Didn't Jackson lean forward for some reason?

Michael Jackson, a great dancer, has an iconic movement-standing, leaning forward and leaning back. The secret lies in his invention of "anti-gravity dancing shoes", which can make the whole person lean forward 45 degrees without falling down, which is amazing.

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.

The following figure is the bottom view of the whole heel, showing the V-shaped groove at the bottom, which is the core part of high technology.

The protective part inside the vamp for isolating and buffering the friction between the foot and the vamp, or the inner hard layer, plays a supporting role. The thick layer of white socks exposed played a covering role. ?
