Hi gadabout55,

Just to help summarize (since I still use "old-style" Look delta pedals). New shoes are still compatible with the old delta cleats. Depending on the age of your Look pedals, you may need to buy black, non-floating cleats. The red (floating) cleats are NOT compatible with older Look pedals. The new Keo cleats are NOT compatible with ANY of the delta cleat pedals. The original Shimano pedals (not sure about the model numbers) are compatible with black Look cleats only. Shimano SPD pedals are not compatible with any Look cleats.

Since this question comes up periodically on many of the forums, I've been searching the internet for a list of Look pedal models and cleat compatibility and I have not found such a list yet. If anyone finds one let us know.

Hope this helps.
