Yaks smell, but your socks shouldn't.

SmartWool uses their long-lasting blend of wool and nylon to make their Trekking Heavy Crew Sock as adventurous as you are. The sights and sounds of an exotic land should not be overshadowed by the smell of your socks. Arch support and padding aid in keeping foot muscles relaxed and protected during long trips. Wool has the ability to keep your feet warm and dry while the outside temperature goes from chilly to steamy. Foot funk and odors are naturally repelled for day after day on the trail. Wash these wooly socks in a stream and they'll be dry before you know it.

Thick and toasty!

    I love these socks! I have several and they never disappoint. They are thick and they keep your feet dry and comfortable! Everything you need.

    Great heavy hiking sock

    • Familiarity: I've used it once or twice and have initial impressions

    Smartwool created a basic sock based on basic needs. If its too cold on your daily commute or hiking on the shoulder, slide this on for a comfortable and warm walk. Pair them with a silk liner for colder climates and you will be toasty all day!

        Comfortable and warm. Great for keeping feet warm while working outdoors in the cold temps. They are a thick sock, so can feel bulky inside shoes. Overall happy with the purchase.


          Use these socks often in winter. They are warm and will last many year.

          They just don't quit

            got size Large and I wear size 9 shoes and they are a good fit for sure.

            Used camping several times in cold desert trips and it performs great. Very warm. pretty bulky but that is to be expected.

            Ultimate holiday gift

            • Familiarity: I've put it through the wringer

            Everyone should own a pair of thick wool socks. These feel great to go to sleep in camping, and I can't go back to cotton generally after owning these.

            Everyone should have a pair

            • Familiarity: I've put it through the wringer

            Great socks, fit good and are true to all the manufactures claims.

            Worth the hype.

              Ok, wool socks? Sounds terrifying and itchy! Boy, am I glad I got over that attitude towards these socks. Listening to customers, and fellow Backpackers', I tested out a pair on a 10 day hike and couldn't believe I ever doubted the hype. I was just sad I only had one pair, which by the way I wore every single day. They kept my feet dry while regulating the temperature so they didn't overheat. Plus, wearing them every day in a pair of hiking boots, you'd think that they would smell right?! You're wrong. The Merino Wool actually neutralizes odor. So if you're looking for a sign you need these socks, this is it. Go ahead, test a pair.

              Warm and comfortable!

              Sweet Wool Socks

              • Familiarity: I've used it once or twice and have initial impressions

              Gave it as a gift, but feedback below:
              "Perfect wool socks. They are soft, stretchy, and do everything wool socks are supposed to do."

              Exactly what you want them to be

                These socks are perfect, they have extra cushion from the thickness yet they don't bunch up in your boot. These are my favorite heavy sock, you won't be disappointed!
