Kids' micro crew socks average 6 in. from heel to cuff - expect them to show about 4 in. above a low hiking shoe or just above a youth hiking boot. A performance fit means no slipping, no bunching, no blisters for peak hiking comfort. We close every toe on our socks using our True Seamless™ technology for an ultra smooth feel that's kid-approved. Reinforced footbed and Achilles cushion improves the comfort of our socks and helps them last longer. Merino Wool is at home on the trail, naturally moving moisture to keep feet fresh and dry in all weather. Lightweight socks breathe naturally and deliver flexible, all-day comfort for summer hiking. 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. Darn Tough Van Hike Lightweight Hiking Sock Youth
