Michael Jackson did many great things during his lifetime, but one thing he actually did that not too many people are aware of is that he patented an anti-gravity boot. These are the boots that allowed him to lean really far in the music video Smooth Criminal, which allowed him to defy gravity.
Here is the actual patent pertaining to his famous anti-gravity boots.
“A system for allowing a shoe wearer to lean forwardly beyond his center of gravity by virtue of wearing a specially designed pair of shoes which will engage with a hitch member movably projectable through a stage surface. The shoes have a specially designed heel slot which can be detachably engaged with the hitch member by simply sliding the shoe wearer’s foot forward, thereby engaging with the hitch member.”
