I switched to Speedplay pedals a couple years ago due a knee problem and I've been very happy. I had severe pain in my right knee due to a standard pedal holding my foot too straight. I switched to speedplay pedals with a 1/2" longer right and 1/8" longer left pedal spindle so my feet could point out more to their natual position and my knees have been very happy! I got fit tested after the pedal change and at the beginning of the fit test the fitter said having different length spindles was bad idea but after all the video analysis they agreed that it was just about perfect. Unfortunately you can't get the titanium spindles in the longer sizes.

I was worried the Speedplay shoe cleats would raise my shoes higher than the Shimano cleats I was using due to the Speedplay adaptor plate but they are actually a little shorter even with the adaptor.
