Rated 5 out of 5 by from Great socks! I wanted to try these after wearing the Smartwool steel toe boot and uniform socks for a few years. ,,,,They're really well padded and comfortable, and don't develop any odors even after extended wearings. I'm on the high end of one of the size ranges and was concerned about the fit but I'd say follow the size chart, they'll fit fine and will stretch a bit if needed. ,,,,Curiously, even though they're so padded and thick they fit fine in my line boots, my mountain boots, my fire boots, and my uniform boots for what that's worth. ,,,,I plan to stock up on these for a lifetime supply in case they quit making 'em. While pricey these are really worth the cost. I highly recommend them.

Rated 5 out of 5 by from Save your wife buy buying these socks My wife has super cold feet at all times. Normally she copes with this problem by sticking her feet on my bare skin, which, is unpleasant at best... On one such occasion I was thrown from my bed in the middle of the night by a bolt of cold lightening on the middle of my back. The next morning I walked into Moosejaw and bought her these socks. Thanks Moosejaw for saving my marriage! and for making me look like thoughtful stud!

Rated 5 out of 5 by from Doesn't get any better than this!! Smartwool is known for their high quality, non-itchy wool products and their mountaineering sock is no different. This sock does a great job keeping feet warm and dry and when coupled with a Capilene liner sock, there's not a better system around. My sock drawer is overflowing with Smartwool socks of all kinds and I won't wear anything else. I just ordered another pair of these for myself and a pair for my old lady (it could be 90 degrees and she'd be saying her feet are cold!). Buy these socks for mountaineering use or wearing around the cabin and you will be impressed either way!

Rated 3 out of 5 by from Keeps you toes warm but they bunch up... I most recently wore them on a 4-day Mt Rainier trip in July. ,,,,My toes were nice and toasy the entire trip. HOWEVER... They have a tendency to buch up. Everyday I found myself with the heel of the sock around my achiles.,,,,I know what you are thinking... Yes, I bought the correct size for my shoe size and my plastic boots are also correctly sized.,,,,These socks would be perfect if Smartwool added some elastic around the arch support to keep them snug and in place.,,,,

Rated 5 out of 5 by from So Squishy and Warm, You'll Think Your Stepping on Oprah I bought these socks last winter as a respite from our cold floors in our old house. But, after the leaves fell and the snow began to come around, I put them on, under my hikers and went on an elevation gain hike. It was a little about 15 degrees that day, I was stomping in icy-mud, water, and deer poo, and I never had a moment of cold. They wicked fantastically, and were as soft a sock as I had EVER put on. They add so much to the support of the sole of the boots. And the are snug enough to prevent blistering. WARM WARM WARM. Smartwool, you've won over this Smartass.

Rated 4 out of 5 by from Warm sock This is the sock to have if you're going to be in cold weather. It seems that they fall a little bit with hiking, but not more so than other big-loft socks that I've tried. That said, for expedition use, they seem to stretch out a little more than other socks (e.g. Patagonia), so they do tend to fall more after you've been wearing them for a few weeks. For sure, I keep a pair in my sleeping bag as well for night time comfort when it is super-cold.

Rated 5 out of 5 by from Really warm! Picked these up to use in my drysuit while diving. My feet have never been warmer on an Ice dive then while wearing these. I cannot believe how warm my feed stay, even while wet they insulate very nice.
