The Nike Air Jordan Retro 15 was released in 1999/2000. Air Jordan 15 Retro is the first shoe after Michael's retirement. The design of the Jordan XV Shoes originated from the air craft X-15 which was developed by NASA during the 1950's and was, to say the least, a bit radical. The tounge of the shoe was sticking out in a style that very much made your thoughts go directly to Michael himself and his tounge sticking out. The sides of the shoe were in a woven pattern.
