The Darn Tough Style 1039 Men’s Run No Show Tab Ultra-Lightweight Cushion is a men’s running sock knit from merino wool in an ultra-thin profile with a small heel tab at the back and cushion placed under the foot. The heel tab stops the shoe collar from riding down and rubbing the Achilles, and the underfoot cushion adds a layer of impact absorption without pushing the sock into a visible height. True Seamless toe fusion removes the toe-box seam.
The Eclipse colorway a dark moody tone that pairs with dark boots. The ultra-lightweight merino build keeps the sock thin enough to fit inside a performance running shoe — no bunching in the toe box, no sliding under the heel — while the cushion adds comfort on long runs and recovery miles. Merino dries fast between runs and resists odor across a training block.
Darn Tough is family-owned and knits every pair at their mill in Northfield, Vermont. Lifetime guarantee covers running pairs just like boot pairs.
