I bought this socks with doubts if they will perform as stated, they are expensive and I didn’t know if it was really breathable (I sweat a lot in my feet), would prejudice my circulation or be quite durable. Now I’m very satisfied with them and maybe will buy some more to have more pairs in the closet. Also due to a particular situation had to contact them and noticed they are very kind people, I’m very pleased to buy with them.
