Don't Step on His Red Louboutins!

Shoe designer extraordinaire Christian Louboutin is reportedly suing fashion house Yves Saint Laurent, claiming copyright infringement.

Louboutin's perfect pumps are noted for their red soles but YSL has created four distinct styles of shoes ("Tribute," "Tribtoo," "Palais," and "Woodstock") designed with...red soles! Sacré bleu!

The collection is being sold at all the major high-end department stores, including Saks, Barneys, Nordstroms, Neimans and Berdorfs.

According to the suit, the "Defendant's use of red footwear outsoles that are virtually identical to plaintiff's Red Sole Mark is likely to cause and is causing confusion, mistake and deception among the relevant purchasing public as to the origin of the infringing footwear.”

Christian, who registered the red outer sole with the U.S. Patent and Trademark Office in 1997, is seeking over one million dollars in damages. That's a whole lotta shoes.
