Youth over the calf socks average 13 in. from heel to cuff - expect them to cover the leg to just below the knee. A performance fit means no slipping, no bunching, no boundaries. Here's to feeling connected and comfortable in your boots run after run. Flex windows remove material in strategic areas to create a sock that's less bulky and really moves with you. We close every toe on our socks using our True Seamless™ technology for an ultra smooth feel that's kid-approved. Merino Wool has a natural ability to move heat and moisture, keeping skier's and rider's feet warm and dry. Our silky, ultra-lightweight socks are smooth, breathable, and feel like a second skin between your feet and boots. 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. These no cushion socks are ultralight and smooth - these are the best thin socks for skiing or snowboarding. Darn Tough Youth RFL Over-the-Calf Ultra Lightweight Ski & Snowboard Sock
