Size 9 - Nike Air Max 97 Ultra '17 Zebra. The Nike Air Max 97 may have debuted full-length Air cushioning, but the design of the upper was just as revolutionary. Designer Christian Tresser took inspiration from the concentric lines caused by a single drop of water, while the sneaker’s iconic ‘Silver Bullet’ colorway gave the nod to ‘90s mountain bikes. Today, the legacy of the Air Max line is told through new releases, collaborations, and an annual celebration known as Air Max Day.
