I came to know about this amazing fact recently through a documentary.
Most people don’t know that Michael Jackson actually had a patent on effects used in conjunction with his moonwalk. He along with Michael L. Bush and Dennis Tompkins invented this shoe in 1992.
A system for allowing a shoe wearer to lean forwardly beyond his center of gravity. The shoes have a specially designed heel slot which can be selectively engaged with the hitch member by simply sliding the shoe wearer’s foot forward.
