A few weeks ago I watched this very interesting piece on Christian Louboutin and shoes in general. It turns out that his idea for the red sole came from his assistant who was painting her nails with CHANEL nail colour. He took the nail polish and tried the color on the sole of one his shoes, and thus the red sole was born. So the question is which one of the Chanel nail colors match the shoe sole color? Another interesting piece of information I learned about his shoes, was that some of his platforms contained another platform inside so the curve of the feet was less steep.
