Stack height is an important feature of running shoes, defined as the thickness of material separating the foot from the ground (Esculier et al., 2015). However, the effect of stack heights on running biomechanics has only recently been investigated systematically (Barrons et al., 2023). 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. In this work, we studied the effect of stack height in dependently in a virtual study and a human experiment, to investigate if we can accurately predict the effect of stack height in a virtual study.

Recent footwear designs have resulted in reductions in metabolic cost and decreases in personal best times in runners (Hoogkamer et al., 2018). 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’.

Anterior cruciate ligament (ACL) tears occur at a 3x higher rate in female soccer athletes than males (Wald en et al., 2010). 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.
前交叉韧带(ACL)撕裂在女性足球运动员中的发生率是男性的3倍(Wald等人，2010)。这种基于性别的差异与神经肌肉控制、关节松弛和解剖对齐的差异有关，从而改变了动力学和运动学表现(Decker et al.， 2003)。这些差异随着疲劳而扩大，增加了女性受伤的风险(Kernozek et al.， 2007)。尽管性别之间存在机械差异，但足球鞋是为男性用户设计的。由于已知性别在运动模式和关节负荷上的差异，我们不应该假设女性能够承受与男性相同的牵引力。如果旋转阻力超过韧带负荷能力，高牵引力鞋可能会加剧女性对扭转损伤机制的易感性，例如前交叉韧带损伤(Butler等，2012)。清晰的外底特性，如螺柱形状，是鞋面界面旋转阻力的调节剂(Butler等，2012)。然而，螺柱形状对女性力学的影响尚不清楚。

The selection of spiked shoes can greatly affect sprint performance. In order to enhance propulsion during running, AFT (Advanced Footwear Technology) has been developed in recent years. Some sports manufacturers have been also developing spiked shoes with soft and bouncy(resilient) thick midsole materials, following the change of marathon shoes from thin-soled to thick-soled with a reinforced plate. It has been reported that the use of certain thick sole shoes results in improved running economy in long distance due, in part, to differences in running mechanics (Hunter et al., 2019). On the other hand, the influence of spiked shoes with soft and bouncy midsole materials on sprint performance has not been clarified.

Since their launch in 2016, studies, reports and rumours have surrounded a potential performance boost for Nike’s super shoes (Quealy & Kath, 2019). The combination of novel, lightweight cushioning materials and carbon elements has been taken up by other manufacturers and has also been incorporated into spiked shoes. The impact of super shoes, particularly spikes, on track performance is not well understood (Healey et al., 2022).

Recently, running shoes with a carbon plate embedded in the midsole have been developed to improve running performance. In 2019, Eliud Kipchoge teamed with Nike broke two-hour marathon barrier for his second attempt with a 1:59:40 finishing time. During this event, he had worn carbon plate running shoes, and people around the world became interested in carbon plate running shoes. In a study examining metabolic variables in elite running athletes (Hoogkamer et al., 2018), it was reported that carbon plate running shoes can shorten the record by about six minutes compared to normal running shoes. Therefore, it is necessary to investigate the effect of running shoes with built-in carbon plate on the running biomechanics (Barnes & Kilding, 2019; Hoogkamer et al., 2019).

For older adults, regular physical activity is important for maintaining mobility and independence (Dayley et al. 2000). 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.

In February 2023, 52 professional, club, and collegiate level athletes broke the 4-minute mile barrier all within the span of an hour at Boston University’s indoor track facility. While this track has been known to be fast, another important common feature in this unprecedented feat was the use of what the Track & Field world refers to as ‘superspikes’. 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). One may brush these speculatory comments off as merely anecdotal, but a growing consensus is being observed amongst athletes of all levels. So, the question is whether there is potential validity to these comments.
2023年2月，52名职业、俱乐部和大学水平的运动员在波士顿大学室内田径设施的一个小时内打破了4分钟一英里的障碍。虽然这条赛道速度很快，但在这一前所未有的壮举中，另一个重要的共同特征是使用了田径界所说的“超级钉鞋”。与现在常见的现代马拉松跑鞋(如耐克Vaporfly)类似，超级钉鞋的特点是重量轻、柔韧、有弹性的中底泡沫，通常与坚硬的中底板结合在一起。这些共同的特征与自它们被引入以来中距离和长距离跑步成绩的突然上升相结合，导致人们猜测这些尖峰的使用是否/在多大程度上改善/促进了用户的表现(Healey et al.， 2022)。人们可能会把这些推测性的评论当作轶事而不予理睬，但在各个级别的运动员中，人们正观察到一种日益增长的共识。所以，问题是这些评论是否有潜在的有效性。

Raising in the height of a shoe heel increases the pressure under the forefoot area, which leads to medical problems (Eshraghi et al., 2019). It also interferes with the human natural movement (Cronin, 2014). The conventional high heels can be more comfortable if they are being designed with an advanced technology. The wall thickness and the angle of the connected walls are important factors. The geometry of the structure has a direct effect on the stiffness and the flexibility and comfortability.
