Gisele Bundchen is scared of high heels.

The Brazilian beauty - who is the world's highest paid supermodel - will no longer wear tall shoes on the catwalk, according to designer Nicolas Ghesquiere, who claims more and more models are refusing to walk the runway in heels.

He told NY Magazine: "The idea was to have this crazy casting with Gisele Bundchen and Amber Valletta and Carolyn Murphy and they said no for high heels.

"They were not used to walking in heels anymore. Gisele was worried, she would not walk in my heels."

Gisele, 31, has graced the covers some of the world's biggest magazines, including Vogue, Elle and Esquire and posed for fashion houses including Missoni, Dior and Dolce & Gabbana.

Earlier this year, she was named the world's top earning model for the seventh year, taking $45 million over one year.

In March 2010 she was named the face of hair care brand Pantene and the company's sales went up by 40 per cent in Latin America as a result.
