A must for the summer
Color: Mellow Moon
I was a bit skeptical about these after seeing on tik toc, but they really work. I have not had a pedicure in months and with these my feet remain smooth.

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.
