What does "eversion" refer to in foot movement?

Eversion refers to the movement of the foot where the sole turns outward, away from the midline of the body. This action occurs at the subtalar joint, where the foot can tilt so that the inner (medial) edge of the foot lifts away from the ground. In practical terms, when one experiences eversion, the outer edge of the foot becomes closer to the ground while the inner edge rises. This movement is essential in activities such as walking on uneven surfaces, as it helps with stabilization and balance.

The other options describe different movements: inward facing (which would indicate inversion), upward movement of the toes (dorsiflexion), and rotation towards the body (which refers to ankle pronation). None of these define the movement of eversion accurately.
