A bony growth on the side of the heel, Haglund’s deformity is often the result of wearing hard, inflexible
shoes. Heredity has some infl uence, causing some to be predisposed to the condition. A person would be redisposed by having a large calcaneus (heel bone) or by walking on the outside of the heel. However, even with a predisposition to the condition, a person could likely prevent Haglund’s deformity by choosing shoes that do not put  pressure on the heel and the achilles.
