I bought a pair of Shimano PD-A530 pedals. SPD on one side, platform on the other. I can jump on the bike in tennis shoes or put cycling specific shoes on for longer rides. I've gotten into the habit of unclipping a fair distance before I have to stop or before I get into a questionable situation, then simply let the pedal turn over and use the platform side until coming to a full stop. Works very smoothly for me with no major incidences.
