Nike Zoom Fly 4 W - 400

DURABLE SPEED MADE FOR PROPULSIVE TRAINING.
Take it to the streets and find your tempo. From the moment you lace up, the webbing on the upper and lacing system wrap around your foot for a secure feel from start to finish. The added flex feels highly responsive and secure with every step. A soft, breathable upper combines with a stretchy collar for a sock-like fit and a secure, stable sensation. You've got goals to hit, lace up and fly towards a new best.

Snug Fit
Nike Flyknit is placed around the collar, providing extra stretch for easy on and off. It has a sock-like feel that helps contain your feet.

Cooler Comfort

Lightweight mesh gives you a softer, more breathable feel that conforms to your feet.
Secure Feel
Midfoot support arrives courtesy of 4 individual pieces of webbing that intertwine with the laces. When you lace up, the shoes get tighter for a stable sensation. Also, an internal heel pod delivers a more secure fit than the Zoom Fly 3.
Propulsive Miles
Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. It combines with an internal carbon fiber plate for better flexibility in your stride.
