No changes to fit, no changes to training, just the pedals slowing getting worse until they got out of hand. Strangely enough, when my iClic cleats did something similar, no pain at all. Just felt really unstable attacking or sprinting, so now I'm on RXS's and hoping the brass cam holds up better.

Speedplays are great if you have money to replace pedals and cleats when they're toast. Shimano is great if you don't want free float and don't want to think about your pedals ever again after putting them on the bike.
