Abstract Lower limb biomechanics of chronic ankle instability (CAI) individuals has been widely investigated, but few have evaluated the internal foot mechanics in CAI. This study bone and soft tissue stress CAI contrasted with copers non-injured participants during a cutting task. Integrating scanned 3D shapes free-form deformation, sixty-six personalized finite element models were developed. Computed Achilles tendon forces measured regional plantar pressure applied as boundary loading conditions for simulation. It was observed that primary group differences occurred midstance heel-off phases Specifically, healthy had significantly higher talus around compared to participants. In contrast, cuneiforms lateral forefoot bones mid-stance push-off phases. appeared adopt protective strategy by transferring greater force at phase while lowering talus, which may be associated pain relief near ankle. These findings suggest further attention should placed on implications long-term adaptation. Graphical
