I very rarely leave reviews but had to for this. I have tried just about everything to repair my very dry/cracked heels. And this worked on the first use! I’ve tried every other cream, lotion, special socks, tools, etc, and this worked so well! I don’t know yet how each treatment lasts, but honestly my heels are softer than when I leave the nail salon. So even if I have to use this often, it already seems worth it. Definitely recommend.
