Awesome but loses shape
Color: Long Black, Size: 10-13
This is comfy and keeps my feet warm but definitely doesn't hold shape good to wear indoors but don't think about walking long distances.

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.
