Christian Louboutin is a french shoe designer who was born in 1963 in Paris. His work is specially known because of the red sole, which appears in every creation he does. The idea came when he saw an assistant painting hew nails in red while he was working on a shoe design. He immediately seized the bottle of nail polish and painted it directly on to the sole of the shoe. Being pleased with the effect, he originally planned to paint all of his shoes with different coloured soles, however, after seeing the popularity of the red soled shoe he abandoned this idea, and allowed the red sole to become his signature.
