The Air Jordan 9 was the first signature sneaker that Jordan never wore during a regular-season game. The shoe came out during the 1993-94 season, which MJ had suddenly retired before the start of. The Jordan Retro 9 borrowed design inspiration from the baseball cleats MJ wore during his stint in minor league baseball, making it a unique look and playing into the historical significance of the shoe. It's a historic, iconic look that pays homage to one of the most interesting parts of MJ's career. Minimalist upper that combines leather and nubuck materials.
