It runs from the tuberosity of the calcaneus (heel bone) forward to the heads of the metatarsal bones (the bone between each toe and the bones of the mid-foot). </P> <P> The plantar fascia is a broad structure that spans between the medial calcaneal tubercle and the proximal phalanges of the toes . Recent studies suggest that the plantar fascia is actually an aponeurosis rather than true fascia . The Dorland's Medical Dictionary defines an aponeurosis as: (i) a white, flattened or ribbon - like tendinous expansion, serving mainly to connect a muscle with the parts that it moves, (ii) a term formerly applied to certain fasciae . Further, it defines the plantar aponeurosis as bands of fibrous connective tissue radiating toward the bases of the toes from the medial process of the tuber calcanei (posterior half of the calcaneus). </P>
