The Air Jordan 22 (XX2 or XXII) PE - Detroit Pistons (white / metallic silver / varsity royal / vrs) were released on October 6, 2007, retailing for $150. They were part of a regional release, in which each city¡¯s version of the Air Jordan 22 (XXII) was only released in that city. The Air Jordan 22 (XXII) was inspired by the F-22 Raptor Strike Fighter. When you look at the F-22 Raptor you see the sharp aerodynamic cuts that can cut through the air like ice. Some of these characteristics of the F-22 can be seen on the Air Jordan 22 (XXII). This particular edition features the official team colors of the Detroit Pistons, with a white, blue, and red colorway. The side panels feature the Detroit logo written out in small font, along with a red outline of the skyline. Other features include a strap around the ankle area, phylon midsole, as well as an improved and color coded version of the IPS (Independent Podular Suspension) system, previously seen on other models.They allow the athlete to choose his cushioning for each pod with either a responsive, double stacked Zoom Air pod, or a shock absorbing encapsulated air. In addition to the custom fit cushioning the IPS provides, the phylon midsole provides extra cushioning without adding extra weight.
