Streakfly 2

Built for pure velocity over short distances, the Nike Streakfly 2 delivers feather-light explosiveness for runners who specialize in 5Ks, road intervals, and track-speed efforts. Dropping an astonishing 45 grams (1.6 oz) from the original, this update transforms the Streakfly into one of Nike’s lightest road racing tools ever, enabling faster turnover, reduced fatigue, and razor-sharp responsiveness. A full-length PEBA ZoomX midsole boosts energy return while trimming weight, giving the shoe its most aggressive, sprint-inflected feel to date.

Replacing the previous plastic shank, a full-length carbon Flyplate now drives propulsion with greater stiffness and snap, delivering punchier toe-off mechanics at race cadence. Underfoot, the waffle rubber outsole has been precision-perforated to enhance traction while maintaining a near-track-spike lightness. With a 4 mm drop, an aggressive racing posture, and a geometry that encourages forefoot engagement, the Streakfly 2 is tuned for athletes who live in the faster gears.

Its ultra-minimal engineered mesh upper provides a barely-there lockdown to ensure nothing interrupts rhythm or race focus. From 5K PR attempts to interval splits that test limits, the Streakfly 2 is crafted for runners who want uncompromising speed in the leanest possible package.
