Review of the Nike React Infinity Run Flyknit 3

Design and fit

The main changes to the Infinity Run 3 over the 2 can be found in the Flyknit upper, which now uses Nike’s Flywire system to create a more secure fit around the midfoot. There’s also more padding around the heel and ankle, which no doubt contributes to the slight increase in weight: the Infinity 3 weighs 310g in my UK 9 compared to 303g for the 2.

Like its predecessor, the Infinity 3 fits me well in my normal running shoe size and my heel didn’t slip at all. In truth, the upper changes weren’t that noticeable to me during the run, other than the fact that the tongue seems more securely attached with the new shoe – it was easy to tear it off the Infinity’s upper 2.

The midsole feels the same on the new shoe as it did on the Infinity 1 and 2. There’s a generous stack of React cushioning, which has a firm feel that’s softened by the rocker shape of the shoe, helping you to roll smoothly. by your hit. It’s not a “spongy” shoe, which helps with stability – something also helped by the wide base and large plastic heel clip that runs around the rear of the shoe.

Nike did not provide official height and stack offset stats for the Infinity 3, but the 2 had a heel-to-toe drop of 9mm for men and 8.4mm for women. and I assume something similar here.

The outsole has a generous layer of rubber in a speckled pattern and, as with previous versions, I expect it to be able to handle many miles of running. It also grips well on wet pavement.

How I tested this shoe

I ran 50km in the Nike Infinity Run 3 mostly on easy runs with slightly faster effort at a pace just under 4 mins/km. I also logged two hundred miles in the last two versions of the shoe.

The running performance

The Nike Infinity Run has always been a shoe I’ve sought out during intense training times when I want a cushioned yet still stable ride for easy runs on tired legs. The third version is always a great option for this. You don’t get the same peppy squish and bounce from shoes like the Nike Invincible or the Asics Novablast, but the smooth ride is comfortable and reliable, and much more stable even though the Infinity isn’t a total stability running shoe.

You don’t feel the ground in the shoe much, which cushions the impact of running, and it’s not a great option for faster running, which isn’t helped by adding weight in the upper by the Infinity 3. It can handle OK tempo runs, but lacks the speed for interval workouts, which is what you’d expect from a cushioned shoe primarily designed for easy runs.

I didn’t notice the upper changes myself along the way, and if you’re already familiar with the Infinity line, you’ll get more of the same from the 3.

Is the Nike React Infinity Run Flyknit 3 worth it?

The Infinity Run 3 is designed to protect the body while running and help you rack up the miles in comfort without sacrificing stability. He does this job well. It’s not the most versatile or exciting shoe, but beginners looking for a stable neutral shoe or experienced runners looking to complete a spin with a reliable option to log easy runs will find it here.

It’s pricey, though, and you’ll find better value elsewhere. I would start by looking for deals on the Infinity 2 which offers a similar experience and in Nike’s range there is also the Pegasus 39 for £110 which is lighter and more versatile yet comfortable on runs easy.

Outside the Nike range, you’ll find great daily trainers like the Puma Velocity Nitro 2 and Reebok Floatride Energy 4 for £100 or less, and there’s also the Saucony Ride 15 for £130. All three shoes are lighter and more versatile than the Infinity 3, and the Puma in particular has a nicer, bouncy ride, although not as stable as the Nike.
