Great Socks

    Really thin, but well padded. Still keeps the feet a little too hot though, would prefer it to be cooler.

    Socks socks socks socks socks, everybody

    • Familiarity: I've used it several times

    These are great moisture wicking socks so your feel always feel fresh. The lycra feels more snug than other merino socks I've tried, but it feels nice.

    Only socks I wear for training & racing

      After years of running in cotton golf socks a friend recommended I get some moisture wicking socks for an upcoming r2r2r run. These looked good so I bought a pair. I've since bought 5 more. I wore them in a ultra across the hot desert. I wear them every morning for training runs. And most recently I wore them on a 25k trail race where the first mile took us across a waist high river in 29 degree temps. These socks have performed flawlessly.

      Durable and comfy

      • Familiarity: I've used it several times

      I've gone through several of the thinner ultra light socks this summer but these seem like they'll hold up a bit better as the toe box is much thicker. I've run in these a few times without any problems and I've really enjoyed the extra padding that the ultra light version doesn't have. I wear a size 10 shoe and purchased the medium size.

      If it aint broke....

      • Familiarity: I've put it through the wringer

      Repeat buyer
      I love these socks! Just the right amount of material without being to thin or thick to the point of bunching up, having hot spots, etc.

      I prefer socks to be very snug, so I wear a medium, despite SW suggested sizing being closer to a large.

      I've also worn the ultralights, which I prefer in summer, but often my toes rip through the thin material (likely due to downsizing). I find the regular 'light' to be a good all-around compromise for year round activity.

      If you plan to run where there are sticky grasses, sticker bushes, etc., I'd recommend a low gaiter, as just a few of these can cause snags in the material and premature wear of the product.

      I'll definitely, continue to purchase these socks, though it remains to be seen if change in company ownership leads to changes in product quality, price, etc.

      Comfortable athletic sock

      • Familiarity: I've used it several times

      I use these socks for my athletic activities in and out of the gym. They don’t slip, breath well, and have a nice feel to them even after use.

      Perfect!

      • Familiarity: I've put it through the wringer

      Have a couple of these socks now and they always impress. Regulates your foot temperature well, they don't slip down, and they are naturally antimicrobial. All good things if you're wanting a great running sock.

      Comfortable and breathable

      • Familiarity: I've put it through the wringer

      These socks are something else, they offer the perfect amount of padding in the heel and toe areas to help prevent blisters on longer runs. Wool is naturally anti-microbial so they won't smell and offer the best temperature regulation so they'll breathe really well.

      • Familiarity: I gave it as a gift but have feedback to share

      Got as a gift, here is his review

      "If James Bond was a trail runner, he would use these. They stay dry where other socks do not, they are comfy and perform, they breathe and they are durable. Anything Smartwool rocks anyway so these are my go to running sock"
