It is possible that the cleats are mounted upside down, so check that. I recently bought a pair of shoes for spin class and since I was pressed for time, the guy at Performance helped me move the cleats over from an older pair of shoes. Couldn't get the right foot locked in at all, though it seemed like it was aligned as well as possible. Turned out the one he installed was upside down. The side of the cleat with all the little grippy nubs faces the sole of the shoe. The rounded point faces forward, square end to the rear.
