The Darn Tough Style T4033 Tactical Boot Extra Cushion Sock is a fine-gauge merino wool sock knit with the highest wool content in the Darn Tough tactical line — 80% merino. Higher wool percentage means warmer insulation, stronger odor resistance, and softer hand, all traits that matter for tactical use where the sock stays on through long shifts and sweat resets. Extra cushion density runs under the foot for impact protection on hard floors and uneven ground.
Mid-calf boot height fits under standard tactical and combat boots, and the 80% Merino Wool / 19% Nylon / 1% Lycra Spandex blend keeps the sock stretchy and shape-stable through a long day. True Seamless toe construction eliminates the seam that rubs on extended wear. Unisex sizing — the same sock works for duty wear across different foot shapes.
Every pair is knit at the Darn Tough family mill in Northfield, Vermont, and carries the same unconditional lifetime guarantee as the rest of the line.
