Smart Wool socks are nice, but IMO the Thorlo "Mountaineering" socks are better. I have both, but the Mountaineering socks you can pull all the way up to your calves and they will stay up on your calves. I hate the feel of a leather boot against my bare skin, and this is just what happens when i wear the smart wool. I say the Thorlos at Sportsman's Warehouse...I'm making my way out there right now...tata for now.
Oh, and it is just a few dollars more for the Thorlos.
