Christian Louboutin is suing Yves Saint Laurent for their use of red soles. This comes without surprise - everyone knows red soles belong to Louboutin and Louboutin only!
The company trademarked the red sole in 2008 and has reportedly asked YSL to refrain from using their signature colour.
This doesn't come as a surprise - in 2007 the label sued Oh Deer! for their use of the red soles.
