Thoughtfully designed, the Nike SB Koston X Heritage merges two silhouettes, the classic Nike Air Max 90 and the new Eric Koston 1, as one. But it isn’t just an experiment in visual argumentation. Skater Eric Koston and the design team at Nike Skateboarding went ahead with the change only after they were sure it will not jeopardize performance. Still very much a Eric Koston 1 in appearance, the Nike SB Koston x Heritage features several design cues from Nike Air Max 90, such as the sidewall tab, eyelet details, and of course, the heel plate. It also features a skate-friendly outsole tread and a removable Lunarlon insole for cushioning.
