  The soles are really thin but very tough. I've never had anything puncture through it including broken glass, although I wouldn't want to step on a nail sticking up! The wired article linked to a Tim Ferris (I think) blog post. That post had a video which will help you get a better idea of what the shoe is made from.

  YMMV - but I've had small sharp things hurt a little, like sharp bits of gravel, and never had anything pierce the sole. I've also ran over small amounts of broken glass by the side of the road before, no problem. The soles are really strong, but I wouldn't rule out a perfectly aligned spike or blade (scalpel tip or something?) going through -- but to be quite honest, something like that would probably damage a traditional running shoe; protection isn't a substitute for looking where you are going.
