Ok, so I've determined the type of pedals I want for my bike - Crank Brothers or frogs. Now how do I know what shoes will work with the pedals? I realize some shoes are look, spd, spd-2, etc, but I haven't seen a shoe yet that says Crank Brothers or frog compatible.

I know there's something I'm not getting, I just haven't been able to figure out what, in spite of copious search function usage.

Someone got a quick answer?
