Nike Zoom Fly 4: Feel like race day every day 

Made with a carbon-fiber plate sandwiched between the React foam, the Nike Zoom Fly 4 has the frame of a racer but is built for daily training runs. Want to set or beat PBs? It's the speedster that will let you bolt through the streets. 

To find out how, let's dissect the midsole:

  • The React foam provides ultimate energy return and comfort without any bulk. 
  • Complementing it is the stiff carbon plate for a snappy ride.

Nike Zoom Fly 4 vs. 3 

  • Better lockdown: It's easier to tighten the laces because of the 4 individual pieces of webbing that work with the lacing system. 
  • Enhanced support: The combination of the internal heel pod and sock-like wrap of the Flyknit upper, the foot is kept in place. 
  • Increased comfort: Not only is the new upper lighter, it's also a touch softer and more breathable than its precursor.
