Barefoot and minimalist shod running has been encouraged since they could reduce the risks of knee injuries and potentially improve running performance (Perl et al., 2012). One main factor differentiating natural-cushioning shoes from minimalist shoes is the height difference between heel and toe. Natural-cushioning shoes are available in a wide range of drops from 10 to 12mm, whereas minimalist shoes are measured from 0 to 8mm. Shoe manufacturers sell natural-cushioning shoes with 4–8mm heel-to-toe drops to appeal to the market. However, no clear experimental evidence has shown the positive effects of 4–8mm heel-to-toe drop shoes in runners.

Individuals who develop chronic ankle instability (CAI) following a lateral ankle sprain (LAS) often experience diminished proprioception, reduced dynamic stability, and altered movement patterns during landing (e.g. increased plantar flexion and inversion angles) (Simpson et al., 2019). Using external supports (e.g. ankle braces or taping) may reduce the risk of recurrent ankle sprains. However, disadvantages include discomfort, impaired athletic performance, and taping often requires application by a skilled practitioner and loosens over time (Koyama et al., 2014). Soft ankle collars are increasingly popular in sporting footwear, but it is not currently known if these provide positive benefits in individuals with CAI. Complete contact between the collar and the skin over the ankle joint could improve known deficits and ankle motion in CAI (Burcal et al., 2017).

Footwear brands have been trying to provide a well-fitting shoe for a wide variety of foot shapes in order to meet the customer expectations. A typical example is that different shoe lasts have been used in shoe design to accommodate the different dimensions of the foot shapes between male and female. In fact, men’s feet are longer and wider than women’s feet (e.g., Wunderlich and Cavanagh, 2001), which should be related to the anthropometric differences between the sexes. The majority of previous research on the foot shape differences between the sexes has been conducted using 1D or 2D measures, such as arch height, foot circumference and so on. For these variables, relatively small differences between the sexes have been observed when normalized to the foot length (Krauss et al., 2011). However, little is known regarding the 3D shape difference by taking into account the size differences.

With record-breaking performance recently seen in track and field running events and associated with advanced footwear, also sprint spikes are increasingly researched. Current sprint spikes combine multiple features, e.g. lightweight, compliant and resilient foams, tensile bags and high longitudinal bending stiffness (LBS) (Healey et al., 2022). Teasing out performance benefits of sprint spikes, however, remains challenging due to the race task being maximum effort of an individual athlete. It is recommended to research performance of sprint spikes by single-subject analysis given the variation in biomechanical variables among elite sprinters (Bezodis et al., 2014).
随着最近在田径比赛中破纪录的表现，以及与先进的鞋类有关的短跑鞋也越来越多地被研究。目前的冲刺尖峰结合了多种特征，例如轻质、柔韧性和弹性泡沫、拉伸袋和高纵向弯曲刚度(LBS) (Healey等，2022)。然而，由于比赛任务是单个运动员的最大努力，因此梳理短跑峰值的表现优势仍然具有挑战性。考虑到优秀短跑运动员之间生物力学变量的差异，建议通过单受试者分析来研究冲刺冲刺的表现(Bezodis et al.， 2014)。

The running related injury rate has been reported as high as 37%-56% and keeps consistent to recently years (Mechelen et al. 1992; Messier et al. 2018). Although multifactorial factors can increase the risk of running related injuries, impact-related ground reaction force (GRF) variables, which include peak value of vertical GRF, vertical loading rate, may play a key role in the cause of injury. (Messier et al. 2018; Caleb et al. 2020). Accordingly, the use of cushioned or shock-absorbing shoes has been suggested since these shoes may reduce the impact forces during running (Rome et al. 2008). However, the effectiveness of shoes in reducing impact force remains controversial in the literature. Recently, highly cushioned shoes with a carbonfiber plate have received increasing attention from scholars and practitioners. This new advanced running shoes may dramatically reduce the impact force and the vertical impact peak may be visually absent in the time-domain. However, a study showed that although a distinctive vertical impact peak may not be visible, frequencies representative of a significant vertical impact are present. (Gruber et al. 2017). Therefore, it remains a question if the highly cushioned shoes could change the frequency content of the GRF when the vertical impact peak is not visible in the time domain. Purpose of the study

Metabolic cost and muscle fatigue are important and interrelated criteria that influence running performance. Runners incur a greater metabolic cost when running with fatigued lower limb muscles (induced by an exhaustive bout of running) than when running with unfatigued muscles (Nicol et al., 2007). However, it remains unclear how individual muscle groups contribute to the observed metabolic penalties. Of particular interest are the knee extensors (KE), due to their large volume and important role in locomotion. Because midsole cushioning and KE behaviour can both affect impact attenuation during running, shoe design may influence the relationship between metabolic cost and KE fatigue. Unfortunately, the relationship between metabolic cost and KE fatigue is not yet well understood.

Typically, competitive and recreational runners can be differentiate based on their performance and running experience (Clermont et al., 2019). However, less distinction could be made with regards to the subgroups in recreational runners. This is because their running experience, performance and even their training activity are varied and largely different between one another. Identification of the subgroups in recreational runners is important to help identify their specific needs, for example the right training for each subgroups. In addition, the aspect of shoes selection could also benefits from this segmentation in recreational runners. For many runners, subjective characteristics such as shoes fitting and a much specific parameter such as the mechanical characteristics of the shoes, namely the cushioning and shock absorbency performance, are important in finding suitable shoes. It is still unclear if these preference of shoes characteristics are different in between subgroups of recreational runners.

The modernisation of cushioning materials has led to increasing midsole stack height while minimally compromising the mass of the running footwear. Some have argued that increased midsole stack height itself may improve running performance (Burns & Tam, 2020), citing work on effective leg length across terrestrial animals (Pontzer, 2007). However, despite having governing bodies implementing limitations to this aspect of footwear construction, the isolated effect of increasing midsole thickness is not well understood.

Thirty-four male participants performed a rapid change of direction cutting task at maximal effort wearing the same footwear conditions (Nike Vapour Edge Speed 360) on an infilled artificial turf surface (FieldTurf Inc.). The task consisted of the participant sprinting towards the force platform, performing a 180 turn and then sprinting away from the force platform as quickly as possible. The artificial turf surface was constructed with a low carpet fibre faceweight (reduced number of fibres) compared to a conventional surface, allowing for increased infill movement, and providing a surface that reduced traction and fostered footwear slippage. A motion capture system (240Hz) and force platform (2400Hz) were used to quantify the movement/orientation of the shoe and the forces generated during the change of direction movement. All trials were classified into one of three categories based on the horizontal displacement of the forefoot during the stance phase of the change in direction: (i) stick, which represented the lowest movement (25% of trials), (ii) standard, which represented the average movement (50% of trials), and (iii) slip, which represented the highest movement (25% of trials). Biomechanical data was then statistically compared to the Standard condition using a paired t-test (alpha 1⁄4 0.05).
