The Men's Run No Show Tab Ultra-Lightweight with Cushion (Style 1039) is the toughest sock you'll never see. A streamlined no-show profile with a back tab keeps the cuff from slipping into your shoe, while ultra-lightweight Merino wool wicks moisture, regulates temperature, and resists odor mile after mile. True Seamless construction lays smooth across the toe to prevent blisters, and targeted cushioning under the foot adds rebound without bulk. Knit in Vermont, USA and backed by Darn Tough's Unconditional Lifetime Guarantee. 48% Nylon / 48% Merino Wool / 4% Lycra Spandex.
