A marvel of bioengineering, the human foot combines the mechanical complexity of a Swiss watch with the structural strength of a cantilever bridge.
The largest and strongest tendon of the foot is the Achilles tendon, which extends from the calf muscle of the leg to the heel.
The phalanges are connected to the metatarsals by five metatarsal phalangeal joints at the ball of the foot.
A structural flaw or malfunction in any one part can result in the development of problems elsewhere in the body.

Collectively, the forefoot bears half the body's weight and balances pressure on the ball of the foot. The midfoot, featuring five irregularly shaped tarsal bones, forms the foot's characteristic arch and serves as a shock absorber. The top of the talus is connected to the two long bones of the lower leg, the tibia and fibula, forming a hinge that allows the foot to move up and down. It joins the talus to form the subtalar joint, which enables the foot to rotate at the ankle.

They give the foot its shape by holding the bones in position, and expand and contract to impart movement to the bones and joints.
