If you've ever had occasion to wonder what the "BW' stands for in the Nike Air Max Classic BW name, the answer may disappoint you. The 1991 shoe, developed by Nike design legend Tinker Hatfield, featured the same Nike Air-Sole unit as the Air Max 90, but its enlarged window would lead to the "Big Window" moniker. While the name wasn't particularly inspired, the shoe's introductory colorway, cloaked in black with hits of Persian violet, would make it a favorite among both long distance runners and '90s-era R&B recording artists. In Europe, the shoe would become a fixture in the hip-hop and rave scenes on both the continent and in the UK. That original colorway is now set to return on March 8, preceded by assorted colorways of the updated Air Max BW Ultra on March 3, featuring a two-tone mesh upper and a lightweight cored midsole.
