Which movement rotates the bottom of the foot medially?

• A. Dorsiflexion
• B. Inversion
• C. Plantarflexion
• D. Eversion

Answer: (B)

Inversion is the movement that rotates the bottom of the foot medially toward the midline. This happens mainly at the subtalar joint, turning the sole inward and slightly upward. Dorsiflexion and plantarflexion change the angle of the ankle in the sagittal plane—lifting the foot toward the shin and pointing the toes downward, respectively—without rotating the sole. Eversion, on the other hand, turns the sole outward, away from the midline.
