BMX pedals. Pros use clip in pedals for a number of reasons. They often ride for three or four hours without stopping, and don't need to take their feet off the pedals until the end of the stage or the end of the race.
Urban riders with bike shoes and clip in pedals look silly. Every hundred yards, they need to put their foot down at a stop sign or red light (or they can run the red light, to avoid putting their foot down).
Then, they get to Starbucks, and look as if they are iceskating, as they slip and slide across to the cash register.
Not racing? Ride in the city? Just get a good pair of MKS BMX style pedals (for places such as Rivendell.com...the owner of Rivendell uses BMX pedals on a $3,000 bike). As a bonus, you can wear any shoes you want. Dress shoes. My favorite for riding, skate board shoes. Or even sandals. Get where you are going and WALK into the store instead of sliding.
Of course, if you ride in a group, and everyone in your group using racing pedals, you will get called names. Last time I posted on this topic, the most common name was "moron".
But, you will be the "moron" who is standing up straight at the red light, while your buddy picks himself up off the ground.
