Pound the ground and put in the miles. It&';s never easy, but at least it&';s comfortable with the ultra-lightweight Stride running sock. Extra durability was knit into the heel, footbed and at the first and fifth metatarsal (outside toes). This micro crew sock features smooth, anti-chafe Merino Wool, with cooling mesh and a low-profile, next-to-skin fit that will match any hundo you throw its way. Height: Micro Crew Weight: Ultra-Lightweight Pair with: Trail runners, running shoes, athletic sneakers Product details Women&';s micro crew socks average 7.5 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. No Cushion Our no cushion Running socks offer the ultimate next-to-skin fit and ultralight comfort. Blister-Free Running Beyond the moisture-wicking our running socks swear to, their fit is equally key. With a truly seamless wrap around your foot, they fit well and work well with any running shoe - trail or road. Depending on your style or desired features, we have heights ranging from no-shows and quarters to micro crews and over-the-calf run socks. All are knit with our ultra-lightweight yarn, while some styles have cushion for added protection and comfort. The best fit you&';ve ever worn, accompanied with Merino&';s performance, leads to incredible comfort that will leave you blister-free.
