The Airwalk

The duo known as Shuffle Pack demonstrate the dance called the airwalk. It's darned cool when they get to it, as they appear to float in the air slightly above ground level. Ignore the reference to a "stranger;" they do that all the time. Shuffle Pack consists of 14-year-old British twin brothers Alex and Alister, so they are always in tune with each other. 

The dance itself is an illusion. What's happening here is a classic example of misdirection, like a magician would use. Your eye is drawn to the part of the dance step that does not touch the ground, while the dancer's weight is supported by the other foot at that time. Their tutorials make it look easy, but like the moon walk, the final appearance depends on how smoothly you pull it off. They say that this will really strain your leg muscles if you do it for more than a few seconds at a time.
