Nike Zoom Fly 4

DURABLE SPEED MADE FOR PROPULSIVE TRAINING.

Train hard and find your rhythm on the road. 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 for a secure, stable sensation. You've got goals to hit, lace up and fly towards a new best.

Snug Fit

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

Cooler Comfort

The upper is made with lightweight mesh for a softer, more breathable feel that conforms to your foot.

Secure Feel

Midfoot support arrives courtesy of 4 individual pieces of webbing that intertwine with the laces. When you lace up, the shoe gets tighter, giving you stability. 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 flexibility in your stride.
