In 1991, Nike released the Air Max IV which later known as the Nike Air BW or Air Max Classic to the Air Max line. This iconic shoe boasts an anatomically engineered PU midsole, maximum volume Air-Sole unit in the heel, leather and synthetic upper, and a BRS 1000 carbon rubber waffle outsole.
A variety of Air Max IV appeared in the market in different styles which includes the Nike Air Max Hyperize, a high top sneaker with Flywire technology and full-length Air Max unit, and the Nike Air Max IV Zoom Kobe, a basketball player edition shoe endorsed by NBA player, Kobe Bryant..
Nike also chose the Air Max BW for the NikeiD program as one of the base shoes ready for customization. With this special course, a choice of nubuck, glazed pull-up leather, or mesh is the selection for the upper. Other features present on the Nike Air BW iD are Max Air for maximum impact protection, waffle outsole for traction and additional cushioning, and customizable embroidered personal iD.
The Nike Air BW has been recently adopted for casual wear and its clean lines convey sharp details and distinctive style for everyday outfit. With this model, Nike has not just concentrated with the running field but also with the basketball court and urban streets. Nowadays, the Air Max BW is the best selling Air Max shoe of all time.
