Parametric design of insole for different foot arch types by finite element method

Arch morphology significantly affects plantar pressure distribution and load-bearing balance, and appropriate insole support can improve plantar load distribution. This study developed insoles for high- and lowarched feet by varying the medial-lateral arch height difference. Finite element analysis was performed to evaluate peak plantar pressure and plantar contact area. The optimal designs were identified as (-10, 5 mm) for high-arched feet and (-10, 0 mm) for low-arched feet. These findings provide a preliminary basis for the parametric design of arch-specific insoles and personalized orthotic insole design under static standing conditions.
