Splits in the skin at the back of the heel are unattractive and can be painful. They are reasonably common, particularly in those who are predisposed to them. These types of cracks in the skin about the heel occur when the skin is thicker and dry. As the fat bad underneath the heel bulges out sideways when walking puts pressure on the skin that it may not take, so the skin just tears or splits. The wearing of open back shoes also plays a part in the condition. Some medical conditions may also contribute to the dryness of the skin and a number of different biomechanical problems contribute to the thickening of the skin.

Once a crack in the heel occurs, it does need to be treated as it may act as a entrance to have an infection to get in. First of all, an antiseptic should be used to prevent that if the split is open. It is next important to remove the thick callus around the peripheray of the heel. This can be carried out by a competent podiatrist for those who have access to podiatry. If not, you will want to use something like a foot file, pumice stone or emery board and get to work on reducing it. This tends to take a lot of work. When that thickened skin is removed, then it's vital that you use lotions and emollients to help make the skin soft and adaptable so it doesn't have the inclination to crack. Urea based lotions are generally much better for that. Once this original problem is dealt with, then preventative approaches have to be put in place to continue with or else the condition probably will happen again. Occasional use of a foot file or similar is recommended to keep the thick skin down and regular use of a urea based cream is crucial to make the skin resistant to cracking and prevent the dryness. Avoiding open back footwear is also suggested.
