So I overpronate really bad, and now have a pair of orthodics that have helped me. Running in normal shoes if fine, but I need to get a pair of spikes or flats for racing. I'm mostly racing track right now (1600 + 3200) I figured I'd be better off in a pair of racing flats and possibly seeing if I could get a pair that'd let me stick in my orthodics. Anyone have any expirience with this, your help's greatly appreciated.
