The effect in the video when Jackson and the dancers lean forward a seemingly impossible distance was achieved using special harnesses with wires and magnets. It was desired to replicate this effect for Jackson's stage show, but it would have been more obvious and cumbersome to use wire harnesses in a live performance. Jackson and his team devised an alternative way to achieve the effect on stage. The props needed for their technique were patented in the United States by Jackson in 1993, and consist of pegs that rise from the stage at the appropriate moment, and special shoes with ankle supports and cutouts in the heels which can slide over the pegs and be thereby attached to the stage temporarily. These allow the performers to lean without needing to keep their centers of gravity directly over their feet.
