The Union LA x Air Jordan 1 Retro High OG SP 'Chicago Shadow' presents a hybrid design that blends original AJ1 releases from 1985. The majority of the upper is based on the 'Chicago' colorway, featuring a leather upper in white with contrasting Varsity Red overlays and a black signature Swoosh. Separated through exposed zigzag stitching, the collar is lifted from the AJ1 'Shadow,' highlighted by grey overlays against a black backdrop. The lateral side is accented with the iconic Wings logo and a yellow 'UN/LA' label, while a Nike Air tag graces the exposed foam tongue. A pre-yellowed midsole accentuates the shoe's vintage aesthetic.
