podiatrist will and should have an arsenal of cracked heel lotions and potions in his/her arsenal. Some are scripts, and are often not cheap...but they work! ASK, ideally for the script and samples to see if you like the stuff and do the mail in thing! I speak from experience here.

Carmol and Keralac are the two main ones, most contain either salacylic acid or urea and I have to warn, you, wash your hands after applying and wear socks while it's on, or flip-flops as the stuff WILL dissolve shoe leather and furniture finishes! Yep, strong stuff! But getting open sores on your feet is a very undesirable option! - j
