See What the World is Saying About Smartwool

"These cozy Merino wool socks are the perfect pair for colder, wetter days. They take everything we love about the natural material when used in hiking socks—it's thermoregulating, moisture-wicking, and sustainable—but slim down the design for a more active workout... the front-venting design keeps them from roasting your feet as you get further into your workout."

"Both men’s and women’s versions use Indestructawool technology that creates a thin fabric with impressive durability. There is minimal added cushioning in these socks which have a comfortably snug fit, with mesh ventilation zones for moisture management and breathability, plus an elasticized flex zone at the ankle joint to further stabilize the fit. These are the thinnest socks in our test group, but have held up very well to high mileage so far."

"It was just enough for absorbing impact when we hiked longer than a few miles but not so much that we found ourselves overheating. The sock always felt dry when we took it off, too. We credit our comfort to the mostly Merino fabric blend and the mesh ventilation zone at the top of the foot. Moderate compression and a tailored, gender-specific fit (the women’s version is slimmer with a narrower heel) kept the sock securely in place and prevented any slipping."

"This season, Smartwool updated the style for women. The Smartwool Pro Endurance Sock ($26) is made with a blend of 49% merino wool, 44% nylon, 4% elastane, and 3% polyester. This gives the sock a little bit of everything you need: stretch, targeted ankle and sole cushion, durability, and, of course, the venting properties of wool."

"And no other wool brand beats Smartwool. The company really hit it out of the base layer park with their Merino 250 Base Layer One Piece—a onesie (with an all-important drop seat) made from performance wool that wicks away sweat, is never itchy on skin, and is warmer than (much) thicker base layers that I’ve given a go in the past."

"One major drawback of no-show socks is the lack of warmth they provide. But these babies by Smartwool have all the benefits of warm, Merino wool mixed with the "barely there" coverage of a low-cut sock. The best of both worlds, truly."
