The Nike React Infinity Run Flyknit 2 ‘Black’ delivers an essential colorway of a performance runner designed to reduce injury through an extra-secure fit and responsive cushioning. Integrated Flywire cables help to contain the breathable Flyknit upper, featuring a plush collar and external heel counter for rearfoot stability. The lightweight construction is supported by a rocker-shaped Nike React midsole, reinforced underfoot by durable rubber in high-wear areas.
