The Darn Tough Light Hiker Micro Crew Light Cushion Sock protects your foot from the harsh environment of your burly boot while keeping it cool and comfortable. A blend of merino wool and synthetic materials pull perspiration away from you, and the knit naturally resists the buildup of odors--which you'll appreciate on multi-day trips. The Micro Crew height hits just high enough on your ankle to protect your skin from the tongue of your boot, and the True Seamless design sits smoothly against your toes to minimize chafing.
