This sock is incredible! First of all, it comes in two sizes so it fits much better than a one size fits most! Secondly, the arch support in amazing! I have NEVER worn a sock that I can feel the support without cutting off the circulation in my foot. Lastly, it is truly odor free! I was a sock Buyer for the top retailer in the US and I have tried several different socks. These are by far the best I've ever worn! You will not be disappointed in these socks!
