The fascial layers within the foot have several functions and consist of interdigitating fibrous tissue. The main fascial layer is the plantar aponeurosis, which consists of medial, lateral, and central portions. Only the central section is truly aponeurotic. The origin of this tissue, at the medial process of the medial calcaneal tuberosity, is the site of the most common type of plantar fasciitis. The fascia may also be inflamed elsewhere along its length, when it is painful on stretching with dorsiflexion of the toes. The insertion of the fascia is partly via the superficial stratum that inserts into the dermis (under and distal to the metatarsophalangeal joints) and partly via the deep stratum that inserts into the plantar ligaments of the metatarsophalangeal joints, the flexor tendon sheaths, and the periosteal layer of the proximal phalanges.
