Michael Jordan donned the 6 on his way to his first NBA title in 1991, when it was initially introduced. The shoe was retroed for the first time in 2000, with new colours and Jumpman emblems replacing the original "Nike Air" branding. It returned in its current form in 2009. The Jordan 6 has been consistently ranked as one of the best basketball shoes of all time by various publications. It is known for its low-top design, which is popular among players and coaches who prefer not to wear socks. The shoe also gained notoriety for its advertising campaign that featured Michael Jordan wearing the shoe in a series of commercials directed by David Fincher. The shoe has been available in several colour combinations over its lifetime, including black/white, blue/black, red/black and grey/black. A white version was also released in 2000. A total of eight models of the Jordan 6 have been released throughout its existence, with the latest being the MJ1, which was announced in 2009. The shoe continues to be produced today, with minor changes made to the design each year. The average lifespan of a sports car is about 5 years. The Jordan 6 has been available for almost 20 years now, so we can estimate that it will become obsolete around 2020 or 2021.
