantar surface of both feet scanned. From the scans and measurements, personalised glove fit insoles were designed and manufactured using AM. Participants were then fitted with footwear under two experimental conditions (control and personalised), which were compared in terms of discomfort, performance and biomechanics. The findings of this pilot confirmed the feasibility of the personalisation process. A longitudinal study was then conducted to evaluate the short and medium term use of personalised footwear in terms of discomfort and biomechanics. A matched pairs study design was utilised and 38 recreational runners (19 pairs) were recruited. Control (generic shape) and personalised geometry insoles were designed and manufactured using AM. The participants wore the footwear each time they went running for a 3-month period. They also completed an Activity Diary after each training session and attended 4 laboratory sessions during this period. The results showed significantly lower discomfort ratings in the heel area and for overall fit with the personalised insoles. However, discomfort was reported under the arch region for both conditions (supported by the Activity Diary), indicating that the foot scanning position and material may need modifying. With regard to the biomechanics, the personalised insoles also led to significantly lower maximum ankle eversion and lower peak mean pressure under the heel, which are potentially positive effects in terms of reducing injury risk. A case study is then reported which explored foot capture using a dynamic scanner for the design and manufacture of insoles using AM. Through the development of four insoles, it was found that the selection and manipulation of the scan data from the series of frames generated during ground contact were the most demanding elements of the process. Finally, recommendations and guidance are given for the footwear personalisation process (foot scan position, anthropometry, insole design and AM), together with its potential benefits and limitations.

Full textAbstract:
Very few standards exist for tting products to people. Footwear fit is a noteworthy example for consumer consideration when purchasing shoes. As a result, footwear manufacturing industry for achieving commercial success encountered the problem of developing right footwear which is fulfills consumer's requirement better than it's competeries.
Mass customization starts with understanding individual customer's requirement and it finishes with fulllment process of satisfying the target customer with near mass production efficiency. Unlike any other consumer product, personalized footwear or the matching of footwear to feet is not easy if delivery of discomfort is predominantly caused by pressure induced by a shoe that has a design unsuitable for that particular shape of foot.
Footwear fitter have been using manual measurement for a long time, but the combination of 3D scanning systems with mathematical technique makes possible the development of systems, which can help in the selection of good footwear for a given customer.
This thesis, provides new approach for addressing the computerize footwear fit customization in industry problem.
The design of new shoes starts with the design of the new shoe last. A shoe last is a wooden or metal model of human foot on which shoes are shaped. Despite the steady increase in accuracy, most available scanning techniques cause some deficiencies in the point cloud and a set of holes in the triangle meshes.
Moreover, data resulting from 3D scanning are given in an arbitrary position and orientation in a 3D space. To apply sophisticated modeling operations on these data sets, substantial post-processing is usually required.
We described a robust algorithm for filling holes in triangle mesh. First, the advance front mesh technique is used to generate a new triangular mesh to cover the hole. Next, the triangles in initial patch mesh is modified by estimating desirable normals instead of relocating them directly. Finally, the Poisson equation is applied to optimize the new mesh. After obtaining complete 3D model, the result data must be generated and aligned before taking this models for shape analysis such as measuring similarity between foot and shoe last data base for evaluating footwear it.
Principle Component Analysis (PCA), aligns a model by considering its center of mass as the coordinate system origin, and its principle axes as the coordinate axes.
The purpose of the PCA applied to a 3D model is to make the resulting shape independent to translation and rotation asmuch as possible. In analysis, we applied "weighted" PCA instead of applying the PCA in a classical way (sets of 3D point-clouds) for alignment of 3D models.
This approach is based on establishing weights associated to center of gravity of triangles. When all of the models are aligned, an efficient algorithm to cut the model to several sections toward the heel and toe for extracting counters is used. Then the area of each contour is calculated and compared with equal sections in shoe last data base for finding best footwear fit within the shoe last data base.

Introduction
Ill-fitting footwear is one of the well-known risk factors causing foot ulceration in the diabetic population. Current literature for fitness of foot dimensions is insufficient, especially on foot-shoe length and foot-shoe width measurement in absolute numerical differences. The aims of the study were to compare and identify the footwear fitness in diabetic patients with peripheral sensory neuropathy, diabetic patients without peripheral neuropathy and non diabetes.
Materials and Method
Diabetes patients were assessed for peripheral sensory neuropathy by two sensory tests, 10-g monofilament test using 10-g Semmes-Weinstein monofilament and vibration perception threshold test using neurotheisometer. Abnormal results of both tests indicated diabetes sensory neuropathy. The dimensions of foot length and foot width were determined by the Brannock device while internal shoe length and internal shoe width were measured by an inside caliper. The mean of internal shoe-length difference and shoe-width difference of three groups were calculated and compared. Reference ranges of 10-15mm of shoe-length difference and 0-7mm were selected from past literature. The values of shoe-length and shoe-width differences were dichotomized into correct and incorrect fit category. Footwear fitness of the three groups was compared. Demographics of patients, information on self foot care, shoe size check and footwear habit were collected for correlation analysis.
Results
Data was collected from 20 diabetes patients with sensory neuropathy, 60 diabetes patients without neuropathy and 40 non diabetes controls. There were significant difference in shoe-length difference among three groups, with larger shoe-length difference in diabetic neuropathy group (left: 21.9mm, / right: 21.7mm), followed by non neuropathy diabetes (left: 15.2mm, / right: 15.5mm) and controls (left: 13.4mm, / right: 14.5mm) (left p=0.002 / right p=0.008). The shoe-length differences of both diabetes groups exceeded the reference range, indicating long footwear. No significant difference was reported related to shoe-width difference. Analysis of shoe fit category showed around 15-17% of diabetes patients were wearing correctly fit shoes in both length and width. A high prevalence of diabetes patient had ill-fitting footwear while nearly half of them wear shoes with correct width but incorrect length. There is nearly no correlations between shoe-length fit, shoe-width fit and frequency of self foot check, frequency of footwear size check and frequency of diabetic footwear education.
Discussion
Most diabetes patients wear ill-fitting footwear, especially those with peripheral sensory neuropathy when compared to control group. There is significant difference in shoe-length difference among the three groups, with reference to the 10-15mm range as the gap length allowance. Diabetic patients tend to wear long and loose footwear in this study even they had past foot education and practice proper self foot check regularly. These might imply incomprehensive proper diabetic footwear education and self footwear assessment in current diabetes care pathway. These components are essential in diabetes foot care and people with diabetes are highly recommended to select a pair of good fit footwear. Further research is required to standardize the methodologies of measurement in foot dimensions and footwear fitness as well as investigate on relations of additional foot parameters in shoe fitting.published_or_final_version

The field of impression evidence analysis employs the concept of uniqueness, in order to arrive at a conclusion of association, between an evidence and a reference sample. However, the idea of uniqueness and its application in this field of forensic science, is considered conceptual by a few practitioners and courts, as it fails to be supported by sound scientific studies and experimentation. This study aims to provide a scientific basis for the idea of uniqueness and its validity in footwear impression evidence analysis. Additionally, this study also aims to determine the presence or the lack of, a variation, between outsole impression size and the outsole size of the footwear that created the impression.
The study required 3 volunteers to each, create 30 touch impressions and 10 step impressions with the same footwear, utilizing the EZID^TM Footwear Impression System manufactured by Sirchie®.
Using Adobe Photoshop^TM CS4, the 30 touch impressions were analyzed by sequentially overlaying the impressions onto each other, in an effort to determine the area of overlay agreement between the impressions being analyzed.
Subsequently, the 10 step impressions were examined by measuring the size of the impression created on the EZID Impression test cards, from the toe area to the heel area of the outsole impression. The data obtained indicate that, even under controlled settings and while attempting to maintain constant pressure through the creation of footwear impressions, it is impossible to generate prints that overlay perfectly. Further, the data also shows that a negligible variation occurs between the footwear outsole length and the length of the impression it creates, using the EZID^TM Footwear Impression System. This variation, however, is too small to cause any major hindrances in the estimation of footwear size.

Domestic footwear industry is now under the globally competitive environment. The changes of environment bring a certain degree of impact and influence toward the enterprise’s prospect. In recent years, our government put more emphasis on high-tech industry. Highly-educated professionals are prone to enter science park for employment. Also, poaching is rampant among different industries, many manufacturing engineers of footwear industry resort to job-hopping for higher pay, which result in enterprise''s great loss. If we can understand the key factors that affect manufacturing engineers’ job satisfaction, this study would be an important reference for managers, and thus enhance manufacturing engineers’ loyalty and sense of belonging toward company. That is, satisfied employees help to advance performance and productivity, reduce turnover rate, and enhance creativity and loyalty. In this study, one of NIKE’s OEM is choosen to be the research sample. 234 questionnaires were sent out to manufacturing engineers with 213 questionnaires or 91.01% returned. We applied SPSS12.0 to run Reliability Analysis, Descriptive Statistics, One-way ANOVA to do data processing and data analysis, and use One-way ANOVA to examine whether there is significant effect between manufacturing engineers’ Personal Attributes and job satisfaction Correlation Dimension. And we use Pearson Correlation Coefficient to analyze the relationship among job, working environment, manager’s capability, interpersonal relationship, and compensation and benefits. 1. Managers should develop different training programs depending on engineers’ seniority and job grade to place importance on employee training and enhance working ability. 2. After performance evaluation, managers should track for employee’ improvement plans to advance human quality, thus resolve work problems. 3. Redesigning managers’ assessment and performance incentive system, and combining them with employee’s job grade will urge managers to place importance on personnel training, and further enhance enterprise’s competitiveness. 4. Managers should build technology sharing platform to save individual’s effort searching for information and seek quick and effective solution. 5. There should be a cross-sect oral technical team to help engineers improve and resolve problems, to lower their anxiety and enhance team effectiveness.

The study focuses on the development of footwear manufacturing industry. Through interviewing different enterprises and conducting comparative analysis with enterprise A, the study dedicates to find a forward-looking development strategy for footwear manufacturing industry. Since the footwear manufacturing industry are highly related with middle and down-stream manufactures, the importance of vertical integration can’t be emphasized more. The purpose of the vertical integration is to satisfy the needs of clients and to expand the market share through techniques like increasing the output value and enhancing the process rationalization. Then, the comapny integration is purposed for the integration of information automation. With the integration of electronic components and IT systems monitoring process, managers are able to make revision on-site without canceling the whole models. Furthermore, the study explores both the changes in business management and production mode. On one hand, corporate management uses OKR/KPI to maximize management efficiency. On the other, the footwear production changes from the traditional labored-intensive mode into a machine intelligent / automated mode of production. The key for the future will lie in the further integration of brands and factories. The more integrated the regional markets are, the more the enterprise may sustain in the business. In able to be sustainable, the value held previously shall be extended to: Cost expands to Value, Quality expands to Innovation, and Tine of delivery expands to Speed.

The Biomechanical Analysis of Military Footwear ABSTRACT According to the statistics of orthopaedics department of a military hospital in northern Taiwan, there are about 4200 soldiers suffered foot injures every year. Therefore, we tested various military footwear to determine the suitability of current military footwear. The subjects of this research are sports footwear ( athletic shoes, dazzle-paint boots ) and defense boots which are particularly used for the Army. Besides, we had control group which are four pairs of general athletic shoes and three pairs of combat boots. The content of this research can be divided into four parts: 1.questionnaire of satisfaction and need. 2. material test. 3. subject test. 4. the analysis fo the motion of combat skills. After getting of all the data, statistical analysis of various functions for military footwear was then performed. Satisfication of questionary has displayed all military footwear do not over 50%, that means have to take quite a little improvements. The results showed that defense boot’s cushioning ability need improvement. Friction test has displayed that white athletic shoes and dazzle-paint boots can improve outsole pattern using present material. Plantar pressure test has displayed all military footwear had higher pear. Pressure, which should be designed to redistribute pressure to improve comfort and prevent injure. According to the result of the statistic of combat skills, to design new style of military footwear should take walking and running into consideration. Key words: military footwear, cushioning, energy return, plantar pressure, friction
