The Darn Tough Tactical No Show Cushion Sock (Style T4016) in Black is a unisex tactical and duty sock with a mid-level cushion footbed that adds shock absorption underfoot during long foot patrols, warm-weather deployments, and training PT. The no-show height sits below the ankle bone — invisible above low-cut duty shoes, boat shoes, and sneakers, so the sock disappears once the footwear goes on. True Seamless toe construction closes the front of the sock smoothly, so there’s no seam bump during back-to-back shifts.
The knit — 62% Merino Wool, 36% Nylon, 2% Lycra Spandex — leans merino-heavy for moisture wicking and temperature regulation during hot deployments and training runs, and the nylon percentage carries the sock through repeated shoe-friction wear. Targeted arch support hugs the midfoot so the sock stays in place through dynamic movement. Black is the standard tactical colorway for duty and PT use.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
