Science of barefoot running

so barefoot for me is, in part, about finding a simple way of doing things.
However, the health / injury avoiding benefits form a big part too. running barefoot is meant to reduce impact injuries commonly associated with shod running due to a front-foot strike that uses the foot's structure to manage your bodies weight with each step better than the heel strike encourage by all the padding in modern shoes.
obviously these claims meet with scepticism from some quarters, but they are also being backed up by some serious research.
