The Air Jordan 1 Retro High OG GS 'Obsidian' features a familiar color scheme that pays tribute to Michael Jordan’s alma mater. This grade school edition features the same build as its full-sized counterpart, featuring an all-leather upper with Obsidian and University Blue overlays atop a Sail base. Branding hits include a Nike woven tongue tag and the Wings logo printed on the lateral collar flap.
