Nike ZoomX Invincible Run Flyknit 2 reviews

If you sent me to a desert island and only let me choose one running shoe, I’d take the Nike ZoomX Invincible Run Flyknit 2. Of course, there are lighter running shoes (and probably better designed ones for running on sand), but none of the other best running shoes on the market come close to the spongy, soft comfort offered by this shoe.

When Nike released the first version of this shoe, the Nike ZoomX Invincible Run Flyknit, he positioned it as a shoe for runners training for a marathon, looking for a soft, cushioned shoe for easy race days. After miles of testing, I concluded the shoe was so much more than that – there’s no reason beginners can’t get much out of this shoe. Designed for maximum shock absorption, it’s filled with bouncy, responsive foam that feels spongy and comfortable from your first step. I was nervous about testing the second iteration – how would it compare and would the adjustments have ruined one of the best Nike running shoes on the market? Read my review of the Nike ZoomX Invincible Run Flyknit 2 to learn more.

Nike ZoomX Invincible Run Flyknit 2 review: Price and availability

The Nike ZoomX Invincible Run Flyknit 2 hit the market in the UK in June 2022, so if it follows Nike’s typical launch schedule, it should be available in the US within the next few weeks. The shoe retails for £164.95/$180, which is definitely on the more expensive end of the everyday running shoe market, but the same price as the first version of the shoe. As with the first version, the price is justified as the shoe features Nike’s ZoomX foam, which is the premium foam used in Nike’s faster running shoes (although its focus in this shoe is to be lightweight and responsive in a way that takes some of the offloading from your legs, rather than propelling you to a new PR).

At the time of writing, the shoe is available in three different colorways in the men’s version and four in the women’s version. In men’s shoes, the Invincible 2 comes in red, black, and white, and in women’s, it’s teal, white, black, and sky blue. The Invincible Run 2 only comes in one width, but is by design a wider shoe, so it should work for all runners unless you have particularly wide feet. The shoe is available in sizes US 5 to US 12 in the women’s version and US 6 to US 15 in the men’s shoe.

If you’re on a budget, now’s a good time to pick up the first version of the shoe, as not much has changed and it’s likely to be on sale now.

Nike ZoomX Invincible Run Flyknit 2 review: Design and fit

The Invincible Run 2 follows the design of the original shoe, which has a thick layer of outsole foam that wraps almost around your entire foot like a rubber ring. The shoe has a wide toe box, which was made slightly wider in the second version, which has what looks like a foam onion sticking out from the side. There is also a wide heel, with a centimeter of foam around the heel. Fresh out of the box, it’s extremely comfortable – you sink into this shoe in a way that I’ve never seen with any other running shoe.

The shoe corresponds to the size of Nike. I am a UK 4 in my usual trainers but I was wearing a UK 5 in this shoe. Confused? Discover our guide to buying running shoes and how they should fit here.

The upper of the Invincible Run 2 has been slightly modified from the first version of the shoe. The second iteration has thinner laces, which I found in testing to be more effective at staying tightly laced while running. The first version of the shoe had thicker “rope” laces, while it looks like Nike has returned to the more traditional running shoe lace on the new shoe.

Nike also reduced the amount of padding around the collar of the shoe and changed the tongue slightly. These are small changes – underfoot the shoe felt very much like its predecessor and had the same locked-in feel on easy race days and when I was picking up the pace.

The magic of this shoe is the ZoomX midsole, which is extremely cushioned and smooth underfoot. Unlike many of the best running shoes on the market, there’s no Strobel lining under the shoe’s insole, so your foot rests directly on the ZoomX foam, allowing you to really sink in. in the shoe.

The ZoomX foam is usually reserved for the faster shoes in its collection, like the Nike ZoomX Vaporfly Next% 2and the Nike Alphafly Next%. Both of these faster shoes have carbon fiber plates, and without the plate the foam seems to take on a different meaning in Invincible Run. Instead of propelling the foot forward, the bouncy, responsive foam reduces the impact of every step for a more comfortable ride. The shoe also has the same rocker geometry that we’ve seen in many of Nike’s recent innovations, but again, it’s all about making it easier to run, rather than aiding in quicker starts. Nike says they’ve added more ZoomX foam to the Invincible Run 2, although it’s very similar underfoot.

The plastic rails that wrap around the heel of the shoe are designed to give the shoe extra support. As a runner who tends to overpronate when running with tired legs, I appreciated this.

As I mentioned in the introduction, Nike designed this shoe for marathon runners putting in easy miles on long runs, but the feedback and popularity of the shoe has proven it to be suitable for so much more than that. ZoomX foam is bouncy and responsive, while cushioning your stride, reducing impact on hips, knees and ankles. You probably wouldn’t want to run in this shoe, but there’s no reason you can’t do an easy run and tempo session.

My main issue with the Invincible Run was the outsole – while flexible, the tiny bumps did little to stop me from slipping when running on wet concrete and wore out quickly. Unfortunately, the outsole looks identical to the Invincible Run on the Invincible Run 2.

Nike ZoomX Invincible Run Flyknit 2 review: Performance

Although Nike hasn’t changed much on the surface with the Invincible Run 2, for once I’m happy. It’s a fantastic running shoe that can easily fulfill two roles in your shoe collection: it will keep your legs comfortable and it will help you withstand the pressure of distance training. That said, the ZoomX foam is responsive enough to let you pick up the pace during longer tempo sessions. There’s no reason you can’t run in them, but there are probably better shoes on the market for that.

If you are looking for a super plush shoe for maximum impact protection, you will love this shoe. I stored the first Invincible Run (I have three pairs) in fear that Nike would change shoes, but the different laces aside, they feel nearly identical underfoot, which is great news for shoe fans.

However, the disadvantages are the same as with the first version. The outsole really needs to be more grippy and durable, especially for the cost of the shoe.

Nike ZoomX Invincible Run Flyknit 2 review: Verdict

It’s a great running shoe for beginners and more experienced runners alike. If you’re looking for a cushioned running shoe that will keep you comfortable while running, it doesn’t get any better than this.

If you don’t feel like spending so much on an everyday running shoe, now is a great time to pick up a pair of Nike ZoomX Running Invincible, because the two shoes are very similar, but the older shoe is likely to be on sale. That said, there are other cushioned running shoes at a lower price, including the Brooks Glycerin 20.

While no shoe can keep you from getting hurt, Nike has created a super comfortable running shoe for those days when you run with tired legs. For this reason, I think the Nike ZoomX Invincible Run Flyknit 2 has a place in every runner’s shoe collection.
