The Zamberlan Vioz Plus GT has a full-grain leather upper with minimal stitching; Gore-Tex waterproof lining; full rubber rand; incredibly stiff, supportive upper; stiff outsole; aggressive Vibram sole unit; incredibly durable boot for the toughest terrain. But it weighs 2030g (pair, size 11); may offer more performance than walkers will need; pricy if you don’t need this performance.
