Christian Louboutin's fabulous red bottom sole began in the most interesting way. After designing a shoe and receiving a prototype, Louboutin was so disappointed with the shoe, but couldn't figure out why. His assistant was painting her nails red, and he proceeded to grab the polish and paint the bottom of the shoe. Welcome to the signature red bottom sole! Christian Louboutin has now ventured into the world of beauty with his signature polishes. The Noirs.
