The Darn Tough Style T4022 Tactical Boot Full Cushion Sock is a mid-calf merino wool sock knit with high-density cushion running the length of the foot. The cushion absorbs impact across long patrols, training ranges, and extended foot time on hard ground, and the fine-gauge knit keeps the sock compact inside a tactical boot. True Seamless toe fusion removes the toe seam.
Mid-calf boot height clears the top of a standard tactical boot, and the Black colorway the universal pick — disappears under any boot or pant. The 66% merino wool / 32% nylon / 2% Lycra blend is the workhorse tactical build — warm without overheating, fast-drying after water crossings, and resistant to odor across multi-day use.
Darn Tough knits every pair at their family mill in Northfield, Vermont. Every pair — including the full tactical line — carries an unconditional lifetime guarantee.
