Is it possible to keep a limited-edition shoe limited? Not this one. Previously only available surrounding major running events, this shoe’s popularity rose as fast as it runs, so we decided to bring it in-line, making it available at all times. The Racer is built for performance with our powerfully plush Altra EGO™ midsole thats a touch firmer than the Escalante 2.5 for more return and a more responsive feel along with a static mesh upper thats highly breathable. Race on, Escalante.
