I run RXE's on my bike. There is some float (not sure how many *, I'm sure it says on the Time website), but its not awkward. There is a centering tension that brings your feet back to center, and prevents your feet from excessively rotating around the pedal.

I like the pedals. They are cheap, have a very definite clip in and release, and are extremely easy and natural to clip in and out of. I don't even think about it anymore.

I would recommend them.
