All my life I've worn white cotton socks, mostly FOCL or Hanes. I've never worn black socks before. Since I buy Puma sneakers, I decided to buy Puma socks as well, that's all. I wasn't expecting much at all, but how will you know if you don't try? When I put these socks on for the first time, it was the best feeling my feet have ever had. The material stretches and once your foot is in it hugs your feet and feels very comfortable. I would also like to have mittens made of this material. The socks have been through several washes and are still like new with no signs of wear. Absolutely great socks. Couldn't be happier.
