The NEW 2009 Brooks Ariel running shoe is on sale now for $99.95! The Ariel has long served as a motion control superhero, coming to the rescue of runners with low or flat arches and excessive pronation. The Ariel® combines maximum support and long-lasting cushioning in a reliable motion-control platform. This synthetic and mesh shoe is both flexible and durable, with full-length MoGo midsole cushioning for extra support.
