2. It is formed by the calcaneus, talus, navicular, three cuneiforms and first three metatarsal bones.

SUPPORTING STRUCTURES
3. Muscular support: tibialis anterior and posterior, peroneus longus, FDL, flexor hallucis, and the intrinsic foot muscles (i.e. all muscles arising from the deep posterior compartment of the leg, peroneus longus & intrinsic foot muscles).
4. Ligamentous support: plantar ligaments (long & short plantar and plantar calcaneonavicular ligaments), medial/deltoid ligament of the ankle joint.
