This move does what it says on the tin, you are pretending to shine your shoes, so it's as much mime as it is dance and has a strong historical context.
You begin by presenting the foot, lean back and wipe the hand across as if polishing your shoe. You can the hop jump to switch sides to clean the other shoe (cause you'd look odd with just one shinny shoe!) and again flick the hands 4 times as if cleaning your shoes. This is a great move to master, so try it around the house or next time you shoes need cleaning!
