Familiarity: I've put it through the wringer
These shoes kill! The only knock I can come up with (and this is for the real nitpickers) is that the heel has a little dead spot, no matter how tight you size them. The great thing is you do not have to size them too tight for performance. See the full review here: http://verticali-culture.blogspot.com/2011/06/five-ten-quantum-review.html
I cannot recommend these shoes strongly enough. For an American-made produce (if that matters to you) these are as good as it gets!
