Two years ago I purchased Copper Fit socks when the material breakdown was 91% nylon and the product was sold two pairs per box for around $14.00. I was very satisfied with the compression, and the socks were very comfortable! But now the socks are made with only 84% nylon and do not stay up! They are now sold one pair per box at $10.00, but I will not recommend this product until they make them with 91% nylon. I have sent the company five emails with no response. Do not waste your money! Walmart has a better compression sock for around $19.99 a pair (ABD sport socks).
Bottom Line: No, I would not recommend this to a friend
