Every day has its own race! Experience the great feeling of starting a race as soon as you slip on the Arcadia 2 from Nike. Get more momentum when you jog, run or sprint with our dynamic Zoom Air cushioning. The improved upper fit ensures a perfect fit, not too tight or too loose, when you're pushing yourself. Dynamic and responsive, the Zoom Air cushioning provides a great sense of momentum. The semi-transparent rubber outsole in the heel reveals the color of the Air unit. The combination of breathable mesh and stretchy fabric conforms to your feet for a comfortable fit. Two hidden elastic straps from the tongue to the arch support provide optimal support. The rubber outsole provides traction and durability when you run. Cutouts under the forefoot add flexibility and lightness. Soft foam provides lightweight cushioning underfoot. The extra layer on the toe and sides provides extra durability in strategic areas.
