Cleats slipping

[VeloVT]

I have no experience with Looks -- but is it possible that you are a)using the wrong screws for your cleat/shoe (too short?); b) have stripped the screws (it can be surprisingly easy to strip by overtightening); or c) need some kind of adapter to use the cleats with your shoes?

I had that happen with screws that were too small.
