When you present an Oscar with Michael J. Fox, there's only one way you can hit the stage.
After starring in a Back to the Future bit, Seth Rogen and Fox pulled up to the stage in the DeLorean car from the trilogy. On Rogen's feet, Nike Mag sneakers, famously worn by Fox's character Marty McFly in the sequel.
The auto-lacing sneakers were made available through a Nike drawing last October and have sold for $30,000 - $60,000 on eBay since.
