There is a total of 26 bones in the foot, creating a total of 30-40 joint articulations. Each of these have several supporting ligaments and tendons.

The two main joints in the foot are the sub talar and the mid-tarsal joints.

The mid-tarsal joint is primarily involved with inversion/eversion movements of the foot, with some motion in other planes.

The sub-talar joint is able to move in triplanar motion, and hence compensate for leg, hip and back anomalies through its ability to move in any direction and translate movement into the lower limb. Pronation and supination are such movements. The sub talar joint is the joint next distal to the ankle (talo-crural) joint. Its neutral or most stable and effective position can be palpated when the bony prominences of the talus are equally palpable on the lateral and medial aspects of the dorsal foot. It is the most important joint in the foot.
