I'm going to stop by tonight and pick up the black cleats
I think the black ones are the ones with 0 degrees float, so just make sure that's what you want. The gray ones are the ones with 4 degrees. Then the red have 9. (I could have gotten this mixed up, but anyway just make sure you are aware that there are 3 colors, not 2 out there).

Also, has anyone had any problems with their cleats coming unscrewed? I wear Shimano shoes and my Look cleats have tried to come off twice now (I've only been riding them for a few months). My LBS said it might be a slight mismatch between the Shimano shoes and the cleats, but that if I just buy some Lock-tite at the hardware store and put it on the screws that should fix it. Anyone else have that problem and any ideas about whether it's normal or not?
