BlackHawk's Warrior Wear Light Assault Boot dries quickly with Dri-Lex inner lining and an upper of breathable nylon mesh and quick-drying, synthetic microfiber. It has a Vibram "Trail Run" outsole, a waterproof molded insole board with built-in shank, non-woven reinforcement inside the heel, and a custom-molded OrthoLite footbed designed not to lose effectiveness over time.
