Jackson and two fashion designers left a hook position at the heel of the special shoes. When he needs to lean forward, a row of hooks will rise on the stage. At this time, the stage will create other visual effects to attract the attention of the audience. Jackson and the dancers will take the opportunity to slide the heel onto the hook and buckle it, and then perform a forward performance. Of course, even so, it is inseparable from the hard exercise, careful rehearsal and running-in of dancers such as Jackson, as well as strong back muscle and body balance control ability.
Michael Jackson and two partners obtained the patent of 1993 for this invention. Aaron Kwok also performed in concerts, and he also made a special trip to the United States to ask Jackson for advice.
