<P> The tarsus articulates with the bones of the metatarsus, which in turn articulate with the proximal phalanges of the toes . The joint between the tibia and fibula above and the tarsus below is referred to as the ankle joint . </P> <P> In humans the largest bone in the tarsus is the calcaneus, which is the weight - bearing bone within the heel of the foot . </P> <P> The talus bone or ankle bone is connected superiorly to the two bones of the lower leg, the tibia and fibula, to form the ankle joint or talocrural joint; inferiorly, at the subtalar joint, to the calcaneus or heel bone . Together, the talus and calcaneus form the hindfoot . </P> <P> The five irregular bones of the midfoot--the cuboid, navicular, and three cuneiform bones--form the arches of the foot which serves as a shock absorber . The midfoot is connected to the hind - and forefoot by muscles and the plantar fascia . </P>
