Cracked heels are most often caused by a lack of
moisture in the skin. Fissures generally occur on the
back of the heel and usually affect both feet. For
most people cracked heels are a cosmetic problem
only, however, fissures can become problematic
if they deepen and cause pain, and in some cases
infection will develop. Topical products, e.g. ureabased
creams, are used to both prevent and treat
cracked heels.
