The Jordan Why Not? Zer0.4 'Upbringing' is one of the four initial colorways of Russell Westbrook's fourth signature shoe. Paying homage to the athlete's early life in Southern California, artist Chris Burnett, based in LA, utilizes his unique collage-style technique to create a mismatched upper for the mid-top silhouette. This upper showcases vibrant colors and graphic prints that are directly linked to Westbrook's childhood. The shoe also offers impressive performance benefits, including two stacked Zoom Air units in the forefoot and a translucent rubber outsole that is de-coupled and features a traction pattern informed by data.
