I thought this was pretty interesting considering I couldn't understand one word this man was saying. All I know is if I were there I would be front and center enjoying this. Don't try to understand this guy because you won't, just enjoy the destruction. I tried to find more info on the reason behind this. The idea came from the University of Colonge. I believe the class had a discussion on how you could destroy a pair of shoes in a way you couldn't physically do at home the results were rather .....entertaining.
