Moreover, our society evolved towards a different direction. The one in which we use shoes. Going back in time to a shoeless life will probably sound cool and alternative. That doesn't mean the way to go. Those who are practicing barefoot running without getting any injury are, on average, not very long distance runners. The very few who can run far represent such a negligible part of the running community that they cannot and should not be taken as successful examples. Even in the scientific community there are numerous doubts and lack of evidence about the effectiveness of barefoot running. Keep barefoot running as an exercise. Not a philosophy!
This, of course, is just personal advice.
