You didn't fork over wads of cash for a bike built for both trails and the casual commute just to pedal around town in clipless shoes. Nobody wants to walk around the grocery store clicking and clacking down the aisle when you can push the Shimano PD-T8000 XT Pedals in both clipless and platform shoes. This is a pedal that you could clip in for long treks and then out for a technical line or more casual rides. On the clipless side, 2-bolt compatibility keeps you locked in for the long haul, and the platform side adds stability to both sides whether you're clipped in or not.
