Apparently he actually had a special shoe to enable these insanely unique moves.  Katie Couric shows us in the video below.  Would you have every guessed that?  Not to mention the shoe was actually patented.  So aside from being an extremely talented performer, he was very clever and/or had very clever advisors.

One of the commenters disagrees:

I don’t believe its the shoes.  His body and muscule are doing the thing’

What do you think?  Is this just an emotional response by a super fan or was it only the patent?  Or perhaps a bit of both.
