The AR 670-1 compliant GORUCK MACV-2 8" Boots feature an all-new outsole for unprecedented traction and even more support. It is suitable for the needs of Special Forces soldiers who spend a career on their feet, all over the world, with heavy rucks on their backs. It is also suitable for all adventurers who are looking to support their feet on long trips and journeys and in their daily active lives. Each section of the triple compound rubber outsole is designed to perform a specific function. The forefoot rubber is formulated for increased grip with deep tread specifically shaped to grab the ground while shedding mud and debris. It wraps around the toes for additional protection against rocky terrain or when doing push-ups. The midfoot is formulated from a rock climbing compound and hardened for exceptional abrasion resistance, ideal for fast roping. The updated midsole design wraps around the entire upper, providing more stability and maximum support. At 17oz (34 oz/pair for 6"), MACV-2 is still lighter than any footwear of its kind, even with the new aggressive outsole. No break-in time, ready to go right out of the box. A wide toe box allows room for swollen feet. Built with the ideal heel-to-toe drop for rucking, a 13mm offset reduces the strain on your achilles (and your ankle, knees, and hips). Shielding drain holes keeps sand and debris out and repels moisture with every step. The upper features full-grain Challenge Leather™ (Black) or suede (Coyote), paired with 1000D CORDURA® and 2" nylon webbing for added ankle support. A dual-layered compression foam system supports your entire foot from heel to toe - including contoured arch support for all 3 of your arches.
