It's a great impromptu trick but can only be done on shoes with long laces.If you perform it
flawlessly,which isn't hard to do with an hour or two practice, they will be baffled and won't
forget what they just saw for a long time. I like it because it's not cards or coins and you don't
need anything to do it. Just a pair of shoes. How simple and organic is that? Paul Harris is a
genius. Get it.
