Why is there white cloth on Michael Jackson's shoes?

Although your question is not specific enough, you can guess a thing or two. Do you mean the shoes that MJ wears when he performs smooth crimes at concerts (such as historical concerts or dangerous concerts)?

If so, I can tell you here that strictly speaking, they are not leather shoes, but high-top leather boots. The white cloth you see is the top part, and there are still some in your pants, but it is not exposed. This boot is patented by MJ, and there is a groove at the bottom of the shoe to lock the mechanical device on the stage, thus completing a 45-degree tilt.

In a common German history concert, it can be clearly seen that the only white dancer almost failed to open the organ in time after completing the action, which is why. Because MJ and the dancers wore the same boots in that song. Also, in some amateur concert versions, it can even be seen that MJ didn't fasten the organ properly, which made it impossible to complete a 45-degree tilt or fall.
