The versatile Nike ZoomX Invincible Run Flyknit 3 delivers consistent comfort, an ideal all-around running shoe for your daily run. Experience ultimate performance every day with the ZoomX Invincible Run Flyknit 3. Midsole In this shoe, Nike ZoomX foam ensures optimal energy return: every step gives you energy for the next. As you run, you feel propelled by the 85% energy return of Nike ZoomX. ZoomX is also lighter and softer than other Nike foam. The shoe has a rocker profile, which refers to the curved design of the sole. This ensures an extremely smooth-feeling shoe, stimulates the transition from the midfoot to the forefoot while running and thus reduces the load on the calf muscles. Upper The upper is made of Nike Flyknit. This is made of strong, yet lightweight yarns that are woven into one whole. Around the midfoot, the material is woven more tightly to provide support, while at the forefoot the material is made flexible and breathable. A knitted upper ensures that the material can be stretched with the foot in all directions and provides a high level of breathability. Instead of laces, this shoe uses Flywire technology, which uses high-tensile threads that function to provide ultimate precision support. Outsole The shoe's rubber outsole provides good grip and traction while running.
