Nike just introduced its newest running sneaker that is not only capable of providing high-level performance, but is also better for the environment.

Shown here is the Nike InfinityRN 4, which is the first sneaker to feature the brand's new ReactX foam cushioning. According to the brand, the ReactX foam took over five years of reseaerch and development before the brand finally landed on an ideal spot between performance and environmental impact. ReactX reduces its carbon footprint by 43 percent as compared to the brand's standard React foam due to improvements in the manufacturing process but also provides a performance benefit with an increased energy return of 13 percent compared to React.

The silhouette also features a new Flyknit material on the upper that uses an average of 60 percent less waste than traditional manufacturing of the uppers. Rounding out the design is the unique rocker design on the outsole that provides flexibility during the initial push off, a smooth ride during each step, and maximum cushioning upon landing.

"Athletic performance and impact on the planet aren’t mutually exclusive," Bret Schoolmeester, Nike’s senior footwear director, said. "Our goal is to make athletes better and make the planet better for athletes. With materials representing about 70% of Nike’s total carbon footprint, innovating new, more sustainable materials is a top priority and we’ll do that, while delivering better performance."

Readers can cop the Nike InfinityRN 4 at Nike.com and at select Nike Running retailers starting in August.
