Undefeated, a Los Angeles-based store specializing in sneakers and clothing, showcased their creative prowess by revamping Nike's Air Max 90 in their exclusive four-piece collection for December 2019. To bring a distinctive touch to this iconic silhouette, they incorporated a premium full-grain leather upper, enhancing the overall design. Instantly recognizable as a collaboration, the sneaker's aesthetic is further highlighted by the striking combination of black and blue tones, with co-branding hits featured in Blue Fury. This cool-toned hue seamlessly traces the outline of the shoe, effectively separating the upper from the midsole, and reappears on both the Max Air unit and the outsole.
