If you're a serious thru-hiker that's miles away from the nearest town, blow outs, blisters and other sock B.S. can be disastrous. That's why we built this sock to outperform and over-deliver when you need them most.Specifications and Features: Women's boot socks average 10.5 in. from heel to cuff - expect them to show about 4 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.
