I have an adult granddaughter with several autoimmune diseases. She is a mom, and very tiny in size, so she wears a child size one shoe. I bought the socks for her, because she is constantly cold. I purchased one pair at Christmas to see if they were a good fit. She told me her children laughed at her for not ever taking them off. So I bought her two more.....I discovered Polar feet many years ago and they have never disappointed me.
