Warm wool socks that don’t itch. Using a terrycloth weave of 100% Merino wool, these socks are blister-proof, machine washable, and come in four thicknesses, from a very light liner, to a heavy mountaineering sock. I use the Light or Hiker styles, which give incredible comfort with no feet moisture. They stand up to wear and repeated washing amazingly well. I haven’t had a blister yet, even with new boots. And they really don’t itch. Well worth the extra dollars.
