Darn Tough’s ATC Micro Crew Cushion Sock for men comes to just above the top of a standard hiking boot, and hits the perfect height for a low cut trail runner or hiking shoe. In addition to being an outstanding hiker’s sock, with mid-level cushioning underfoot, ribbed ankle support, and a performance fit with True Seamless™ undetectable seam fusion, 5% of ATC sales go to support the Appalachians Train Conservancy’s outdoor education programs and maintenance of America's first national scenic trail. Designed for rugged use this sock gives all weather performance thanks to a fast wicking action in warm weather and the insulating properties of wool in cool. The fine gauge knitting creates the most comfortable and durable sock you’ve ever encountered. Tested for days on the trail these socks don’t lose their shape, sag, or bunch, for a blister free experience day after day. And as with all Darn Tough socks these are Guaranteed for Life: no strings, no conditions. The perfect sock for the low cut hiker and your next trail adventure.
