Ta for that. I like the idea of being a midfoot striker, which seems to be the point of running barefoot - it encourages you to do it naturally. Just watch a video of Anton Krupicka or someone trail running; he seems to just float along without any apparent effort.
I think those who criticise 'barefooting' are missing the point a bit when they criticise minimalist shoes, they are just a means of protecting the feet it seems to me, and easing the transition from running in 'platforms' to running with flat feet.
If only I could afford a pair!
