In the choreography of Smooth Criminal (1988), Michael Jackson introduced the famous "Anti-Gravity Lean" (the 45-degree lean).
To achieve it live, he used special shoes with a slot that hooked onto bolts in the floor.
So the shoes made it possible, but skill made it look effortless because it’s requires; strong core muscles, precise timing, balance and training
The touching moment Michael Jackson asked his security to let a woman come close because she only wanted to hug him. The way he softly said, ‘Let her, let her. She won’t hurt me,’ was so pure 😭🥹
