I was reading up that the "Speedplay zero" has a unique float and a wide range, but when reading up on the page dedicated to the "Speedplay zero" it mentions thatit is for
Rider who prefers a fixed (no float) or limited-float pedal system in the section labeled "why get this pedal." It had also mentioned on the top of the page that it has a varying float, and that it has multiple adjustments to adjust the cleats perfectly for yourself.
I am curious if anyone has any experience with these as I am looking for a pedal that has a good amount of float so that I do not experience knee injury. I heard the Speedplays and "Keywin" companies were good for that.
