I was debating between buying Saucony's Fastwitch4's or their lighter A3 shoes. The store I tried them on at didn't carry the A3, so I wouldn't be able to try them on before ordering, but they had the Fastwitch4's. The one thing that concerns me especially with racing flats is the width of my feet. I don't wear wides, but I'm almost right on the border. So sizing would have been tricky. When I tried them on and got on the treadmill at the store, the fit was awesome, they had a decent amount of support and were light.
