The Darn Tough Men’s Run No Show Tab Merino Ultra-Lightweight Cushion Sock (Style 1039) in Black is a men’s no-show running sock with ultra-lightweight cushion density under the foot — the thinnest platform in the Darn Tough line for a barely-there feel inside running shoes. The integrated heel tab sits just above the shoe collar to prevent rubbing, and True Seamless toe construction closes the front of the sock smoothly so there’s no seam bump at the toes during high-mileage runs.
The merino-forward blend handles moisture wicking and temperature regulation across cool mornings and warm afternoons, while the nylon-and-Lycra percentages keep the sock dialed tight to the foot without slipping. The no-show height disappears inside running shoes and low-cut athletic shoes. Black is the standard neutral colorway that pairs with every shoe in the running rotation.
Darn Tough knits every pair in Northfield, Vermont and backs them with an unconditional lifetime guarantee.
