A collaboration between Nike and the LA-based apparel boutique, the Undefeated x Air Max 90 'Black Green Spark' was released December 2019 along with other colorways. Undefeated co-founders James Bond and Eddie Cruz are long-time Nike collaborators, and in this AM90 pack they created four white and four black sets, each with singular supplementary colors in rich leather. Branding hits occupy the tongue, heel and insole in prominent contrast.
