Although walking may be one of effective measures for preventing knee OA because it is associated with the decrease of pain in knee OA (Lo et al., 2022), healthy adults should avoid abnormal body mechanics of knee OA during walking.

Unfortunately, 72% of older adults report their athletic footwear to uncomfortable, potentially discouraging regular activity (Burns et al. 2002). Poor athletic footwear fit in older adults could be a result of shoe lasts typically being designed for young adults (Mickle et al. 2011, Jellema et al. 2019). These shaes may not be appropriate for older adults as the aging foot widens over time due to the flattening of the arch. Further, shoe fit tolerance guidelines may not result in a comfortable fit for older adults as they experience changes in foot sensitivity (Kenshalo 1986). To date, the majority of footwear research has focused on the fit and performance of athletic footwear in young, healthy adults. As such, there is limited research evaluating athletic footwear comfort in aging adults. Specifically, it is unknown which specific changes in foot shape and sensitivity contribute to decreased athletic footwear comfort with age. Determining the foot characteristics associated with comfort in older adults can guide future design innovations in shoes specific to older populations, promoting inclusivity in footwear.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S178 - S179"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46028680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a previous study reported that a softer midsole enhanced running economy (Worobets et al., 2014), Nigg et al. claimed that shoe construction was more effective in improving running performance (Nigg et al., 2020).

A softer or looser boot could dissipate the transfer of power, resulting in less responsive turning. Boot flexion stiffness is affected by boot materials, user anthropometrics, and the skier’s boot closure preferences (Immler et al., 2019). As a result, boot fit is a critical component of performance. Tight-fitting boots result in high foot pressures, which can impair motor control and temperature regulation. In athletic shoes, alternative fit systems result in a more uniform pressure distribution under the foot, including lower peak pressures under the heel and toes (Harrison et al., 2021). Reduced pressure may alleviate symptoms of pain and coldness associated with ski boots (Fontanella et al., 2021), which could improve performance. Ski performance can be parameterized as a set of force attributes during carving turns; specifically, greater force on the downhill foot, force under the forefoot and rate of force development during turn initiation are associated with expert skiers relative to novices.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S97 - S98"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47945772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, endurance running, particularly trail running, drive the runners into an induced-fatigue state which might impair their perception. In addition, fatigue induces changes in running biomechanics which may lead to different running patterns adaptations for both the road (Morio et al. 2020) and trail (Lloria-Varella et al. 2022) runners.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S29 - S30"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42434454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wearing comfort of the footwear upper has also been centred on qualitative evaluation through questionnaires, but recently, the footwear industry, including the IEEE, is making various attempts to quantitatively analyse the wearing comfort of shoe. The pressure generated in the shoe occurs on the plantar and dorsal area of foot depending on the various physical activity. This pressure occurs repeatedly during high-intensity activities and causes damage to skin tissue and deformation of the musculoskeletal system (Mei et al., 2014; Mey et al., 2018). In contrast, the proper pressure distribution generated during exercise makes comfortable feeling for users. The maximum pressure generated from the instep of foot has a significant effect on the user’s perception that the shoe is comfortable (Lindorfer et al., 2020; Mo et al., 2020).","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S59 - S60"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45313494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we divide the human functions to be expanded into four: physical motor function, sensory perception function, cognitive analysis function, and communication function. Human Augmentation research can be divided into two: one is to enhance each human function, the other is to realise remoteness by connecting to cyberspace, or those that use cyberspace to remove various physical restrictions and expand the scale. Human augmentation research includes development of technologies related to wearable sensing technology that comprehends people and situations, human digital twin that instantly converts that data into human evaluation indicators, and intervenes with the results through VR (virtual reality)/AR (augmented reality), audiovisual presentation, and haptic presentation. In the keynote speech, I will introduce Human Augmentation systems with wearable-sensing, digital human modelling, and intervention for concrete applications, such as healthcare services and sports training. Through these Human Augmentation systems, physical and/or mental abilities were improved temporarily. Moreover, continuous intervention with Human Augmentation systems, human physical and/or mental abilities were improved permanently. In order to develop digital human models and intervention systems, it is required to estimate human functions and context from sensing data with artificial intelligence technologies. Here, both deep data that is detailed human functional data corrected in laboratories and big data corrected through actual business services are required. Therefore, the Human Augmentation Research Centre focuses on not only technologies on sensing, modelling, and intervention, but also on services and design. This research framework directs to Servitization, such as changing the business model from selling the Human Augmentation systems to provision of services using the systems. I will introduce a concrete project on servitization with Human Augmentation system in this keynote. Human Augmentation research also focuses on cyberspace. I will introduce case studies of skill training and remote care services using cyberspace (Metaverse). These services are realised remotely by utilising VR/AR technology. In Human Augmentation using cyberspace, it is important not only to value co-creation in the cyberspace (Metaverse) but also to value transfer to the real space (Universe). Namely, services with Human Augmentation systems should change the bodybuild of a user’s avatar in the Metaverse and the real body of the user in the Universe both. For this purpose, we need not only the technology to immerse ourselves in the Metaverse, but also the technology to return the value created in the Metaverse to our bodies and actions in the Un","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S4 - S5"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45747749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anecdotally, some runners report decreased knee pain in maximal shoes. However, research to date has not found any differences at the knee and hip in maximal shoes compared to traditional shoes (Becker & Borgia, 2020; Sinclair et al., 2016). Distal running biomechanics do not appear to change after a 6-week acclimation to maximal shoes (Hannigan & Pollard, 2019), but it’s currently unknown whether proximal biomechanics at the knee and hip may adapt over time, which could explain why some runners find knee pain relief in maximal shoes.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S89 - S90"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44377761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
