I recently got a set of WPD-823 pedals to use with my second bike, I tried to clip into them today with my SPD cleats, and could not. I swapped pedals from my other bike, and used those for the ride. Now I need to figure out how to get my cleats to fit the 823s, as they are supposed to. The cleat is the Shimano SM-SH55 mounted on some Diadora MTB Shoes. The pedal that works with this cleat/shoe combo is the Shimano PD-M525.
What do I need to do to get a cleat that works with both pedals?
