@wellnes.by.daily: Michael Jackson’s impossible anti-gravity lean wasn’t wires — the secret was hidden inside his shoes. The famous move became one of Michael Jackson’s most recognizable illusions: his entire body appeared to lean forward at an extreme angle while his feet remained planted on the floor. For live performances, Jackson and two collaborators developed a special footwear system that was eventually protected by U.S. Patent 5,255,452. The patent described shoes with a specially designed heel containing a slot that could engage with a hitch projecting from the stage. Once the heel locked onto the mechanism, the performer could lean dramatically farther forward than would normally be possible without falling. But the shoes didn’t magically do all the work. The move still demanded considerable strength through the legs, core and ankles to keep the body rigid and return upright safely. Jackson had originally performed the lean in the Smooth Criminal music video using a different special-effects setup, but that approach wasn’t practical for live shows. The patented system helped transform the illusion into something he could perform directly in front of an audience.
