The new Ravenna 11 is designed for fast training sessions and racing. An updated single-mesh upper feels lighter-weight than previous models. BioMoGo DNA cushioning is a firm and responsive material designed to increase energy return when running faster and a new rebound rubber on the bottom further enhances energy return. GuideRails provide holistic support and help improve stability for feet and legs. Runners who don’t want to compromise on support and want an advantage for faster runs should try the Ravenna 11.
