The sock that made a name for itself from the Pacific Crest Trail to the AT. "Must pack" durability meets undeniable comfort in a Full Cushion sock that absorbs the rigors of the trail.Specifications and Features: Men's boot socks average 11 in. from heel to cuff - expect them to show about 5 in. above a standard hiking boot. A performance fit means no slipping, no bunching, no blisters for peak hiking comfort. We close every toe seam using our True Seamless Toe technology for an ultra smooth, undetectable feel. 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. Our all-season weight, midweight socks thermoregulate to wrap feet in steady comfort when temperatures change. The "still" in Still Made in Vermont, USA is personal. We knit all our socks at our VT-based Mills Unconditionally Guaranteed for Life - if these aren't the longest lasting socks you've ever owned, return them for another pair.
