Runner's World + iPhone = Love

For all of you iPhone addicts...Runner's World launched its first app, sponsored by Nike. "Runner's World Shoe Shop" offers reviews from the RW Shoe Lab, shoe-buying advice and reviews divided into five categories: trail, motion control, stability, performance training and neutral-cushioned. Runners can watch various "how-to" videos, including "How To Find The Right Shoe For Over Or Under-Pronaters" and "How To Determine Your Arch Type" to decide on an ideal shoe. NearbyNow created the app, available for free at the App store.
