How Do You Make a Racquetball Shoe?

I wanted to use kangaroo leather, but at the time, kangaroos were an endangered species. All of the best shoes in the world for performance were kangaroo. So what a soccer player does is you buy the shoes, a half size or a size too small. And then you come on and get them wet, leave them on your feet. When they dry, you have a shoe that's formed to your foot. Perfect.
