The Nike React Infinity Run Flyknit 3 Triple Black is a running sneaker featuring Triple Black’s monochrome aesthetic. Nike has been at the forefront of sneaker technology since the 1980s, when it introduced Air Max technology. With Nike React technology, the brand utilizes a lightweight yet durable foam for a smooth and responsive wear. The React’s rocker shape and flexibility aid in supporting the three phases of a runner's stride. The black Flyknit upper has an adjustable tongue. Nike Swoosh branding in shiny Black accents the sides. The Black foam midsole has a wide silhouette, accented by an embossed Nike Swoosh, and black laces tie the look together.
