I'd take off the Vibram Five Fingers, unless you caution your running geek to take it easy in them.<p>In a marathon I did on Sunday there was a lady wearing VFFs who already had two stress fractures, but was still determined to run in them. We questioned that decision....<p>I think some people might be reading "Born to Run" and jumping full on into barefoot running and VFFs without taking the time to get their feet used to the minimalist style! That said, they do work for a lot of people.
