Verdict from 11 experts and 9 user reviews

10 reasons to buy

  • Comfort: Runners praise the Invincible Run's midsole, describing it as squishy, greatly soft, and ultra-comfortable. So much so that they claim it's one of the most cushioned rides they've ever experienced. 
  • Bounce: Reviewers are in awe with the shoe's springy, propulsive ZoomX foam, saying that every stride feels effortless without losing control. To give you an idea, they say it's "pogo-stick-on-a-trampoline bouncy." 
  • Stability: Although not as stable as the Nike React Infinity Run 2, the shoe's wide forefoot and heel sections allow for surefooted steps, even on downhill runs.  
  • Heel clutch: There are no reports of heel slips. The collar is padded sufficiently, locking the foot in place. 
  • Lightness: On the run, the shoe feels lighter than its actual weight. 
  • Toe box: It has enough volume and space for swelling and toe splay. Some of the experts even go far as saying that "you need hobbit feet" to feel restricted in it. 
  • Flexibility: Up front, the shoe has sufficient flex for an agile toe-off. 
  • Fit: It may be snug but it's not as constrictive as other Flyknit shoes. It stretches enough to accommodate the foot. 
  • Traction: Several reviewers are surprised by the shoe's grip, especially on damp pavements and corners. Some of them even say that it "held well on icy surfaces." 
  • Gusseted tongue: Because of this, the tongue does not move side to side and stays well-centered.

2 reasons not to buy

  • Questionable durability: After just 30 miles, there's already some visible wear on the outsole. Experts estimate that it will not last 300-400 miles. 
  • Skin rubbing: The padding on the lateral ankle collar digs into the foot (just below the ankle bone).

Bottom line

The first Nike trainer with a full-length ZoomX foam, the Invincible Run hits home for entry-level marathoners and seasoned athletes alike. It's light and cushioned enough to save the legs for the last-mile stretches and is a perfect training companion for runners who want an "ultra-comfortable, soft, and bouncy" daily trainer. 

It might seem like the perfect shoe for speedwork with all its qualities, but it's not. On the contrary, it's an excellent fit for long and easy runs.

Nike ZoomX Invincible Run: An answer to the runners' requests

When the Vaporfly was introduced, many athletes were stoked about it and wondered what it would feel like to have a plateless version (no carbon-fiber plate) of it. Some iterations later, Nike comes up with the ZoomX Invincible Run, which they position as a premium high-mileage daily trainer. With its plateless design and softer ZoomX cushion, it is definitely a training complement to its racing siblings — Vaporfly and Alphafly.

If you're looking for a speed-day option, Nike is upfront that the Invincible Run does not make you run faster. On the contrary, it's designed to prevent running injuries much like the Nike React Infinity Run 2. 

How does it prevent running injuries?

Soft but responsive cushion: 

  • Contrary to the React Infinity Run 2, the ZoomX foam in the Invincible Run gives a much plusher underfoot feel. 
  • The ZoomX, in comparison to other Nike foams, has more energy return for an improved running economy (runner's energy utilization). 

Stable and smooth ride: 

  • The shoe's combination of wider forefoot nets and rocker geometry creates a surefooted, seamless toe-off. 
  • To generate a locked-in fit, a plastic clip is added around the heel. 
  • Intended for steady steps, the shoe has a wide forefoot to cover a greater surface area. 

What it's for

With the cushioning of the ZoomX Invincible Run, the foot is protected from the pounding on any of these surfaces without completely muting ground feel:  

  • track surfaces
  • road
  • gravel
