The Nike Shox O'Nine model follows a long line of Shox releases since 2001 that have always delivered performance, style, and comfort. They feature a combination leather/synthetic leather upper, rubber midsole with internal flex-grooves, and a rubber outsole with a Nike Shox-inspired pattern. Although you can always count on performance features from Nike Shox models, the Nike Shox O'Nine also sports a very stylish striped design.
