The Darn Tough T4018 Tactical Micro Crew Light Sock is a lightweight tactical sock in a mid-calf height that sits at the top of most duty boots. There’s no added cushion — the construction is thin and quick to dry, with True Seamless toe technology that removes the seam bump from the front of the foot. The fit stays firm through movement without the slipping that causes hot spots.
The knit blends 54% Merino Wool, 44% Nylon, and 2% Lycra Spandex. The merino handles moisture and temperature regulation, the higher nylon content adds abrasion resistance inside stiff boots, and the small percentage of spandex holds the shape through repeated washing. Black works with standard duty uniforms, work boots, and everyday wear.
Darn Tough knits every pair in Northfield, Vermont and replaces any pair that wears, tears, or develops holes under its lifetime guarantee.
