I just thought I'd chime in: I just got a pair of Giro Republics and the A530 pedals, and it seems like the pads on the bottoms of the shoes don't allow for a tight fit (or a fit at all) for the cleats to connect to the pedals. I'm actually pretty frustrated and hope it is user error, because now both the shoes and pedals are all marked up and un-returnable because I've been trying to make them work...
