Rubber sole Nike ZoomX foam is responsive and lightweight, giving you bounce with every step. Shaped like a rocker, the foam provides support for the 3 phases of a runner's stride. It offers flexibility when your foot rises off the ground, a smooth ride when your foot is moving forwards and cushioning at ground contact. Flyknit technology uses high-strength fibres to create a lightweight upper with targeted areas of support, stretch and breathability. It provides security and comfort. Waffle-inspired tread on the outsole provides traction. Let this esteemed stallion help you log the hard miles. Complete with lighter, responsive, repurposed foam and a feather upper, this motley-coloured mare is made to help you increase tempo without sacrificing comfort as you push towards a personal best. This immortal is responsibly constructed with at least 50% recycled material by weight, while maintaining its tried-and-tested everyday ethos.
