Full of tradition and Hanwag quality, the Nazcat shoes are made for tough going. A wide rock guard and durable leather material make for longevity. In the ABCD stiffness classification system the Nazcat scores a solid BC, making it suitable for carrying a heavy backpack in rough terrain. Their mid soles are stiff enough and their ankle support rigid enough to help your feet through days on end. - Regular Hanwag last - Gore-Tex membrane keeps water out - Tough metallic lace hooks - Padded tongue with a supple textile lower - Vibram Fuora outer sole The surface is treated with wax and spray care products. Of these, the wax has a longer life. We suggest you buy at least the spray with the boots. It's easy to see when the treatment loses its power: just step into a puddle. If the water beads beautifully on the material, things are fine. If, however, the leather gets wet quickly, it's time for a spray.
