The Darn Tough Men’s Run No Show Tab Ultra-Lightweight Cushion Running Sock (Style 1039) in Sandstone 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 Achilles rubbing. A thin cushion layer along the footbed provides gentle rebound without adding bulk. True Seamless toe construction closes the front of the sock smoothly so there’s no seam bump during fast miles.
The knit — 48% Merino Wool, 48% Nylon, 4% Lycra Spandex — balances merino and nylon evenly so the merino handles moisture wicking and temperature regulation through hard workouts, and the nylon keeps the sock durable against repeated shoe-friction wear. The 4% spandex keeps the cuff tight so the sock stays put. Sandstone is a warm neutral colorway that pairs with tan and neutral training kits.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
