See What the World is Saying About Smartwool

"I found these socks offered light cushioning and great stretch (but not too much). They don’t slip or feel constrictive after a few hours in the saddle. The cycle crew socks have what the brand calls a performance-oriented fit, meaning seamless toes, “activity-specific” mesh zones for breathability, and Smartwool’s Indestructawool technology (the yarn and merino fibers are spun together in a way that makes the socks are more durable)."

"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."

"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."

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."
