a little info for you guys.
The idea for that shoe came out a long time ago. Sometime before 2000. A kid from MIT came up with it. His name is Ronald Demon. It had been sitting on the back burner for some time until he could get funding to launch it. It was featured in Popular Science in 2000. The company was called Vectra Sense. It never went anywhere for awhile but you can see a new mockup prototype of it on their site vectrasense.com
So props to Adidas for elaborating on it and marketing the hell out of it. At least now people will see what is possible with a shoe.
