STAY GROUNDED, FLY FAST.
Speed is Russell Westbrook not-so-secret weapon. He continually out-hustles the competition, building momentum and muscling his way onto the highlight reel. Cue the Jordan Why Not? Zer0.4, the first to feature double-stacked Zoom in the forefoot. It's an extra-responsive cushioning system that's designed to help him transform speed into force and focus his attack.
2 stacked Air Zoom units in the forefoot deliver the ultimate responsiveness and cushioning. They help optimize the energy return you get out of every step.
The laces combine with strips of webbing in the heel and forefoot. When you tighten the laces, the material engages to help you stay harnessed over the cushioning.
The extra-durable rubber outsole is designed to play on outdoor courts. It's got a new, data-informed tread pattern that's designed to help keep you low to the ground and ready to react to the game's changing tempo.
