While we reported the release of the Slam Jam x Nike Air Force 1 overseas, the collection is finding its way stateside. Proper of Long Beach, CA is among select U.S retailers who have released these Air Force 1s. If you missed our earlier posts, the project consists of four colors which feature wrinkled patent leather uppers complimented by white accents and embossing at the back heel. The red and grey models are now available at Proper now.
