DISPLAYNike React Infinity Run Review: A Half Marathon Weapon! (1)

That was the first question that came to my mind, so I actively paid attention while running the React Infinity Run and also saw how my legs and feet feel afterwards. The result was interesting, I mean my legs and feet feel good after running, but is that really the effect of the shoes? To be honest, I don't think I'll know for sure until I train really hard for a half marathon on the road. I know from experience that training for half marathons can really take its toll on a high percentage of runners, and for a number of reasons.So why do half marathon runners get so many injuries?

  1. Increasing mileage too quickly without a reasonable baseline weekly mileage.While the half marathon is the logical step for anyone who has run a 5K or 10K before, it's also popular (and to some extent very accessible) for those who haven't run that much, maybe a 5K workout or two Run, you know who you are you crazy coconuts! 🙂 It's a well-known fact that if you increase your mileage too quickly and do too much too soon, you can very easily cause a running-related injury. I've been there, done that and have an ITB injury plus shin splints to prove it. Since then, I've learned how to prevent many running-related injuries by balancing how much I run, running more on trails, and taking turns runningrunning shoes, throw some cross-training into the mix (like biking, hiking, or swimming) and have a solid recovery routine.If you want to learn something from itmy top hacks to increase your mileagethe smart wayRead this article.
  2. For many runners, it's a high-intensity, high-impact distance.The difference between running shorter distances (I classify the half marathon as a shorter distance based on a couple of ultramarathons I've run, it's all relative of course) versus ultramarathons is that it's a distance that tempts so many people (me included), running extremely hard for the entire time it takes to finish. The problem with running at near full intensity for more than 1.5 hours on a street surface is that you are likely going too far and putting a lot of pressure on your legs, which can lead to a variety of injuries including knee injuries, ITB injuries , Shin Splints, Achilles Tendonitis and Plantar Fasciitis to name a few. When I think about it when I look at this list, I suffered from all of these injuries when I started my running journey.

Okay, but how are the React Infinity Run shoes supposed to help and have they tested that?

The secrets of how the Nike React Infinity Run can reduce the risk of running-related injuries are:

  1. Additional cushioning in the React midsole.This gives you a softer landing and reduces stress on your knees, shins and heels.
  2. Widened midsole and outsole in the forefoot area.This provides added stability and reduces lateral roll that can lead to roll ankle. This new shape is very noticeable from above. (the picture below shows what I mean)
  3. curved shape.This curved shape, which you can see in the featured image of this Nike React Infinity Run review, helps runners provide a much smoother foot transition/transition and run.
  4. Lightweight, durable and breathable 3-layer FlyKnit Loft mesh upper.A sturdy upper helps secure your foot, and a comfortable upper means you can run longer without chafing your toes.

Yes, Nike did a test.Nike put the React Infinity Run shoes in the hands (or feet) of 226 runners to see if the shoes could help reduce injuries compared to the Nike Structure 22. The study they commissioned was conducted by the British Columbia Sports Medicine Research Foundation, in which runners followed a 12-week variable training program ending with a half marathon. Based on the results, they believe they are on the right track: In testing*The Nike React Infinity Run showed a 52 percent lower injury ratecompared to the Nike Structure 22.

*ThatNikeReact Infinity Run reduced running injuries by 52% compared to the Nike Air Zoom Structure 22 in a study of 226 men and women during a 12-week running training program (injury = missing 3 or more consecutive runs due to running-related pain). Our study found that 30.3% of Nike Air Zoom Structure 22 runners sustained an injury, but only 14.5% of Nike React Infinity Run runners sustained an injury.

How well do they behave when running?

The React Infinity Run is very comfortable underfoot, even on fast runs, due to the springy and cushioned React foam in the midsole. Nike even added 24 percent more React foam to these shoes compared to the Nike Epic React 2.

They are also very comfortable when changing feet from landing to take off. This is 100% the rocker design that gives me that feeling and I love it. A rocker is nothing new in running shoes, but how Nike has tweaked it for this shoe can give it an improved feel.

The insoles have noticeable arch supportthrough a narrow central part in the lower part of the bodice. This isn't uncomfortable for those (like me) who typically run in a neutral support shoe. It's noticeable though, so if you're absolutely against having arch support, then these shoes might not be for you. Try them yourself and see what you think. Like I said, they didn't bother me.

Overall, the performance of them is very goodand I would definitely lace them up on race day.

Key design features of React Infinity Run

The FlyKnit upper is made from Nike's latest Flyknit technology, Flyknit Loft. It has three layers of breathable mesh that helps maintain its shape while remaining breathable. FlyKnit uppers have historically been less durable than a standard construction, but the 3 layers in this FlyKnit loft make this material much more durable.

The first thing that struck me was how light the upper is, but also how well it hugs my feet, even without the laces. In fact, you could probably run in the React Infinity Run shoes without even using the laces. The top of the lacing system starts much lower than most shoes as they are simply not needed to comfortably secure the shoes to your feet. I love that about them, it's unique and super comfortable that laces don't constrict that region of your feet as they flex so much. You can see what I mean in the wide photo above.

The tongue and rim walls around the opening of the upper are very thin and you might think it will chafe on your ankles and heels, but because the FlyKnit upper is so flexible and soft it feels more like an extra sock, that keeps the shoes on your feet, it's great!


The React foam in the midsole is springy, responsive and has held up very well so far. With 24% more foam in this shoe than the Nike Epic React 2, there's enough cushioning to keep you running in comfort and protection for long.


This outsole offers a lot of grip and while I haven't tried them in the wet, I assume they would hold up well due to the different tread size and deep air pockets which should help reduce the risk of slipping. See below for a closer look at the pattern and structure.

The Nike React Infinity Run has a medium width in the toe area, but narrows towards the midfoot area.

Are they worth buying?

Yes, the Nike React Infinity Run FlyKnit is worth it$160/£140price tag. If you're starting to train for a 10K, half marathon, or even a marathon, and it's a stride that's different than what you're used to running, then these shoes could potentially help you to complete your workout without getting injured along the way. Even when you're not training for a race, the Nike React Infinity Run is so comfortable that running miles feels like a breeze. The upper is comfortable, durable, lightweight and breathable so they are also a great shoe for spring/summer runs when the temperature will be much higher.
