Darn Tough gave the Merino Wool Micro Crew Cushion Hiking Sock a dash of spandex and nylon so your trail-tromping paws stay extra comfy while you tick off the miles. The Micro Crew blows away your heavy, itchy wool socks with its built-in elastic arch support and high-density padding in the heel and toes. Darn Tough built these midweight beauties with merino wool that's naturally resistant to stinky odors and manages moisture to keep your feet blister-free.
