These all-new Merrell Men's Moab 3 Mid Waterproof Boots feature a new more supportive insole, a softer more cushioned midsole, and a best-in-class Vibram® TC5+ outsole. This new generation is the most environmentally friendly Moab ever, utilizing recycled materials in construction. These Moab 3s feature a waterproof membrane that seals out water and lets moisture escape. The Super Rebound Compound provides durable shock absorption in the heel to help reduce torque and allow for a smooth transition into the midfoot.
