A twisting motion of the foot that turns the sole of the foot outward is called what?

The twisting motion of the foot that turns the sole outward is referred to as eversion. In this movement, the foot rotates away from the midline of the body, causing the lateral side of the foot to lift and the sole to face outward. This action is crucial for various activities that require balance and stability on uneven surfaces.

Understanding the context of foot movements is essential. For example, supination is the opposite motion, where the sole turns inward and the foot rolls towards the midline. Inversion describes the movement where the sole turns inward, while the term "pronated position" generally refers to a position where the body is facing downwards or where the foot is in a position that increases the arch.

Thus, eversion appropriately describes the movement of the foot turning outward, making it the correct answer in this context.
