I used to have horrible dry, cracked heels - what a pain. I've used the Ped-Egg to remove skin build-up on my heels. The Ped-Egg has to be used when your feet are dry, never use it after showering. It takes a while for the Ped-Egg to show results, but as long as you're consistant with it, your heels will eventually be smooth. If you decide to use the Ped-Egg, don't place pressure on it, gently rub it back and forth. I also use the Gold Bond lotion, I apply it after I shower and before I go to bed. My heels have never looked better and they are super smooth now.
