Christian Louboutin (born 1964) is a footwear designer who launched his line of high-end women's shoes in France in 1991. Since 1992, his designs have incorporated the shiny, red-lacquered soles that have become his signature. On March 27, 2007, Christian Louboutin filed an application for U.S. trademark protection of this red sole design.
"In 1992 I incorporated the red sole into the design of my shoes. This happened by accident as I felt that the shoes lacked energy so I applied red nail polish to the sole of a shoe. This was such a success that it became a permanent fixture" Christian Louboutin
