Effects of different custom orthopedic insoles on kinematics of rear-foot in patients with high-arched and shin splints during toe-off

Shin splints are common in high-arched runners, which may be related to rear-foot over-supination during toe-off caused by forefoot eversion. It was reported that the forefoot lateral wedge insole could decrease the supination angle of the rear-foot during toe-off. The purpose of this study was to compare rear-foot kinematics characteristics between high-arched and normal foot runners, and find more suitable custom orthopaedic insoles for high-arched to prevent shin splints in three insoles. The results showed that the arch support adds forefoot lateral wedge insole(AS+FW) could not decrease the supination angle of rear-foot, but the arch support insole(AS) and the forefoot lateral wedge insole(FW) could prevent shin splints in the high-arch.
