Dry and cracking skin can be very uncomfortable and if left untreated, can lead to serious wounds on the foot. Cracking can be caused by bacteria, a lack of moisture in the skin, and/or can have a hereditary component. Shaving of the area yourself can often result in larger wounds that can lead to infection. Medication and creams are very effective in the treatment of dry and cracked skin. Skin care has progressed tremendously in the last ten years, so much so that cracked heels should be a thing of your past.
