    How high is "quite high"? Though the canonical advice is, of course, "replace it", I'd not be too worried about a helmet that dropped from 6 feet or so, so long as a reasonably close inspection reveals nothing.

  • I wonder if physical analysis of the energies involved can approximately be carried out. After all, a helmet has far less mass than a helmet + rider.

  • @Daniel it is indeed around 6 feet. A quick inspection revealed very small irregularities, small cracks in the foam, at the spot which I suspect hit the floor. For now I'm inclined to think that it is damaged, but it is true that it still looks new from the outside...

  • Motorcycle helmets have more mass so they would hit the floor with more force (but they are designed to absorb more force as well). A fall will possibly crack the shell on them as well. The shell is used to prevent punctures (source: beginner riding course) so a crack could compromise that protection. I would just inspect it, try pushing on the shell to see how far down it goes, and then ask "how do I feel about using it".
