The Darn Tough Men’s Run No Show Tab Ultra-Lightweight Cushion Running Sock (Style 1039) in Black is a men’s no-show running sock built to stay hidden inside a low-cut running shoe — the cuff sits below the shoe collar with a protective heel tab that blocks friction against the Achilles. A thin cushion layer along the base of the foot adds gentle rebound without adding bulk inside the shoe. True Seamless toe construction closes the front of the sock smoothly so there’s no seam bump across long miles.
The knit — 48% Merino Wool, 48% Nylon, 4% Lycra Spandex — splits merino and nylon 50/50 so the merino handles moisture wicking and temperature regulation through hard training, and the nylon keeps the sock durable against repeated wear. The 4% spandex holds the cuff tight around the ankle so the sock doesn’t slip into the shoe. Black is the workhorse men’s training colorway that pairs with every kit.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
