I used to suffer terribly with chronic dry skin on my feet and painful cracked heels. I used to use a variety of heel balms and foot creams containing Urea, but had concerns about the safety of regularly using this on the skin. One day I saw Heel Chemistry in my local Chemist and decided to try it, even though it seemed quite pricey. I was not disappointed. After just a few days use my feet were looking and feeling better than they had in years. I now would not switch to anything else. My once unsightly feet can now wear sandals again!
