Good progress after one month of use. I still have cracking in both heels, but they appear to be diminishing. I also have been using the product on calluses on the outer side of both big toes. It looks like those calluses are diminishing, but more slowly than the cracked heels. I should have a better idea for a full yes or no recommendation after another six weeks of use (or until current supply expires).
Bottom Line: Yes, I would recommend this to a friend
