Winning starts with Russ's engine, an inner drive to be number one at all costs. No matter who the competition is, for Russ that race is non-stop. The rubber-burning speed and zeroed-in focus of someone with this type of motor are not enough alone to win, but require a team that together work like a well-oiled machine. Drawing inspiration from the legendary Indianapolis motorsport competition and iconic racing suit designs, the Jordan Why Not? Zer0.4 'Marathon' celebrates Russ's will to win and the belief that success stops at nothing. Double-Stacked Attack 2 stacked Air Zoom units in the forefoot deliver the ultimate responsiveness and cushioning. They help optimise 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.
