The Merrell Nova 3 shoes are designed for trails with moderate debris and obstacles, and occasional speed, direction, and vertical changes. They feature a breathable mesh lining, a recycled mesh footbed cover, and an EVA foam footbed. The NXT lined footbed cover helps keep your stride odorless, and the rock plate provides extra protection from bumps, bangs, and bruises. Merrell Air Cushion shock absorption and stability provides a comfortable and responsive ride.
