Nike Infinity Run 4 - White/Black-Bright Crimson

The Nike ReactX Infinity Run Flyknit 4 uses new ReactX foam, which offers 13% more energy return than the previous version, with a 43% lower carbon footprint, for a more sustainable, and more efficient stride. That midsole is shaped for efficiency and support, with a curving outsole to rock you through the transition, and a geometry with tuned support and focused cushioning. The upper also provides a stable and secure fit, as well as giving Nike Runnings best fitting flyknit yet. At the toe, a liner provides a water repellent finish. Finally, a waffle outsole with increased rubber provides improved durability and traction. Put together, these components make a more environmental, more efficient, and more comfortable feel that has the durability to last all the miles you will want to put into them.
