Why this gift works

The Darn Tough T4022 is a midweight tactical boot sock with full terry cushioning, knit from 66% merino wool, 32% nylon and 2% Lycra. It rises about 11 inches from heel to cuff, to the top of an 8-inch combat boot, and it is made in Vermont and Berry Amendment compliant. This listing is black in size Large.

Feet are everything in the military, and Darn Tough socks have a near-legendary reputation among troops and veterans for comfort and durability - backed by the company's unconditional lifetime guarantee.

Who is this gift for?

Great for

  • A service member heading into a cold-weather posting
  • A veteran who still hikes in boots

Think twice if

  • They work in hot weather
  • You do not know their size

The catch

Full cushion runs warm - Darn Tough itself suggests it for cooler climates or heavy loads - and a warranty claim means paying return shipping for a replacement credit.

Skip for someone deployed or living in hot weather, where a lighter cushion suits better.

What to look for in boot socks

  • Cushion level. Full cushion suits cold and heavy loads; lighter cushion suits heat.
  • Height. The sock should clear the top of the boot.
  • Merino wool. Merino resists odor and stays warm when damp.
