The Darn Tough Men’s Tactical Boot Midweight with Cushion Sock (Style T4021) in Black is a men’s tactical and duty sock with a mid-level cushion footbed that adds shock absorption underfoot through long patrol shifts and multi-day field exercises. The boot-sock height sits at mid-calf — clearing the top collar of tactical and combat boots so the boot leather doesn’t rub bare skin. True Seamless toe construction closes the front of the sock smoothly, so there’s no seam bump across back-to-back field days.
The knit — 62% Merino Wool, 36% Nylon, 2% Lycra Spandex — leans merino-heavy for moisture wicking and temperature regulation through hot deployments and cold patrols, and the nylon percentage carries the sock through repeated boot-friction wear. Targeted arch support gently hugs the midfoot so the sock stays in place through long ruck marches. Black is the standard duty colorway that pairs with law enforcement, EMS, and military uniforms.
Darn Tough knits every pair in Northfield, Vermont and backs them with an unconditional lifetime guarantee.
