heel

The heel is the back part of the foot, consisting of the calcaneus bone, which is the largest bone in the foot. It acts as a shock absorber during walking and running, helping to distribute body weight and provide stability. The heel also includes muscles, tendons, and fat pads that support movement and comfort. Proper heel function is essential for balanced gait and to prevent foot pain or injuries. Conditions like heel spurs, tendinitis, or plantar fasciitis can affect heel health, often caused by overuse, improper footwear, or biomechanical issues.
