In 1992, Christian Louboutin created ‘Pensée’, a shoe influenced by Warhol and the Pop Art movement. Having drawn the shoe perfectly, he was still disappointed with the prototype. Although it was very close to the initial drawing, something was missing. While staring at the prototype he noticed his assistant painting her nails at her desk. He grabbed the red nail polish and proceeded to paint the sole of the shoe. ET VOILA! The signature red sole was born.
