Micro Crew Ultra-Lightweight Running Sock

Go-to coverage and blister-proof fit for competition level mileage and savage vertical gain. This favorite running sock is redesigned to be ultra-lightweight and perform better. Built from the ground up with thermoregulating Merino Wool, this micro crew blends a buttery upper with a reinforced heel, sole and toe box, fatigue-alleviating arch support and engineered forefoot mesh zones for the most durable, best fitting sock you can find. Product Details Men's micro crew socks average 8.5 in. from heel to cuff - expect them to rise about 6 in. above a running sneaker. A performance fit means no slipping, no bunching, no blisters. Here's to focusing on your run and not your feet. Arch support alleviates foot fatigue and bunching for long-running comfort with zero slippage. Flex windows mean less material where your foot needs to move the most so nothing interferes with your stride. Runners enjoy Merino Wool's ability to dry quickly and move excess heat and moisture away from feet. Our lowest profile, ultra-lightweight yarns create zero bulk, zero itch socks that feel like a second skin. The “still” in Still Made in Vermont, USA is personal. We knit all our socks at our VT-based Mills - we can't imagine it any other way. Unconditionally Guaranteed for Life - if these aren’t the longest lasting socks you’ve ever owned, return them for another pair.
