Nike ReactX Infinity Run 4 Black Anthracite

The Nike ReactX Infinity Run 4 Black Anthracite updates the Infinity Run 4’s road running silhouette with a sleek black-on-grey colorway.

Designed for running on paved surfaces like sidewalks and roads, this version of the Infinity Run 4 features a rocker-shaped midsole that houses Nike’s signature ReactX foam. This cushioning system delivers elevated energy return while protecting against impact stress. Additionally, the waffle-patterned outsole provides traction on various urban surfaces. At the Black Anthracite Nike ReactX Infinity Run 4, the upper is constructed from durable Flyknit, a breathable synthetic material that supports the foot without adding additional weight. Finally, the sneaker comes with a water-resistant membrane, though it isn’t fully waterproof.

Our StockX experts appreciate the way the sneaker commits to its ultra-dark colorway—even the Swoosh logos and the tongue’s Nike branding come in Anthracite. The Nike ReactX Infinity Run 4 Black Anthracite was released on August 3, 2023, and sold for $160.
