Just got a pair of SIDI Lightning shoes to go with speedplay pedals/cleats. The Speedplay cleat mounting system uses 3 screws, the 2 on the outside left and right and the one in the center front. The fit seems good except there is the center mounting plate built into the SIDI shoe that goes unused and as a result it rattles around inside the shoe while pedaling. I would expect there is a way to take this unused piece of hardware out of the shoe since it is nothing but noisy dead-weight, but the second insole of the shoe is unremovable and glued in and there seems to be no practical way of getting to the plate from the bottom? Any ideas? I have researched the SIDI and Speedplay websites with no answers, the booklets that came with both have no explanation of this plate, and Google has led me here! Please help! Thanks.
