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 foot muscles stiffen the metatarsophalangeal joint during the propulsive phase of jumping. This increases the external moment arm of the ground reaction force and increases plantar flexor force production (Smith et al., 2022) and may explain the increased vertical heights (Yamauchi & Koyama, 2020) and horizontal jump distances (Goldmann et al., 2013) associated with foot strength. Previous foot training interventions that improved jump performance mostly utilised specific toe flexor strengthening exercises. The short foot exercise (SFE) requires no equipment and involves raising the medial longitudinal arch by drawing in the metatarsal heads which target the intrinsic foot muscles (Gooding et al., 2016). Yet, the effect on jump performance is unknown. Moreover, previous foot training interventions have not considered the effect of footwear on jump performance. Footwear stiffness has been shown to enhance jump height (Lam et al., 2018), but may diminish the effect of stronger foot muscles.
在跳跃的推进阶段，足部肌肉使跖趾关节变硬。这增加了地面反力的外力臂，增加了足底屈肌力的产生(Smith et al.， 2022)，并可以解释与足部力量相关的垂直高度(Yamauchi & Koyama, 2020)和水平跳跃距离(Goldmann et al.， 2013)的增加。以前的足部训练干预，提高跳跃性能主要利用特定的脚趾屈肌加强练习。短足运动(SFE)不需要任何设备，通过拉伸针对足部内在肌肉的跖骨头来提高内侧纵弓(Gooding等人，2016)。然而，对跳跃性能的影响是未知的。此外，以前的足部训练干预并没有考虑到鞋类对跳跃表现的影响。鞋子的硬度已被证明可以提高跳跃高度(Lam等人，2018)，但可能会削弱更强壮的足部肌肉的效果。

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).

Tennis is an intense sport requiring multidirectional displacements and many acceleration-deceleration phases on the court. This results in large ground impacts up to 2.5 bodyweight together with a sagittal foot angle above 40 degrees (Herbaut et al., 2016). Such impacts localised on the heel generate large loading rate and peak pressure which may cause acute or overuse injuries, even more when the player wears improper shoes. Shoe heel geometry can have an influence on impact characteristics. For instance, a flattened heel geometry induces a larger impact loading rate in badminton lunges when compared to a rounded heel geometry (Lam et al., 2017). Yet the optimal curvature of the rear part of the shoe remains unknown in order to minimise impact parameters such as the loading rate.

Engineering innovation and material science have arguably revolutionized the footwear-distance running performance relationship in the last half decade. The newly designed, thick-soled, distance racing shoes have substantially reduced the chemical energy that running requires. Because endurance performance directly depends on energy supply and demand, reductions in demand elevate the racing speeds possible on the body’s limited supply of aerobic energy. Equivalently novel footwear designs have also come forth for the sprint running events. The new designs have several features (including soft and resilient cushioning) that could influence sprinting mechanics and performance. Because speed maintenance is extremely sensitive to step numbers and the total time of foot-ground contact (Bundle & Weyand, 2012; McClelland & Weyand, 2022), the novel designs could induce gait timing alterations that improve performance.

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.

Biomechanics research can have limited direct application to the clinical world because of specialized, expensive equipment that requires trained personnel to operate. The Loadsol is a wireless insole device used to measure vertical ground reaction force (GRF) and fills a need for measuring force in a clinical setting at a lower cost. The reliability of the Loadsol during running has been published (Seiberl et al., 2018), but there is no current literature regarding reliability in cycling. Cycling has been clinically prescribed during lower limb rehabilitation protocols, osteoarthritis prevention and symptom management as a result of decreased knee loading for patients (Kutzner et al., 2012). Therefore, the reliability and validity of the Loadsol during cycling when compared to 3D force sensing pedals are important and has not been addressed.

Curved carbon fiber plates have demonstrated metabolic and performance benefits in distance running shoes (Hoogkamer et al. 2018). The purpose of this series of studies was to evaluate whether curved plates specifically designed for women’s walking shoes provided benefits during walking. We hypothesized that a contoured plate would reduce range of motion and work at the metatarsophalangeal (MTP) joint without increasing the ankle plantarflexion moment during walking. Further, we hypothesized that these biomechanical benefits would translate to perceivable benefits after all day use.

The sliding motion in tennis caused by proper friction of tennis shoes enables quick change of direction (Pavailler & Horvais, 2014) and reduces the load on the joints (Damm et al., 2014). Accordingly, tennis shoe manufacturers are changing the design of the outsole pattern so that the intentional sliding motion appears. However, there is a lack of accurate criteria or data in designing the level and direction of friction for the pattern of the outsole of tennis shoes.
