Chris McDougall

Found this great PopSci interview with the author of Born to Run. Includes a nice video of his putting his feet where his mouth is. Best quote:

I have the idea that running shoes are based on a kind of cult idea -- that our feet are flawed and we need shoes to correct those flaws. The shoe companies are in the business of selling shoes. But there's no evidence from running shoe manufacturers that they're right. There's no scientific data that running shoes reduce injury.

Also, here is McDougall appearing on Jon Stewart.
