I can see the sense in barefoot running for therapeutic reasons - if it works of course. I slam down pretty heavily on my heels myself. I'd imagine there are some problems it would exacerbate on the other hand. I've got a cracking bunion on my left foot, & I use orthotic padding in my running shoes to reduce the amount the joint bends while I'm running. Running barefoot just sounds such a bad idea given this, but I'd be interested if I thought it might be of benefit. In the right fields of course...
