The Darn Tough T4033 Tactical Boot Extra Cushion Sock is the heaviest, most cushioned sock Darn Tough makes. High-density padding runs through the entire sock — not just underfoot — for maximum impact absorption and warmth in tactical and hunting boots. True Seamless toe construction removes the seam that causes blisters on long missions.
It’s built for military, law enforcement, and hunting use — long patrols, cold-weather operations, hunting boots, and work boots on job sites in winter. The 80% merino wool content is the reason: it wicks sweat and stays warm when wet, resists odor across multi-day wear, and regulates temperature in both cold and warm conditions. Nylon and Lycra hold the sock on the leg under heavy boot use.
Darn Tough knits every pair at their family-owned mill in Northfield, Vermont with yarns sourced from America and around the globe. Every Darn Tough sock carries an unconditional lifetime guarantee.
