The METARACER shoe is made for runners who want the most out of their fast-paced training and racing. The upper is designed to capture as much airflow as possible, which helps keep feet cool. This cooling provided by the shoe means your body does not have to work as hard to keep you cool. The upper also has drainage ports to release any water that might get into the shoe. GUIDESOLE™ technology features an improved toe-spring shape. These two components are combined to reduce the movement of the ankle joint, helping runners save energy with each stride. Combined with a carbon fiber plate in the midsole, this shoe generates a rolling motion that actually propels the foot forward, producing a totally unique running experience. The METARACER shoe with GUIDESOLE technology is designed to help you take your racing to the next level.
