The METARACER is made for runners who want the most out of their fast-paced training and racing. GUIDESOLE technology features an improved toe-spring shape. This design is complemented by a carbon forefoot plate that gives structure to the curved sole. These two components are combined to reduce the movement of the ankle joint, helping runners save energy with each stride. The rolling motion of this shoe actually propels the foot forward, producing a totally unique running experience. Adding to it, the upper itself has drainage ports to release any water that might get into the shoe. The METARACER is designed to help you take your racing to the next level.
