Calcaneus

The calcaneus, commonly known as the heel bone, is the largest bone in the foot that forms the foundation of the heel. It supports your weight when standing, walking, or running, and provides attachment points for muscles and tendons that enable foot movements. The calcaneus also helps absorb the impact of your steps, protecting other bones and joints. Its sturdy structure is essential for proper balance and mobility, making it a critical component of foot anatomy and function.
