As I have started running I have across more and more information disputing fancy running shoes. My husband, Bryan, read "Born to Run" by Christopher McDougall, at the recommendation of our friend Keith. The book has a lot to say on the Tarahumara or Rarámuri (meaning "foot runner" or "light-foot") tribe of Mexico, who, as a people, consider running a normal part of life. Many tribespeople run for over a hundred miles on simple sandals such as these:
These people have been known to chase deer on foot, capturing the deer when it drops to the ground OUT OF EXHAUSTION.
The book "Born to Run" argues that, like the title, evolution has slowly made humans better and better runners without the addition of footwear. We're born with the ability to run without orthotics.
