The heelbone, also known as the calcaneus, is the bone at the back of your foot that forms your heel. It's the largest bone in your foot and plays a crucial role in supporting your weight and allowing you to walk, run, and jump. Think of it as the foundation of your foot's architecture. It connects to the Achilles tendon, which is essential for moving your foot and ankle. Injuries to the heelbone can make it difficult to perform everyday activities. So, treat your heelbone with care!
