The Nike Zoom Vaporfly 4% Flyknit releases on October 4th at the Distance Lab.
Eliud Kipchoge, the fastest marathoner ever, has called Nike’s 4% system "perfect...really perfect.", more than half of all 2018 Marathon Major podium finishers had the Nike Zoom Vaporfly 4% on their feet, and the shoe is getting even better.
Nike has upped the ante with a new 4% option that provides an even lighter, more breathable upper: The Nike Zoom Vaporfly 4% Flyknit.
The Nike Zoom Vaporfly 4% Flyknit got a new upper, but the revolutionary technology that is the hallmark of the 4% system hasn't changed. Created in conjunction with Breaking2, the Nike Zoom Vaporfly 4% was designed with the goal of helping the world’s fastest marathoners run their best. It features Nike ZoomX foam (which is ultra-lightweight, soft and capable of providing up to 85-percent energy return) and an embedded full-length curved carbon fiber plate (that increases stiffness to provide a sensation of propulsion). Together, this delivers an average of 4-percent improvement in running economy when compared to Nike’s previous fastest racing flat.
The Nike Zoom Vaporfly 4% Flyknit will retain these revolutionary features with a one-piece knit upper that seamlessly hugs and supports the foot.
