Some selected links from my nightly surfing
I've read McDougall's "Born to Run" and loved it as a story and useful inspiration. It was not a book that gave the reader useful science or motivation to run barefoot. After all, even if our feet did evolve to run barefoot, I doubt they evolved to run unshod on pavement. If you go to this blog, the author is a bit jaded and contrarian, but he is pretty sound in almost all of his arguments. You won't catch me arguing with this guy!
