The Darn Tough Men’s Run 1/4 Ultra-Lightweight Cushion Running Sock (Style 1040) in Gray is a men’s running sock with a thin cushion layer of soft terry loops along the footbed — gentle rebound underfoot without bulk inside the shoe. The quarter-height shaft sits about three inches above running shoes, clearing the shoe collar without riding up the shin. True Seamless toe construction closes the front of the sock smoothly so there’s no seam rubbing across long training miles.
The merino wool, nylon, and Lycra spandex blend lets merino handle moisture wicking and temperature regulation through morning runs and hot afternoon miles, while the nylon percentage keeps the sock durable against repeated shoe-friction wear. Targeted arch support gently hugs the midfoot so the sock stays in place during long runs. Gray is the neutral men’s training colorway.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
