The Effect of Customised Insoles on Performance in Athletes

This review study examined the effects of custom insoles on physical performance parameters in athletes. Insoles are customized according to the individual's foot morphology and biomechanical requirements to optimise plantar pressure distribution, improve lower extremity alignment, and reduce the load on the musculoskeletal system. The literature indicates that they have positive effects, particularly on sprinting, jumping, balance, and agility performance, and that they support energy efficiency and proprioceptive feedback mechanisms. Additionally, it has been reported that custom insoles have a protective effect against plantar stress and fatigue during prolonged activity, thereby enhancing performance sustainability. However, it is emphasised that they may not produce the same results in every individual and that insole design must be tailored to individual needs. Based on current findings, customised insoles are considered an effective orthotic intervention tool for improving sports performance and reducing the risk of injury. Future studies are recommended to examine the effects in more detail across different sports disciplines, surface conditions, and long-term use.
