I have never heard of shoes being compromised because of a wreck, except maybe the stiffness of the sole. Or maybe the bolt holes would be stripped but it doesn't sound like the screws/bolts that attach to your shoes were even part of the issue.

Did you install the cleats or the LBS? If you did maybe they can go over what might of caused it. If it was the LBS I would personally make sure another employee did it. Not that people can't have a bad day but I would keep wondering on my new cleats! Glad you're okay, that is the important part.
