Kari Sigerson and Miranda Morrison quit their design jobs at their eponymous shoe brand on March 15, twenty years after they co-founded it in 1991. Neither the designers nor the label's parent company, Marc Fisher Footwear, will discuss details of their departure, but it's probably related to yesterday's announcement that the line is getting an overhaul, complete with different price points for both the signature collection and the diffusion line, Belle.

Marc Fisher president Susan Itzkowitz says that the company already has a new design team in place. Meanwhile, Sigerson and Morrison say that they'll stick together and are seeking new business opportunities that "will almost certainly involve shoes," said Morrison. Their final collection for the label will be the fall 2011 line.
