Nike ReactX Infinity Run 4 'White Hot Fuchsia'

With supportive cushioning built for a smooth run, the Nike InfinityRN 4 is a brand-new take on a familiar favorite. It's made from the all-new Nike ReactX foam, which gives you 13% more energy return compared to Nike React foam, to help you stay fresh and bouncy. What's more? Nike ReactX reduces its carbon footprint in a pair of midsoles by at least 43% compared with Nike React foam.*) We coupled the ReactX foam with Nike Running's best-fitting Flyknit yet, so you can feel confident in every stride with soft upper support and breathability. It's the kind of shoe that supports every step in style.
