Pronation is a natural movement of the foot that occurs during foot landing while running or walking. Composed of three cardinal plane components: subtalar eversion, ankle dorsiflexion, and forefoot abduction,[1][2] these three distinct motions of the foot occur simultaneously during the pronation phase.[3] Pronation is a normal, desirable, and necessary component of the gait cycle.[4] Pronation is the first half of the stance phase, whereas supination starts the propulsive phase as the heel begins to lift off the ground.[5]
