The foot can be compared to a finely tuned race car, or a space shuttle, vehicles whose function dictates their design and structure. And like them, the human foot is complex, containing within its relatively small size 26 bones (the two feet contain a quarter of all the bones in the body), 33 joints, and a network of more than 100 tendons, muscles, and ligaments, to say nothing of blood vessels and nerves.
