This video is a gait analysis of one of my patients as she returns to running after rehabbing a metatarsal stress fracture. Supination is a natural part of the gait cycle, but excessive supination—where the foot consistently lands on the outer edge—can reduce shock absorption and increase injury risk. Efficient running relies on a smooth transition between supination and pronation to properly absorb and distribute impact forces: In sprinting, the foot typically lands on the forefoot or midfoot,
