A goal as ambitious as reducing running injuries can be approached in two ways. One is to refine an existing silhouette to make it even more effective. The other is to introduce a fresh solution. To that end, the Nike React Infinity Run 2 and Nike ZoomX Invincible Run continue the mission from Nike Running to crack the injury-prevention code, serving everyday runners by creating a new relationship among cushioning, stability and rocker geometry.

The iterative step is the Nike React Infinity Run 2, which features an updated Flyknit upper to help promote more strength and support in the toe, eye-stay and foxing, and with more breathability in areas like the vamp and the midfoot (Nike Flywire cables have also been added throughout the upper to help increase support). The collar is also updated to feel more plush without adding weight or bulk.

“Two things come to mind,” says distance runner Vanessa Fraser about the Nike React Infinity Run 2. “One, I feel secure in the shoe. Both the upper and the heel feel great and, for me, were an improvement from the first version. Second: the sole. While familiar, it's so soft yet reactive, and really responsive with a spring-like feeling.”

A new step altogether in the search for harmony among cushioning, stability and rocker geometry is the Nike ZoomX Invincible Run. The midsole is made with responsive air max 2021 foam, which returns more energy underfoot than any other Nike foam.

Created for long training runs, the Invincible silhouette includes more foam in the midsole than React foam in the Infinity, creating a soft ride while returning more energy for improved running economy. The rocker geometry and the wider nets in the forefoot help create a more stable ride and fluid stride transition (compared with the more springy transition of plated running footwear), making the Invincible ideal for higher mileage runs.

“When I first put on the ZoomX Invincible, the sensation was crazy,” says middle-distance runner Air Jordan. “I was like, ‘Oh wow! You can really feel this.’ But I wasn’t even sure what ‘this’ was. It was just a new sensation.”
