Originally had a little dry edge at around the very end of the heels due to wearing sandals in a dry climate. Lotion helped but decided to try Ped Egg . BIG mistake. Now have a much larger area on the heels that feels like sandpaper. The only way to get rid of it was to keep using the egg, so heels were either raw from scraping or calloused and rough. Vicious cycle. Threw the Egg away, and now trying to find something to get my feet back to how they were originally. Terrible product; stay away. read full review »
