Rugged all-terrain and built with nothing but the best materials. Developed side by side with the United States Marine Corps, the M.E.B. (Marine Expeditionary Boot) earned its name among elite warfighters as being the only proven USMC rugged all terrain boot available. Precisely crafted with a highly durable nubuc leather, a tear resistant 1000 Denier nylon, and an advanced Vibram® 360 Dri Ice outsole, the M.E.B. embodies Danner's commitment to crafting higher standards.
