It is common knowledge that for the famous anti-gravity move in the Smooth Criminal video , which was patented in 1993, Michael Jackson wore special shoes with hook-shaped inlays on the heels.
During the show, pins were stuck into the stage floor at the places where Michael and the dancers were performing.
When Michael and the dancers are positioned directly above the pin, the heels of their shoes automatically engage and create a stable anchor point that allows them to lean forward without losing their balance.
But,
Despite Michael Jackson's genius thinking that led to the creation of this movement, tilting the body like that is not easy.
This kind of tilt requires a lot of physical strength, especially in the back, calves, and abs, to maintain the position and get back up without falling.
Thanks to a combination of technique and extensive athletic training, Michael Jackson and his dancers successfully leaned forward at a 45° angle. Yes, a movement impossible for the human body to perform without support.
