Speed is Russell Westbrook’s 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.

Double-Stacked 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.
Locked-In Lacing
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.
Fast-Action Traction
The durable rubber outsole has a new, data-informed tread pattern. It helps keep you low to the ground and ready to react to the game's changing tempo.
The outsole is split into sections to help reduce weight by using less rubber underfoot.
