Feet are a flexible structure of bones that allow us to stand and balance but become rigid in order to allow propulsion.
The foot is made up of three sections:
The forefoot consists of the five toes or phalanges and the five long bones called metatarsals.
The mid foot is a pyramid structure consisting of the navicular, cuboid and three cuneiform bones.
The hind foot is the heel (calcaneous) and lower part of the ankle joint the talus bone.
The majority of the muscles which control the feet originate in the calf with long tendons reaching into the foot. The Achilles tendon attaches to the rear section of the calcaneous. The plantar fascia attaches from the base of the calcaneous and stretching forward to the far end of the metatarsals acting like a spring to improve efficiency of motion.
