I wrote a little bit about barefooting here. Not because I wanted to convince anyone that running barefoot is better, but because I think it helps to share our experiences. We can all find research -- in this day and age -- to prove and disprove almost anything, and the water gets muddier and muddier. Talking to people with similar problems, and hearing what has worked for them helps to clear that water just a little; it's more relevant.
Whilst there is no panacea for running injuries, there does seem to be a significant number of people who have tried running without shoes and found it helps (me included). I'm no super-efficient natural, 'neutral' runner; indeed, for years, I was of the firm view that orthotics were the only way forward for me. But, 6 weeks in, running a few miles a week barefoot is doing me much more good than harm. Early days, yes, but it's fun, encouraging, and providing a new dimension to my running that I'd never have dreamt existed.
