Very good company to deal with and the product I ordered was beyond excellent. I purchased the Dachstein THREE PLY Knee Sock. I did not expect much from these socks as heavy wool socks I had worn in the past (like the type you would wear in a pair of chest waders) were rather like foot bags. These socks are a proper sock and fit my feet perfectly and have kept my feet warm for hours in the snow in a pair of Kennetrek hiking boots; a first. These socks perform better tan my Kuiu Ultra Marino and my Icebreaker Mountaineering wool socks and they don't fall down. I have also discovered why my Icebreakers make my calves itch so bad after a day of wear; they compress my lower leg like a normal sock with synthetic stretch fibers. With these socks my lower leg does not itch at the end of the day because they do not compress my leg and do not migrate down my leg either. These socks are truly fantastic.
