Arches of the Foot There are 3 main arches of the foot and are formed by the shape of the bones and supported by the soft tissues

Arches of the Foot

Arches of the Foot The Plantar Fascia is a tendinous structure from the calcaneus to the metatarsals and on to the phalanges It purpose is to maintain the arch of the mid-foot
