I am needing to shim the right leg asthe knee moves outward as I pedal and feels as though it is reaching farther at the bottom of the stroke. I could of course have a more severe body alignment problems going. Straightening my cleats may force my feet into a better position for pedaling. Alot of float side to side is not always good.
I completely believe that too much float needn't be ideal, however I don't have a lot of experience with medium float. I tried giving SPDs a shot and they were an absolute no-go for me. I had a heck of a time getting them aligned properly, which made me very aware that either I completely destroy me knees, or I ditch the SPDs.
Hence I went with Speedplay's. Frog's for the mountain bike and X-2's for the road bike. I have no intention of being a poster boy for Speedplay, but I can say this: "Low float" vs "tons of float" has me knowing that "tons of float" is better for me. Pedals are bloody expensive so I haven't played around too much with the other pedals out there.
Having a couple wedges under my cleats (the Frog's use the SPD wedge) keep my feet from floating around so much on the pedals. That told me instantly that the wedge had significance. All of my shoes are also Specialized with BG and the angling that Specialized did in their shoes wasn't enough for my biomechanics.
