This has been attributed to shoes with a combination of a thick midsole and carbon fibre plate (carbon plate shoes) first introduced by Nike in their Breaking2 event. There are many theories on how these shoes decrease metabolic cost, including the stiff carbon plate storing and releasing energy, the midsole thickness, and the shoe acting as a teeter-totter system (Patoz et al., 2022). However, no unifying theory has emerged, and the response varies widely across runners. One challenge that has limited the ability to determine how these shoes lower cost is associated with the difficulty measuring the mechanics of the foot and foot-shoe system in vivo. In this pilot study, we address this gap by simultaneously measuring foot bone motion with biplanar videoradiography (BVR) and foot-shoe power in these so called ‘super shoes’.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S117 - S119"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46028123","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}

Compared to human testing, virtual testing with musculoskeletal simulation can provide biomechanical insights with fewer study participants and prototypes (Dorschky et al., 2019). So far, these studies have been performed only retrospectively, meaning that the desired answer was known at the time of virtual study.

This sex-based disparity is associated with differences in neuromuscular control, joint laxity, and anatomical alignment, altering kinetic and kinematic performance profiles (Decker et al., 2003). These differences widen with fatigue, furthering the risk of injury in females (Kernozek et al., 2007). Despite mechanical differences between sex, soccer footwear is designed for male users. With known sex differences in movement patterns and joint loading, it should not be assumed that females are able to withstand the same amount of traction as males. High traction footwear may exacerbate female susceptibility to torsional injury mechanisms, such as those of ACL injury, if rotational resistance exceeds ligament loading capacity (Butler et al., 2012). Cleat outsole properties, such as stud shape, are moderators of rotational resistance at the shoe-surface interface (Butler et al., 2012). However, the effect of stud shape on female mechanics remains unknown.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S199 - S200"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45437220","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}

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}

Similar to the now common modern marathon racing shoes (e.g. Nike Vaporfly), superspikes feature a lightweight, compliant, and resilient midsole foam, often combined with a stiff midsole plate. These shared characteristics in tandem with the abrupt rise of notable middle-distance and distance running performances on the track since their introduction have led to speculations as to if/how much the use of these spikes improve/contribute to a user’s performance (Healey et al., 2022).
