The Light Hiker MICRO CREW Light Cushion hike Socks by Darn Tough brings Vermont’s outdoor technical savvy to a breathable hiking sock made lightweight and durable. Merino blend fabric breathes and wicks moisture, and mesh panels help keep things cool. The cushion extends to the back and up the Achilles. Durability comes through the fine gauge knit and a performance fit keeps the socks from slipping, bunching or blistering.
