These guys take pairs of the Nike Free Run and modify them to make sounds. First video below is behind the scenes of how they did it. Watch that before the second video of the actual performance. Had I not seen what they did, I would have thought the video was faked. Enjoy.
Dude that was awesome.
Thought you would appreciate that @Oscar.
This is so cool. Maybe putting this on kids shoes will make the kids want to exercise more.
@Jane..I wouldn’t mind them in mine.
