Can your particular way of walking cause you fracture your heel over time?

Stress fracture. Repetitive stress to the calcaneus (heel) bone can cause a stress fracture. The stress can be caused by a certain activity, gait, and/or change in shoewear.
Probably not. The calcaneus, or heel bone, can develop a stress fracture, which is an overuse injury. It occurs when muscles become fatigued and are unable to absorb added shock. Eventually, the fatigued muscle transfers the overload of stress to the bone causing a tiny crack called a stress fracture. It would be hard to implicate a particular way of walking as leading to a stress fracture of the heel.
