About
Morton’s Foot describes a structural variation in which the first metatarsal is shorter than the second metatarsal. This alters how forces are distributed across the forefoot, often shifting load toward the second metatarsal during stance and gait.
Because the first ray plays a key role in propulsion, a shorter first metatarsal may reduce its ability to effectively bear load during push-off. This can influence overall foot mechanics and contribute to compensatory patterns in the forefoot.
Effect of Deviation
A shortened first metatarsal may increase loading under the second metatarsal and alter propulsion efficiency, contributing to forefoot stress and compensatory mechanics.
