The EX89™ sneaker from the SHIGEN 2.0 Pack blends the heritage of the GEL-EXTREME™ basketball shoe from 1989 with influences from Japan's recycling practices. It features a consistent shade of blue that references the color of the country's trash cans and garbage trucks throughout the design.​ Its upper construction features a woven material on the underlays that's formed using recycled PET and textiles. These elements are offset with a net-like mesh that appears on the overlays. The outsole’s pattern is meant to mirror the view of a city from the sky. This functional grip feature was initially inspired by the designer’s first business trip to the United States in 1987.
