The Undefeated x Air Max 90 'Black Optic Yellow' was launched December 2019 accompanying other iterations, the result of a collaboration between Nike and the well-known West-Coast streetwear boutique. Co-founders James Bond and Eddie Cruz have contributed to a number of Nike designs in the past. In this premium collection of the iconic running sneaker designed by Tinker Hatfield, they created four white and four black versions with singular color motifs and UNDFTD branding.
