The Union LA x Air Jordan 1 Retro High OG SP 'Chicago Shadow' combines two OG colorways. Part of the upper is based on the original 'Chicago' colorway, using a white leather upper with contrasting red overlays and a black Swoosh. Separated via exposed zigzag stitches, the collar borrows from the AJ1 'Shadow,' complemented by grey overlays on a black background. The opposite side gets a Wings logo and a yellow 'UN/LA' label, while a Nike Air tongue tag adds to the signature look. A vintage-style midsole finishes the look.
