The ProMorph is Merrell's all-terrain hybrid shoe, built to handle roads, trails and everything in between with one pair. A FloatPro+ supercritical foam midsole delivers lightweight, enduring cushioning, while FLEXconnect dual-directional flex grooves keep you connected to the ground on uneven surfaces. A Vibram XS Trek Evo outsole balances grip and durability across wet or dry, road or trail conditions, and a breathable synthetic-and-mesh upper uses recycled materials throughout. Best for runners who don't want to choose between a road shoe and a trail shoe.
