Nike recently released another video installment of their ongoing Inner Strength series featuring Belgian striker Romelu Lukaku. But hidden in the workout regiment was a brand new training model – the upcoming Nike Train Ultrafast Flyknit. The Swoosh has been aggressive about pushing all-purpose trainers, and here the Ultrafast showcases that capability thanks to a chainlink Flyknit construction that offers up responsive lockdown comfort atop a low-profile midsole. They even hint at what the brand is calling a “responsive propulsion plate underfoot” to continue the theme of stability and traction on top of multiple playing surfaces. The previews of the upcoming model are brief, but check them out below and stay tuned for a release later this summer.
