Do hover shoes work

if u go to 'YouTube.com/watch?v=40S8G2ZuRpE&NR=1">http://www.YouTube.com/watch?v=40S8G2ZuRpE&NR=1 ' u can see how to make them but they have some things that wouldn't really work

a magnet is pulled to metal witch ever way you put it and in this video your heels r higher then your tows WRONG your heel ways more than your toes so it would be in the air and if u can see the shoes are all you see not the person or anything else
