    Trekking Heavy Crew Sock

    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.

    • Trail-ready socks for exploring wild parts of the world
    • Merino wool blend regulates temperature and manages moisture
    • Naturally odor-resistant to keep fabric fresh after wear
    • Heavyweight construction increases cushioning and warmth
    • Item #SWL0015

      I ordered 3 pair of heavy wool socks on 9-11-2019. They weren't shipped until 9-18-2019 with delivery expected on 9-25-2019. I received them today, 9-24-2019.
      I wear XL socks. 2 pair came in as XL and the Smart Wool socks came in as mens Small. It's too much trouble to send them back so I'll give them to a homeless midget.
      Not sure I'll order from here again.

      Great socks

      • Familiarity: I've put it through the wringer

      I have a lot of pairs of Smartwool trekking socks and I keep buying them because I love them. I use them for hiking, cross-country skiing, and just lounging. I have an old, almost worn-out pair that I use for sleeping.

      Had high expectations ...

      • Familiarity: I've used it several times

      These work well alone walking around my ranch house, which has concrete floors and is cold in the winter. I tried them alone with a goretex boot and wasn’t too impressed with moisture control but I think my expectations were set way too high. I don’t think any sock can do it all. I do really like them with smartwool hikeliner crew socks (thin smartwool liners). That seemed to make a huge difference in controlling moisture and feeling dry after long treks in cold weather. I’ll buy another pair, they are definitely worth the money. Love to sleep in them when it’s cold. Keeps my little piggies toasty!


      • Familiarity: I've put it through the wringer

      These socks meet the high quality standard expected from Smartwool. They keep your feet warm and don't start to stink after a long day of use. The small size was a good fit (typical shoe size 7.5 US). Only downside I see is that they become a bit less fluffy as you wear them, kind of matt together which might compromise a bit of insulation. Altogether, great socks though!

      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!

      Unanswered Question

      I wear a women's size 6.5 shoe. Would a small be too loose? I don't want to have extra fabric bunching up in my boots.

      Would these work well inside fishing waders...

      Would these work well inside fishing waders in the winter? I've had a few pairs of SmartWool in the past, but they have either shrunken up or gotten stretched out. I haven't found a pair that doesn't do one or the other. I need a pair for winter fishing as well as a pair for summer fishing with potential for a few miles and full days on my feet.

      Best Answer

      I would say ABSOLUTELY! These are great for staying warm and being on your feet all day. I have worn them on long winter hikes, as well as spring day hikes.

      For the past 4 months, I have only had 3 pairs of socks. One of them is the Heavy Trekking SmartWool. Even with constant use, I have not experienced any stretching. I hand wash and air dry all of my wool clothes to avoid shrinkage.

      Give them a shot!

      Would these socks be good to use in a three season mountaineering boot. Looking for a socks that will give me enough padding and support but not just roast my feet

      I have a pair of these.. but I only use them in the winter. They do have great padding and comfort, however I find them to be too warm from late Spring to early Fall. They are definitely too heavy and warm for the typical 3 season temps (40F-80F+).

      Are you going to be doing high altitude mountaineering?

      Best Answer


      I agree with Eli: they're a little warm for summer months. Check out the Icebreaker mid crew sock ( for something with a little (less) cushion that you won't cook in. I own a light crew pair and love them, and other reviewers have said they outlast smartwool by a longshot (and they're cheaper, to boot).

      Happy trails!

      The SmartWool Heavy Crew Trekking socks are a great choice for three seasons plus light to medium winter use. I always wear them with a silk or polypro liner. For cold winter activities, an insulated boot is your best insurance against cold feet plus a heavier sock. I wear a pair of boiled wool Dachsteins for snowshoeing. Here's more information:
