Barefoot running or minimalist running (Vibram Five Fingers etc) seems to be all the rage lately. I am not sure if this is the cure for all but as Joe says the aim should be for us all to run in the least supportive shoe that we can. Not necessarily that we all run with no support at all.
Barefoot drills are really fun and I am incorporating them into my weekly training. Just avoid the dubbletjies!
Would love to hear your ideas and who of you run barefoot, why, when etc.
