Proving that it pays to be part of PPR, Puma continues to snag the best designers for their collaborations, now adding the Yves Saint Laurent label to a roster that has included Jil Sander, Neil Barrett, Mihara Yasuhiro and Alexander McQueen. The shoes are going to be sold exclusively online and in YSL boutiques, but there's no word yet on when they're going to be available. I'm already imagining myself in the virtual queue for these.
