Newton Running's top-of-the-line stability performance racer is the ultimate Natural Running shoe for people who pronate. Engineered for speed, distance and performance, this is the shoe Craig Alexander wore in consecutive Ironman World Championship wins in 2008 and 2009. With a level platform construction, medial posting to offset pronation and Action/Reaction Technology™, this lightweight, high mileage racer gets you to the finish line faster and with greater efficiency, quicker recovery and less overuse injuries (like achilles tendonitis and plantar fasciitis). Recommended for any distance just like its complimentary training partner, the Stability Performance Trainer.
