The Mizuno Women's Wave Rider 18 Running Shoe helps you flow down sidewalks and streets. Equipped with a U4ic midsole and Mizuno's innovative Wave plate at the heel, the Wave Rider 18 boasts optimal forefoot flexibility to ensure a smooth stride. Its upper features soft pliable mesh that wraps snugly around the midfoot and heel for a secure fit that disappears while you run. An upgraded sockliner gives the Wave Rider 18 more rebound and resiliency at each foot strike, and Mizuno refined the toe spring for a more effortless toe off. Durable X10 rubber covers the hard wearing areas of the sole, while carbon enhances shock attenuation and lessens the weight of this already lightweight shoe.
