Biomechanics of the foot: pronation and supination

The key movements of the ankle joint include plantar flexion and dorsiflexion (in the sagittal plane), abduction and adduction (in the transverse plane), and inversion and eversion (in the frontal plane). Combinations of these movements result in three-dimensional motions known as pronation and supination. Pronation is a triplane movement combining eversion, abduction, and dorsiflexion. This combination causes the sole to face laterally. Supination is an opposing movement that combines inversion, adduction, and plantar flexion, causing the sole to face medially.
