Healed cracked feet!
Color: Gray
These moisturizing heel socks are great for dry, cracked heels. They’re soft, comfortable, and easy to wear around the house or overnight. I like that the silicone/gel part helps lock in moisture, especially when paired with foot cream or lotion.
They fit well without feeling too tight, and having 4 pairs is really convenient. After using them consistently, my heels felt softer and smoother. Great little self-care item, especially if you’re on your feet a lot or struggle with dry skin.

Great stretch.
Color: Gray
My husband has diabetes and these work great on his heels.
I was worried they would be too small, he wears a size 12 shoe and they fit great!

Great
Color: Gray
I purchased these after having a total knee replacement. My heels were getting sore from the exercises. These little socks with the gel has helped tremendously. I am now sleeping in them. and the soreness is going away.
