Nike ZoomX Invincible 2 vs Nike React Infinity 3 — which running shoe should you buy?

When it comes to finding the best nike running shoes for you, there are plenty of options depending on your preferred style, distance and pace. But if you’re trying to decide between the Nike ZoomX Invincible 2 and the Nike React Infinity Flyknit 3You have come to the right place.

The Nike Invincible 2 and Nike Infinity 3 are everyday running shoes best suited for easy miles, but there are critical differences between them. Both made our list of best running shoes on the market right now, so to help you decide, I’ve scoured the miles in both shoes to help you figure out which shoe best suits your needs.

Nike ZoomX Invincible 2 vs. Nike React Infinity 3: Price and Availability

The Nike Invincible 2 and Nike Infinity 3 released in 2022, updating previous iterations of both shoes – the Nike ZoomX Running Invincible, and the Nike React Infinity 2. The Invincible 2 costs $180 / £164, which is definitely on the more expensive end of the everyday running shoe market, but is 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).

The Nike Infinity 3 is slightly cheaper, costing $160/£145. The shoe is more expensive than the likes of the Nike Pegasus 38 (and Pegasus 39, also released in April 2022), which cost $120.

Nike ZoomX Invincible 2 vs. Nike React Infinity 3: Design and fit

As mentioned above, both shoes are built for easy, everyday miles. They’re both heavier shoes – the Invincible 2 weighing in at 10.10oz (in a men’s US 8) and the Infinity 3 weighing in at 10.3oz. Fit wise, both are pretty true to size – I’m a UK 4 in my everyday trainers and run in a UK 5 in both shoes.

Design-wise, things are quite different between the two shoes. The Invincible 2 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 so that it looks like there is a foam bunion sticking out from the side. It also has a wide heel, surrounded by a centimeter of foam. 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.

As mentioned above, the Invincible 2 uses ZoomX foam, which is usually reserved for Nike’s faster shoes, such as the Nike Air Zoom Alphafly Next% 2 and the Nike ZoomX Vaporfly Next% 2. That said, the purpose of the foam in this shoe is not to propel you forward, but to minimize the impact of your stride for a super comfortable ride on easy race days. The shoe also has a thick, plush upper, with padding around the tongue and collar for added comfort.

The Infinity 3, on the other hand, is much firmer. It uses the same React foam as shoes like the Nike Zoom Pegasus 39, and is similar in its reliability and that “workhorse” feeling. When Nike first released the Infinity, it came with a body of research that looked at how runners run and what they needed from a shoe to prevent common running injuries. The results of the study, conducted by the British Columbia Sports Medicine Research Foundation, revealed that runners wearing the React Infinity had a 52% lower injury rate than the motion control shoe (Nike’s Structure 22), wearers confirming that they felt less pain in their knees and feet. The entire shoe is designed to be structured and supportive underfoot – unlike the Invincible, you don’t bounce around in this shoe.

Like other shoes with Nike’s React foam, I felt like I had to break the shoe – it’s noticeably firmer underfoot, although that’s not necessarily a bad thing. The upper resembles a slipper, wrapping around the foot. It has a wider toe box for a stable underfoot feel, as well as rocker geometry to help support the stride and promote a natural toe-off. This rocker isn’t that over the top, but it’s definitely there.

Nike ZoomX Invincible 2 vs. Nike React Infinity 3: Performance

For two shoes you’d reach for on easy race days, the Invincible 2 and Infinity 3 feel very different underfoot. The Invincible 2 is perhaps as fun as it gets on a recovery run – it’s comfortable, it’s bouncy, and it’s just fun to run. I wore this shoe on days when I didn’t feel like running (anyone who is marathon training will understand) and finished the run feeling energized. I’ve always called it my desert island shoe – sure, there’s probably cooler shoes on the market, or shoes better equipped for the sand, but I love it.

On the other hand, the Infinity 3 is the shoe I should wear for my easy miles – it’s more stable, more controlled and more protective than the Invincible. It’s comfortable enough to wear on your long runs, and it could be responsive enough for faster tempo sessions, although faster runners may find them a bit heavy. And, it’s super durable, so it’ll easily get you through a marathon training cycle.

Nike ZoomX Invincible 2 vs Nike React Infinity 3: Which one to buy?

As for which two shoes you should buy, it entirely depends on the type of running you plan to do. If you’re looking for a shoe that will get you through hundreds of marathon training miles, the Infinity 3 is a reliable and supportive choice. It’s also a bit cheaper, which is definitely worth noting.

That said, if I had the option of both shoes side by side, I would choose the Invincible every time. It’s a truly unique running experience – it’s bouncy, it’s fun and it makes you want to run in it, which is sometimes half the battle. Personally, I couldn’t justify the expense of the Infinity 3 over the Pegasus 39, which is just as durable but much cheaper.

If you’re on a budget, it’s also worth noting that both shoes are very similar to their previous versions. Nike made a few design changes from the original Invincible and the Infinity Run 2, so if you’re looking to save some cash, chances are you’ll be able to pick up an older pair of shoes on sale.
