No, it's not a running shoe. Nike Air Zoom is a cushioning system designed for speed and agility. This technology uses pressurized air and tightly stretched fibers to help absorb impact. While there are Nike Air Zoom running shoes, the technology is also featured in a range of Nike footwear.

The upper on the Zoom Fly is well thought out and built for endurance. Engineered mesh backed up by Flywire and a padded collar provide a secure fit for your foot. The broad flat tongue takes a little getting used to, but it gives enough protection from the laces without adding more padding or weight.

Conclusion. If your aim is to run personal bests in events and you're looking for a running shoe to use alongside the ZoomX Invincible Run 3, the Nike ZoomX Vaporfly or Air Zoom Alphafly are both great options. If you're looking for a more responsive underfoot feel for daily miles, the Air Zoom Pegasus is a good pick.

The Pegasus, being a neutral running shoe, offers balanced support while promoting a natural stride. Medium cushioning underfoot with two Air Zoom units offers an energetic bounce without feeling too soft.
