The feet are flexible structures of bones, joints, muscles, and soft tissues that let us stand upright and perform activities like walking, running, and jumping. The feet are divided into three sections: The forefoot contains the five toes phalanges and the five longer bones metatarsals. The midfoot is a pyramid-like collection of bones that form the arches of the feet. These include the three cuneiform bones, the cuboid bone, and the navicular bone. The hindfoot forms the heel and ankle. The talus bone supports the leg bones tibia and fibula, forming the ankle. The calcaneus heel bone is the largest bone in the foot. Muscles, tendons, and ligaments run along the surfaces of the feet, allowing the complex movements needed for motion and balance. The Achilles tendon connects the heel to the calf muscle and is essential for running, jumping, and standing on the toes.
