It comes down to this: Float is becoming an issue.

I am a lifelong (clipless) Crank Bros. user, and still like them, but am considering a switch to reduce the float in my cleats. I rode SPD in spin class a few times, and have never tried road systems. There are no knee problems, its just that the float makes my stroke sloppy. Trouble is, I need a shoe I can walk in. This is just a personal preference. I see Nashbar makes a road shoe that appears to be walkable, and there are probably others, but wondering if I might accomplish some tighter float with SPD.

I have also tried new CB cleats - improvement, but wondering if I will notice a difference with a road system (that I can walk in).

Insight? Informed opinions?
