Christian&Nbsp; Louboutin&Nbsp; Red Shoe To Sue YSL For Commercial Infringement.

(Christian Louboutin)

"The bottom of the red shoes began in 1992," HarleyLewin said. "It is an obvious feature of the Louboutin design, which has been registered in the United States in 2008."

ChristianLouboutin asked the judge to order immediate suspension of the sale of shoes.

Red bottom women's shoes are popular among many celebrities. They have become the signboards of ChristianLouboutin.

But the tradition of wearing red shoes is a long tradition: in France, Louis Xiv wore leather shoes with red heels.

This tradition even dates back to ancient Rome.

In the appeal, ChristianLouboutin said, "the fame of ChristianLouboutin brand red shoes originated in 2009, when the company launched a commemorative edition of Bobbi doll 50th anniversary with MATTEL Mattel. The three dolls that were produced in that year were all wearing red leather shoes."

The plaintiff also asked the defendant to pay a mental loss of $one million.

HarleyLewin said, "Yves Saint Laurent's sole is a kind of piracy.

This can lead to confusion among customers.

A shoe does not need 100% to be a counterfeit.

Yves Saint Laurent Paris head office declined to comment.

The judge has asked the two sides to prepare for the court statement.

Another Brazil brand also has disputes with ChristianLouboutin.

A few months after the CarmenSteffens brand opened in Paris new store, it received a letter from Louboutin, accusing it of using red shoes in some styles.

The Brazil brand "has always had design and production of colored soles, some of which are red," brand France chief said on Monday.

"Our time to use red soles is much earlier than that of ChristianLouboutin.

We are ready to turn out the previous product catalogue as evidence.

"And when he opened a shop in St Paul, Brazil, in 2009, he saw the design of our sole, but he did not prosecute."
