so no one posted yet about the flip flop style pedals, clips on one side, platforms on the other. many brands out there. I know the mallets are similar but it looks like the clips will interfere if your wearing normal sneakers.
when it comes to clipless I am sold on speedplay light actions. Assuming you will be wearing very stiff soled shoes, the sole becomes the platform.
if you have wide feet there are pedal spindle extender adapters that give you more room by moving your feet outward from the crankarms.
