Released in August 2020, the Union LA x Air Jordan 4 Retro is a follow-up to an Air Jordan 1 collaboration from 2018. Built with black suede, the upper includes mesh on the toe box and collar. Translucent wings mark the quarter panel, while the classic eyelets appear in black and white. Contrast stitching emerges throughout, while the Air Jordan tongue tag sports an inside-out aesthetic. The side wall includes 'UN/LA' branding, while underfoot, a yellowed midsole contributes to the retro look, with visible Air in the heel providing cushioning.
