I ride flats and love them. I have some foot problems and clipless is not an option any more. My touring shoes-Pearl Izumi's cause a pain on the out side edge when I do over 10m. They are just not stiff enough. So,anyone have a recommendation? Most shoes are for clipless or sticky for flats-with a flexy sole. My pedals are 100mm by 100mm so wider pedals is not it either.
