The Saucony Ride ISO 2 is designed to deliver a balanced feeling between cushioning and responsiveness. PWRFOAM, a protective and soft foam, is positioned underneath a high-energy-returning material called EVERUN. An ideal combination for runners who want to be comfortable over longer distances at slower paces and also want to push the pace in tempo runs and intervals. An updated upper with woven heel fits more securely than previous models. Arch support is delivered by a sculpted insole that conforms to the shape of your foot.
