Heel fissures can be prevented by wearing properly-fitting, supportive, cushioned footwear, as well as heel inserts, both of which protect the heel’s fat pad from wearing down. Avoid wearing sandals and open-heeled footwear that expose the heel and provide less support to the area. Keep the heel’s skin moisturized and soft; uses pumice stones or foot files to get rid of calluses so fissures don’t form in the thickened, dry skin. Podiatrists have treatments for heel fissures and calluses. Always see a doctor for deeper heel fissures that can lead to infection.
