Great buy for rough heels
Color: Gray
These work great on hubby's feet which are always so dry. Just have to be consistent. They fit great and are comfortable he says.

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.
