Eversion refers to the movement of the foot in which it rotates outward away from the midline of the body. This movement primarily involves the subtalar joint, which is located between the talus and calcaneus bones in the foot. During eversion, the lateral aspect of the foot rises while the medial aspect lowers, effectively positioning the sole to face outward. This action is crucial in activities such as walking and running, as it helps to adapt to uneven surfaces and maintain balance.

In contrast, other options describe different movements. For instance, the first choice discusses inversion, where the foot moves inward toward the midline, while the third choice describes a static position without any movement. The fourth choice refers to a forward linear motion typically associated with flexion rather than eversion. Therefore, the accurate definition of eversion aligns with the designation of the foot moving outward away from the midline of the body.
