After reading this thread, I asked my lbs about the A520s. They seem like they are just what I was looking for. I wanted a lighter pedal that I could use not clipped in also, but the old shimanos were heavy and cumbersome. He said he had been thinking of carrying them and I could be the guinea pig. They're in, but it snowed a bunch here yesterday so I couldn't go get them.

Coyote - I know it's been awhile, but I want to hear your reviews and I will post mine as well. I have had the hotfoot problem, and took care of a lot of it with metatarsal buttons. Hopefully these will be the answer to that and not wanting to clip in all the time. At just a little over 300g, they aren't too cumbersome either.
