The Vomero 18 is an all-rounder designed by Nike for your daily run. With the Vomero 18 you have a perfect mix of comfort, support and durability. Take on your running challenge with the Vomero 18. Midsole This shoe offers excellent cushioning thanks to a combination of Nike's ZoomX foam over the full length of the shoe and ReactX foam in the heel and forefoot. ZoomX provides 85% energy return, so you feel like you're being propelled while running. In combination with ReactX foam, this makes for a very responsive and comfortable running experience. A Zoom Air unit is built into the midsole of this shoe, which absorbs impact and then quickly bounces back, reducing the stress on muscles, joints and tendons. Zoom Air units allow you to run faster and jump higher because they transfer energy more efficiently. Upper The upper of the Vomero 18 is made of mesh for good breathability. Outsole While running, the shoe offers good grip and traction due to the rubber outsole.
