    • Merino wool/nylon/elastane blend
    • Lightweight
    • Light cushioning

    Scratchy and thin

    • Familiarity: I returned this product before using it

    I had some socks by Smartwool that looked just like these, but they were soft and comfy not scratchy and rough.

    10/10 running socks

    • Familiarity: I've put it through the wringer

    Purchased these when I was training for a half marathon and absolutely love them. Great cushioning that isn't too thick or sweaty. My go-to running socks!

    Love them

      Breathable and lightweight - and high quality! Keep your feet cool and dry.

      Best socks around

      • Familiarity: I've used it several times

      These sock are amazing! when you have a job on your feet all day you can never go wrong with smart wool

      Great socks

      • Familiarity: I've used it several times

      I love these stocks, they are super soft, comfortable to go to the gym, for hiking, traveling, long walks.

        Went back for more!

        • Familiarity: I've put it through the wringer

        I picked up two pairs of these and ended up going back for 8 more! The knit is nice and tight - they don't get stretched out with wear, even in a running shoe. I also use them in casual shoes because they are so comfortable. The merino blend wicks moisture away from my feet better than most socks I've tried. And they come in a great color variety!

        Karsyn, would you say these socks are good for 3 miles of running? My daughter’s feet sweats and I am looking for the right running socks.

        Wool blend ankle sock

        • Familiarity: I've used it once or twice and have initial impressions
        • Fit: Runs small
        • Size Bought: Large

        Runs small. Thin but cool in the summer and warm in the winter due to the wool. I bought the Large as I wear a 10 1/2 woman's but I needed a size Larger.
        So I gave them away.

        Nice leightweight socks

          Bought these for my wife. Now she wants 3 more. Washes well, and a small fits her size 5.5-6 shoe size

          Won't stay up!

          • Familiarity: I've used it several times
          • Size Bought: Medium

          Ugh, I love Smartwool socks, but these were a huge disappointment. They fall into my shoes within minutes, no matter which shoes I'm wearing. Maybe this pair sized small because the fit of my other SW socks is perfect. I like the thickness and color (pink!), but sadly, this pair is going to the thrift store. :(

          I love these socks

            These are the perfect socks. They are comfortable and durable and they stay on my heel!! I ordered one pair at first but I'm definitely going to get more.

            Great All Around Winter Sock

            • Familiarity: I've used it several times
            • Fit: True to size
            • Size Bought: Medium

            I bought this sock to wear running, at workout class, and to work (I like things that work in any setting!) I really like this sock - it is soft, comfortable, easy to wear. It is a little bit warm under sneakers on a warmer day, I'd go with something lighter if you're not looking for a winter sock.

            Fuzzy fast

            • Fit: True to size

            When I first put these on, the fit felt incredible! However, within the first wear, fuzz had formed all over the toe and heel of the sock -- BEFORE I had even washed the rocks. Already looking scuzzy within the first wear -- no bueno!
