YouTube - Christopher McDougall; Are we born to run (TED)

Your thoughts? He talks about running shoes around the 12 minute mark, and says that most running related injuries are caused by the shoes. Then he goes on to talk about how running barefoot is so much better for you, which I find hard to believe.

For me it's kind of painful to run in bare feet, it might be because I have a very high instep, I don't know. I know the natural instinct when running barefoot is to land on your toes. When we have shoes on we tend to pound away at our heels, so maybe that's where the injuries come from?
