Danner Men's Stumptown Mountain Pass GTX Boot combines classic lines with lightweight, modern technology. Full grain leather upper is durable and waterproof and also covered with a waterproof and breathable GORE-TEX membrane which keeps your feet dry and at the same time allows moisture to escape during your hike. Removable polyurethane footbed provides some cushioning when moving and a Bi-fit midsole provides stability especially when carrying a heavy load. To keep you from slipping Danner added Vibram Kletterlift Thin rubber outsoles which provide excellent grip without adding weight.
