Train hard and find your rhythm on the road. From the moment you lace up, the lacing system wraps 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 is combined 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.

The best Nike uppers I've worn and I can say is comfortable, secure and highly breathable. Makes you feel fast and light.

I really love the Fly 4. I have 3 pairs of Fly 4 now (and 1 Fly 3, 2 Pegs, 2 Winflos, 1 Inv since 2021). I ran my first two marathons in them. I run from 50 to 80 miles a week since I started training. I love the propulsion I feel when wearing Fly 4. My only complain is that the heel rubber wears faster than I hope. I run a lot of up and down hills hence unavoidably landing on my heel more frequently than I want. The soft squish Zoom X foam are exposed after about 200 miles. With no rubber protecting them, the Zoom X foam wears fast and it's bad after 400 miles. The Peg holds well in comparison.

These shoes have really good cushion. I have run multiple speed work-outs on a track with these shoes. They are responsive and have good energy return as well. The carbon plate in them also helps me to stay on my fore-foot when running.
