This study aims to compare the effects of hip-based and knee-based exercise interventions on medial longitudinal arch height, dynamic balance, and lower limb muscle strength in individuals with flexible flat feet. Participants will be randomly assigned to two groups: one receiving hip-focused strengthening and stretching exercises, and the other receiving knee-focused exercises, while both groups will perform a common set of foot intrinsic exercises. The intervention will be conducted over 6 weeks. Outcomes will be measured pre- and post- intervention and in the middle of intervention to determine which approach is more effective in improving foot stability and functional performance.
