I am relatively new to cycling and ordered the vector 3 pedal. Based on look they seemed to be the same as my Shimano pedals. I thought there was only two types of pedals (2 hole and 2 hole) with just different manufacturers. I am to understand that this is incorrect, and the Garmin Vector 3 pedals will not work with my shimano shoes/cleats? IF this is true, does Garmin make a Vector 3 for Shimano shoes/cleats? Are all three hole shoes the same and just the cleats different so I can keep my shoes? Or would I need to switch those out too?
