Calcaneal inversion/eversion is the frontal-plane component of rearfoot (subtalar) pronation and supination, not talocrural motion. Approximate stance values; swing angles are not shown.

Learning objectives

Follow rearfoot inversion and eversion — the calcaneus relative to the lower leg — through one walking cycle.
