Eminem will design and autograph eight models of Nike Air Max shoes for an auction set to benefit the Marshall Mathers Foundation and NineMillion.org.

"We're always looking for new ways to try to raise money and awareness for the foundation, so when Nike approached us we jumped at the chance," Eminem said in a statement. "When we got the info on NineMillion.org, it made even more sense. Who wouldn't want to design their own line of Nikes? And to do it for charity makes it that much better."

A total of 64 pairs of Shady-designed sneaks will be available during the month-long auction that begins Thursday. Bids can be placed at Nike stores and on eBay.
