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.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S64 - S65"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47880362","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}

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.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S113 - S114"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42774922","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}

Some footwear properties, such as midsole cushioning, have been shown to alter peak plantar pressures in the midfoot, metatarsal and toe regions (Wiegerinck et al., 2009), which may influence the risk of running-related foot injuries (e.g., stress fractures and plantar heel pain). Along with midsole cushioning, a key component of advanced footwear technology is the increase in longitudinal bending stiffness (LBS) with an embedded carbon fibre plate (Ortega, 2021). Running in footwear with increased LBS from a carbon fibre plate has been associated with an increased risk of bone stress injuries (Tenforde, 2023), but the mechanisms behind this relationship are not fully understood. Therefore, measuring plantar pressure distributions while running in footwear with increased LBS can help us better understand the influence of carbon fibre plated shoes on performance and injury.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S193 - S195"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46896427","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}

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.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S120 - S121"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42909326","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}

Iwai","doi":"10.1080/19424280.2023.2199403","DOIUrl":"https://doi.org/10.1080/19424280.2023.2199403","url":null,"abstract":"Falls in everyday life can cause serious disability or death especially in older people. Recently, the need for safety against falls has increased, thus shoes are required to have high slip resistance, even on wet surfaces with water or oil. On a smooth surface, most of the friction is adhesive. Adhesion friction is caused by adhesion at the interface where the shoe sole and the road surface are in contact each other. When the surface is wetted with water or oil, the total frictional force is greatly reduced because the contact area is reduced by the intervening liquid film, thereby reducing the adhesive friction. The tread pattern of the shoe sole forms grooves which allow water to escape and promote contact between the shoe sole and the road surface. Therefore, the design of the sole tread pattern has a significant effect on slip resistance on smooth surfaces. The purpose of this study is to evaluate the tread pattern and develop a new tread pattern by observing the sliding state simply under lubrication using specimens that simulate the tread pattern of a shoe sole. The coefficient of friction was acquired by traction tests, and at the same time, visualization of fluid flow by PIV (Particle Image Velocimetry) was attempted. PIV is a method of visualizing fluid flow by tracking the motion of particles dispersed in the fluid.","PeriodicalId":45905,"journal":{"name":"Footwear Science","volume":"15 1","pages":"S140 - S141"},"PeriodicalIF":3.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48926384","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}

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.
