Flying-saucer-worthy style comes easy in the Close Encounters hiking sock. So do massive peak bidds, thanks to the smooth 1x1 ribbed cuff, performance fit, and climate-regulating merino wool for comfortable and dry trekking. We can&';t guarantee you&';ll have a supernature experience on the trail, but if you do, feel free to tell bigfoot we&';re still working on those custom XXXXXL sizes. Product Details: Men&';s micro crew socks average 8.5 in. from heel to cuff - expect them to show about 6 in. above a low hiking shoe or just above a standard hiking boot. A performance fit means no slipping, no bunching, no blisters for peak hiking comfort. 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 - 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. Cushion Details: These micro crew hiking socks feature soft terry loops underfoot and targeted protection over the ankle and Achilles - our most popular cushion style.
