These are probably the worst socks I have bought. They have an un-natural feel to them on your feet and just straight nasty feeling by the end of the day. I have to wash them twice on hot with tons of soap and they still feel dirty. They don't keep your feet worm even with regular everyday boots. They don't stay up on your leg. Don't buy these socks. Just spend the extra money and buy the Burton or Smartwool, something with Merino wool. I should probably send them back, but it's not worth my time.
