What term describes the movement of turning the sole of the foot inward?

The term that describes the movement of turning the sole of the foot inward is "inversion." This movement occurs when the foot's medial side lifts and the lateral side lowers, resulting in the sole facing towards the midline of the body. Inversion is commonly observed in actions like walking, running, or standing, where the foot rolls inward.

Understanding this term is crucial in sports medicine, especially when assessing injuries related to ankle sprains or other foot-related conditions, as excessive or improper inversion can lead to injuries. The term "eversion," which describes the movement of turning the sole outward away from the midline, is often confused with inversion but represents the opposite motion. Supination involves a combination of inversion and plantarflexion, whereas pronation involves eversion and dorsiflexion, clarifying the directional movements of the foot and ankle.
