Merrell markets the Moab as the #1 hiking boot in the world, and we sure do see the Moab 3 Waterproof Hiking Shoe almost everywhere we hike. This best seller features a mix of leather and synthetic mesh uppers for durability on the trail, Merrell's proprietary waterproofing for wet weather escapes, and Vibram rubber outsoles for more durable tread. Many of us wear the Moab as an all-purpose outdoor shoe that's not only appropriate for hiking but also walking the dog and working outside.
