How to make Michael Jackson's 45-degree diagonal shoes?

There is a catch hook on the back, which is connected to the heel with a rope, and there is a mechanism behind the shoe, which cooperates with the floor. When walking to a specific position, the grab hook extends out in time. During the performance, one person threw ammunition on the stage to attract the attention of the audience. MJ takes the opportunity to prepare, then tilts 45 degrees, the action is completed, and the grapple is retracted. During the performance, MJ will bear the weight of 145 kg on one leg. Very impressive.
