25 degrees of float sure sounds like an awful lot of slop for a road bike. Also, doesn't that mean that you'll *really* have to turn your leg to get out of the things? That's not so good when someone brakes in front of you or a car pulls out quickly from a side street.
If you're thinking that your knee problems are being caused by having your leg fixed in an uncomfortable position, then maybe it'd be worthwhile to experiment with angling your cleats slightly inward or outward to match the natural standing angle of your feet (you know, to match a pigeon-toed or bow-legged condition). The pedals should be comfortable if the cleats are aligned correctly, and a few (4-6) degrees of float from the natural position should be plenty to allow one to wiggle/relax the legs from time to time. Just a thought.
I gave a lot of thought to your comment. And also all the other comments on this question. I want to thank everyone who gave their experience here.
I got a sheet of paper and a protractor and drew 25 degree and 15 degree angles on it, and taped it to the floor. I tried putting my foot at different angles to be able to visualize what they're talking about.
I also checked out the cleats pretty carefully to see how much I can adjust them so that they're on a slightly different angle on the shoe.
For now I'm going to try the Speedplay Zero pedals. They can be adjusted from zero to fifteen degrees of float. I'm convinced I can adjust the cleat on the right shoe so that I can be slightly pigeon-toed on that side, because that's where my foot wants to go.
Thanks to everybody!
