Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

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!
