A cool combination of materials makes these men's boots from N91 real statement pieces. The combination of water-repellent CORDURA®, a resistant nylon fiber, in the forefoot area and on the shaft, and the water-repellent leather creates a super reliable shoe for autumn and winter. But that's not all: The rugged rubber sole with its strong tread also impresses on wet surfaces, while also completing the mountaineer look of the boots.
