One of the most versatile socks you can buy, Darn Tough’s 11-inch tall boot midweight tactical sock with full cushion is tall enough to wear with a military combat boot, a tactical boot, or a dress boot, and versatile enough to keep you comfortable in moderate to cool climates whether you’re on a mission, or out for a hike with the family. Made from 62% merino wool 34% nylon 2% lycra spandex, the sock has dense terry loops that rebound quickly to keep the spring in your step. Terry loops under your foot, in the ankle, and in the lower leg to reduce pressure from boot laces. Darn Tough reinforces the heel and toe for durability without adding hot spot-causing seams. These socks won’t slip or bunch so you’ll be blister free, even if you wear these for days or weeks on end. They’re Berry Amendment compliant — knit with merino raised, sourced, and produced in the USA. They’re also US Air Force Safe to Fly certified, they meet flame resistant and “No Melt No Drip” requirements for next-to-skin use under approved flame-resistant combat and utility uniforms. Merino helps your feet temperature regulate, it’s breathable, and it reduces the chance of athlete’s foot and other bacterial and fungal foot infections. All Darn Tough socks are guaranteed durable. Wear a hole in one and Darn Tough will replace the pair free of charge, no questions asked. Whether you’re on-duty and need a uniform-compliant sock, or seeking socks for civilian life, these can’t be beat.
