Take some weight off your feet during your next hike with the Montrail Men's Fluid Fusion OutDry Hiking Shoes. Borrowing design principles from trail runners, the Fluid Fusion hiking shoe sports a breathable mesh upper, which is supported by a seamless synthetic skeletal frame. Backed by a waterproof, breathable membrane, the shoes are completely waterproof. Where the shoes really stand apart from trail runners, though, is with their burly Gryptonite rubber soles. With multi directional lugs, an aggressive tread pattern, and abrasion resistant rubber, these shoes will grab hold in the most demanding terrain for a sure footed feel.
