When feet get dry -- and we mean arid -- the heels can become cracked and may even develop fissures in severe cases. This super-dry skin is a condition known as xerosis. You're also upping your risk of cracked heels if your shoes don't fit properly -- anything that rubs on the heel can cause problems.
Aside from looking unpleasant, cracks and fissures in your heels pose a health concern if you don't treat them. They're an open invitation for bacteria to invade, causing potentially life-threatening infections. Regularly slathering on foot cream can help prevent -- and treat -- cracked heels.
