Incredibly warm and comfortable

    Have two pairs of these socks and wore them interchangeably on a 14 day expedition in Antarctica. These socks are the best ones I own - they are comfortable, stay in place, are incredibly warm, do not retain odor, and will dry out pretty quickly for such a thick sock. Would recommend them to anyone doing high altitude or extreme cold temperature activities.

    These are the bomb

      Worth the cash (I bought two pair). I get cold feet and these things keep them toasty. Like John said below, you may want to take your shoe/boot size into consideration with these socks. They are THICK. My La Sportiva Glaciers still fit (they are my normal shoe size), but the fit is fairly tight. If you are buying new boots, I would buy these socks, and take them with you to try on boots. You may have to go up a half size or more over normal (that is common since you're planning to wear thicker socks). I also bought the white liner hiking socks for a liner. Bottom line, I love em!

      Holy Fat Cow

        These socks are so thick and plush and soft and warm that your feet will melt and fall in love.

        I own mountaineering socks from Darn Tough (longest lasting) Smartwool (cheapest) and another few pairs I don't remember the names of - These socks kick all their asses combined.

        Now for the bad news... they really are monstrously THICK and your boots may not fit you anymore unless you pullout your insoles.

        Buy It Now

          These socks are fantastic. They were the answer to the many prayers from atop my cold, windy deer stand. I did not have to layer with these like I had to do with other socks. Just one pair kept my feet toasty, dry, and comfortable. They are the softest sock I have ever worn, they have unmatched warmth, and I foresee them lasting me a very, very long time. They are another item typical of the quality I have come to expect from Patagonia.

          *Make sure to check the sizing chart before you order. They run true to size, but you don't want to end up with more or less sock than you need.

          Cozy at night

            Really nice and warm, even in wet, cold conditions of the mountains of Southeast Alaska. I kept these in my sleeping bag most of the expedition, and were something to look forward to after a cold wet day. When I did use them during the day, they kept my feet warm compared to other socks, but how warm can you get when you're constantly standing, sitting, walking. climbing, etc. on snow.


              i have several pairs of nifty and fancy socks...columbia, smartwool, etc..THESE take the cake. SUPER comfy...super thick and WARM! unbelievable how much snow got into my boots and these kept my feet warm! i cant tell ya enough how you should invest in a pair of these! i think they'll last a thousand years.

              Heavyweight socks

                I bought these socks for my husband. He loves them! They are pricey but his feet are worth it. He wore them all day in the cold and snow and his feet stayed warm all day. They are also cushiony and keep the odor and sweat down!! I couldn't ask for more!!

                warm sock with lots of cushion

                  This is a warm heavy-duty sock that provides good cushion for long trips. It has slightly more cushion than the SmartWool Mountaineering Xtra Heavy Mid-Calf socks (thought the difference was not highly noticeable for me). It also has a more snug fit than the SmartWool socks. These socks would most likely be better for someone with smaller feet than the SmartWool socks, but possibly too snug for someone with larger feet or calves.

                  Planning a 7-day trip in March on the AT...

                  Planning a 7-day trip in March on the AT through Smokies from Fontana Lake to Davenport Gap. Will these keep my feet dry as well as warm?

                  Best Answer

                  I think getting these socks for that specific trip is a tad extreme. You can easily get away with some Smartwool running/hiking socks. I personally love the Smartwool Adrenaline sock line, particularly:


                  I'd personally recommend getting a few pair of those and some trail runner shoes, but everyone has their own hiking style. I've done most of the AT in the Smokies, along with many of the side trails there... beautiful area! Enjoy!
