I could not agree any more. These are hands down the best socks I've ever worn. I was leery paying the high price for them, but after my first pair I bought two more. I now have a couple of pairs for cold, a couple for warm. I was unaware of the warranty until now, but that makes me want to buy a couple more pairs knowing that it's the last purchase I'll ever need to make for my socks. So darned comfortable, they don't slide down my legs, thick enough to protect, thin enough to breathe. I highly recommend.
