The rumors were true: The Eminem x Air Jordan 4 "Encore" is coming back. The sneakers won't be getting a proper retail release, though—according to StockX, only 23 pairs of the 2017 version were produced.

Just one of those, a size 12, will be available exclusively via a charity drive on StockX. There, users can purchase an entry to win a pair of these very exclusive Jordans, and other items from the Detroit rapper's collection, for a donation of $10.

Proceeds from this charity drive will go to the Marshall Mathers Foundation, which provides community support efforts in Detroit and the surrounding areas.

Eminem and his longtime manager, Paul Rosenberg, are investors in StockX, an online reselling platform based in Detroit.

The "Encore" Air Jordan 4, which gets its moniker from Eminem's 2004 album of the same name, first surfaced in 2005 as a friends and family exclusive.
