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?
