Stains easily. Tight for men's size 11 feet
Flavor Name: XL silicone socks 2 pairs, Flavor Name: XL silicone socks 2 pairs
Husband wore dark cotton socks over these gel foot covers overnight and the covers picked up color from the socks. Tried hand washing, even dabbing with a bleach soaked paper towel, but the stains remained. The covers are a bit tight for men's size 11. Edit: After a few more hand washings the stains began to fade. However one tore around the leg opening when taking it off.

Worthless. Tore on first use.
Flavor Name: XL silicone socks 2 pairs
The first time I put these on my feet, the whole toe broke right through. They were a proper fit and my feet are well pedicured. Just very poor quality. I don’t recommend.

Best fit!
Flavor Name: XL silicone socks 2 pairs
Search no further, these are the BEST! They are smazing at conforming to the shape of your feet. They fit snuggly with no sags/bags or uncomfortable pressure or squeezing of your toes.

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.
