Go the distance in this shoe's long steady uphill heritage. Speed work and uptempo mileage are no match for you with the innovative KooshRide foam under your foot. The KooshRide Core is engineered to be long-lasting, so your stride is just as responsive at mile 300 as it is at mile 1. Combine that with the lightweight, breathable, irritation free fit of the SmoothFuse upper and nothing holds you back. A durable rubber outsole adds to this shoe's longevity.
