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 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 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 5 out of 5 by from Pamper your feet with these divine marshmallow feet-lovers!!! I got my boyfriend a pair of these socks for his birthday and he loves them! His old pair he wore so frequently that he wore right through the soles! They really love & pad the arches, heel, and everyplace, and there is plenty of cushion for the...feet. Also, the perfect pair of socks for the run and slide move on the hardwood floors Risky Business style. (BONUS--even though they are very well insulated, they do a great job of wicking away moisture so you never get that uncomfortable swamp-foot thing going on)

Rated 5 out of 5 by from If you love your toes, then you will love this sock! Let me start out by saying, these socks are THICK. They are very thick, but this is just what I needed. Since it can be quite cold above 13,000 ft these socks came in handy and I am very happy that I had them. I will not buy another brand of sock after having the pleasure of using these. One little piece of advice, get the Smart-wool liner socks and wear them under these. Let's do some math:,,,,Smartwool Mountaineering Sock + Smartwool Liner Sock = Warm and blister free feet!

Rated 5 out of 5 by from Best socks! My first impression when I touched the socks was really nice! They are extremely smooth to the touch, and it's more than important if you are going to walk for long distances. I've gone out to run using my new socks in a cold evening and my feet were really warm. The socks are pretty breathable as well! I'm sure that in high mountain they are going to work in the same way.,,The best thing: these socks are very warm and comfortable without being extremely thick. Recommended 100%

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 Super lofty super comfy I have one pair of these, they sometimes live in my sleeping bag because they are so incredibly warm. One step lower than bedroom slippers, I usually don't wear my pair with boots because I like the loft so much and won't risk having these socks be grimey. With feathered friends down booties, the ultimate in lightweight foot warmth. Fold your socks all the way in on themselves and they are very packable and they also serve double duty protecting precious gear when I travel.
