Have you tried 5 Ten shoes? These shoes have incredible grip on flat pedals and are the perfect marriage of shoe and flat pedal, if you want great grip but still the freedom of flats. DH"s use them a lot but i ride trail/all mountain and they are fantastic...a little pricey but worth it. www.fiveten.com look at the impact, baron, freeride and minnaar cheers,nic
