The Darn Tough Men’s Run 1/4 Ultra-Lightweight Cushion Running Sock (Style 1040) in Blue is a men’s running sock with a thin cushion layer along the footbed for gentle rebound through long training miles. The quarter-height shaft sits just above the ankle — high enough to clear the collar of a low-cut running shoe or hiker, low enough to stay out of the way on fast-paced miles. True Seamless toe construction closes the front of the sock smoothly so there’s no seam rubbing across back-to-back training days.
The knit — 50% Merino Wool, 46% Nylon, 4% Lycra Spandex — uses an even merino-nylon balance where the merino handles moisture wicking and temperature regulation across morning runs and hot afternoons, and the nylon keeps the sock durable against repeated shoe-friction wear. The 4% spandex holds the cuff tight around the ankle so the sock stays in place. Blue is the cool-toned men’s training colorway.
Darn Tough knits every pair in Northfield, Vermont and backs them with an unconditional lifetime guarantee — any pair that wears, tears, or develops holes gets replaced for life.
