Set lofty goals, then follow through with your plan. These running shoes support progressively longer runs. The rocker geometry creates a smooth ride and generates forward momentum. A soft engineered-mesh upper with internal support reduces irritation for plush comfort every step of the way. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic — reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
