Moab stands for the "Mother of All Boots," and the Moab 3 Mid Waterproof Hiking Boot has indeed been Merrell's best seller for many years. This budget-friendly hiking boot features a wide fit for those of us who need extra room, Merrell's proprietary waterproofing for wet weather, and Vibram rubber outsoles for durable tread-a premium feature for this price point. Thanks to Merrell's comfort, the Mother Of All Boots is also a popular, all-purpose pick for walking the dog, working on our feet, fishing, mowing, and landscaping.
