Experience a revamped favorite with the Nike InfinityRN 4, tailored for a seamless run with supportive cushioning. This innovative shoe introduces the all-new Nike ReactX foam, delivering a remarkable 13% increase in energy return compared to Nike React foam, ensuring a fresh and responsive feel throughout your run. Noteworthy is the commitment to sustainability, as ReactX significantly reduces its carbon footprint by at least 43% in a pair of midsoles compared to Nike React foam. Pairing ReactX foam with Nike Running’s most well-fitting Flyknit yet, the InfinityRN 4 provides secure upper support and optimal breathability, allowing you to take off confidently at any time and in any location. This shoe offers the peace of mind to push your limits, thanks to its intuitive design that supports each stride, enabling you to go faster and farther. The carbon footprint assessment of ReactX is based on a cradle-to-gate evaluation reviewed by PRé Sustainability B.V and Intertek China. Please note that other midsole components, such as airbags, plates, or alternative foam formulations, were not included in the assessment.
