Agreed! The thing with barefoot running is that it's a new (although also very old!) discipline.
We know people have run barefoot for thousands of years, so we can infer it's how we were originally designed to run. But modern people and the modern environment are different to our ancestors, so we need to re-learn the ancient technique and see how it fits with 21st century life.
A lot of people are making bold statements about barefoot running (some of them conflicting!), but until we learn more about it and get more research we should probably stay a little bit sceptical.
Jason Robillard's site is very good for that. He seems to have a balanced approach, unlike some other barefoot gurus who seem to treat barefoot running like a new religion and the panacea for all ills!
