Nike Invincible 2

"TRAIN HARD, KEEP RUNNING. Push yourself to the limit when you run. The Nike ZoomX Invincible Run Flyknit 2 keeps you running with the same super soft feel that lets you feel the potential when your foot hits the pavement. We designed the shoe with plenty of springy responsiveness and our highest level of support to keep you feeling confident and competitive. It's one of our most intensely tested shoes, and it's still designed to keep you on course. Secure, cushioned comfort. Three Flyknit components have been placed in different areas of the shoe. Seamless construction at the tongue provides soft cushioning and an adjustable fit. The leather upper is soft and provides an extremely secure fit. Finally, the heel is designed with a clip for support and cushioning. The result is an upper that provides comfort and stability while you hit the sidewalk. Higher, Softer, Wider The increased foam height ensures a softer feel. The wide, pronounced shape at the toes provides a more stable running feel. More cushioning Nike ZoomX foam is responsive and lightweight, providing a springy feel with every step. The foam has a curved shape, providing support during all three phases of the stride cycle. It provides flexibility as the foot disengages from the ground, a smooth running feel as the foot moves forward, and cushioning during ground contact. Traction based on data The outsole is based on data from running to provide traction in key areas. This data was also used in the design and look of the shoe's sidewalls."
