Helps dry, cracked feet
Flavor Name: XL silicone socks 2 pairs
We use these on my husband’s cracked feet in the winter and put on a thick cream under these socks. They are nice because hair, dirt and that kind of stuff doesn’t stick to the outside. I do wish them came in more sizes and colors. They were a little small for my husband, but still worked good enough. My husband isn’t thrilled about wearing pink socks around the house. At least it’s just around the house and not out in public though.

Be aware! Once they are on, do not walk! 😂
Flavor Name: XL silicone socks 2 pairs
I absolutely love these things. But the first time I put them on in the living room. The walk to my bedroom was VERY interesting 😂😂😂 I now know I need to put them on and hang out for a bit, or simply go to bed. They do exactly what I need them to do. Feet feel great afterwards! With the right lotion, only need to use one every couple of weeks.

Transformed my feet
Flavor Name: XL silicone socks 2 pairs
After trying several other brands that actually my size did not have the luxury feeling of these. T although x large they have the BEST feel and function. I put lotion on then slip them on and within a few minutes my dry cracked heals are soft. Really a nice product.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.
