Only a real runner can help a runner find the right running shoe. Duncan Cragg, a Dallasite by way of South Africa, is not only a runner extraordinaire, he's an expert on kinesiology and stride and all of that high-tech study-of-movement blah-blah. He'll tell you which styles and brands of shoes you'd need depending on what distances and speeds you're running, then have you put them on and take a jog around the in-store track. He'll analyze your gait and pronation and produce the perfect shoe to further your fleet-footed dreams. Ready, set, go!
