Called a “substrait,” Jesse Leyva’s team wondered if they could change this interior color by changing materials. The solution was found by using synthetic materials. The banned banned Dunk Premium uses black synthetic material with various colored interiors to achieve this multi-colored substrait effect. Each panel of the shoe contains a different color which, when the top layer is carefully etched away, is revealed in high contrast by the laser. This season, the motif is the octagon—a symbol chosen by banned’s design team to represent the summer games in Beijing and to honor the power of the number eight in Chinese culture.
