Does anyone know what flats the Saucony athletes (Stinson, Droddy, Thweatt, etc.) were wearing at the Chicago Marathon this past weekend? Saucony shoes seem to fit my feet well, and I've been wearing the Type A9 flat for racing. While they're great up to the 10k, I'm looking for something more substantial for the half marathon and beyond. Their flats looked more cushioned that the Type A9, but definitely weren't something like the Kinvara.
