newton running shoes...awesome!

First heard about this shoe from the triathlon community, and it comes highly recommended.  First video explains the technology behind the newton shoes.  The idea is to mimic a fore-foot, mid-foot strike as you would in barefeet.  Second video is NOT, in my opinion, proper running technique.  Sure, an all-out toe strike isn't recommended, but why go to the other extreme with an intentional heal strike?
