Altrac-tain by Sween. It contains 10% Urea and 4% AHA. No more cracked heels. I rub a little on my heels daily and they are great now for sandals. I have given some to my Mom, SIL and Mom's friend and they all swear by it. Ordered it the other day from their site on line...free shipping and no tax to MS. I also use their Baza cream for rashes and microguard powder daily (both have 2% miconozole).
