Nike Streakfly 2

Features:

Carbon fiber and ultralight foam power your race day speed. The Streakfly 2 can help you out-kick the opposition on race day. This speedster now comes with a carbon fiber Flyplate, complementing the ultraresponsive ZoomX foam midsole and minimal upper you loved on the original. From the 10K to the mile, it can help you take your distances to the next level.

Full speed.  Nike integrated a full-length carbon fiber Flyplate that delivers a propulsive feel. It helps you smoothly transition through every stride and tackle turns with confidence.

Optimal responsiveness. ZoomX foam, Nike's most responsive foam, provides optimal responsiveness. The result is a shoe so light, it feels like it disappears on your foot while still helping you reach your fastest pace.

Sticky outsole. The outsole is made of a thin, sticky, webbed substance that helps reduce the weight of the shoe while still providing optimal traction.
