I’ve been a fan of the React line since the first ones released in 2018. When I heard about the Infinity Runs being released I couldn’t wait to try them out. I tore my Achilles in August 2019 and January 2020 was my first month back getting back to running. So the idea that The React Infinity Run is designed to help reduce injury with more foam and improved upper really appealed to me. I can say that without a doubt the Infinity run delivers on that mission. I ran my first 5K in these since surgery and I don’t feel like I missed a beat. The sole is responsive and comfortable yet still very secure. The extra rubber on the outsole not only provides more grip but leaves the shoe looking cleaner even after many miles. I’m very happy to be able to get back to training ... MoreI’ve been a fan of the React line since the first ones released in 2018.

The Nike React Infinity Flyknit Running Shoes are amazing. Like other Nike Flyknit shoes, the upper is a stretchy, comfortable woven fabric that hugs your feet in just the right way. The soles are supportive. The color and design are beautiful and eye catching. Overall, the comfort and design make these a pair of shoes I will keep reaching for!

The infinity is by far the most comfortable shoe I’ve ever worn. I use them for walking/running and for work wear. The bounce these shoes have is incredible. They help propel you forward. I have had two pairs and I will continue to purchase them. Nike got it right!

Great Shoe. Durable, Comfortable and Fast

I bought the Infinity run after a couple years of running the Nike Epic React and multiple pairs of the Pegasus 36. These Infinity Run's are wayyyy better for a daily trainer. They are more stable. They have more cushioning. They are faster. And probably most importantly, they are more durable. The last pair of Pegasus 36 lasted like 180 miles. I am 50 miles into these shoes and they show no signs or tread wear or breaking down. I bet I get 300 easy on these.So why 4 stars and not 5? I felt like these were slightly too tight in the toe box. The heel cup is really stable but it's very deep. No show socks, even with tabs, will not work. Quarter or crew socks are the only ones that will work with these.

Great running shoe

I've had this shoe for two weeks and ran multiple times. This fits true to size if you don't want heel slippage. I think most people saying they have heel slippage are sizing up to account for foot swelling. If you size appropriately then these fit like a glove. It's not like Nike made the heel of the shoe extra large. They know what they're doing. When I first put it on it felt a little tight but they expand since they're flyknit, which is flexible but secure. After running in them they feel oh so good. The foam feels good and the shape makes it easy to run for a long time. My speed increased by wearing these. I would highly recommend these sneakers for people running out and about or on a treadmill.

Looking to push past the 10k mark? These are perfect.

Favourite Nike Runners so far. I used to wear structure 22s, but these blow them away. Since COVID running has been my therapy. These shoes have been perfect, just enough support to help my pronation and the perfect amount of cushion to allow me to push my running further. I’m at 300 miles on my first pair and they are holding up well. Just ordered a new pair to mix it up. They do have a break in period so give them 15-30 miles to break in. They also run a half size small. Normally I’m an 8, but 8.5 has been working beautifully. Also, they are okay for speed training, but I’m probably going to get a different shoe for faster days. If your looking to start taking your training past 5k/10k distance these are a dream.

React Infinity

5/5. I run 10-20 miles a week when in training. As a casual runner weighing around 190 lbs, I can feel the upgrades to this model and can see why this will be a beloved running shoe. For sizing, they are true to size, 1/2 size up if you're a wide footer. Compared to the Epic React Flyknits 1 & 2, the upper is upgraded to a more durable material than the normal flyknit upper. The newly tooled react midsole and soles is more responsive/durable which is great for your longer/off road(ie. Trackfield, usual flat surfaces) runs. The additional rubber on the soles helps a lot not just in traction but with durablility compared to the react flyknit model. I usually tend have the Pegasus for my go-to model to run with as its a more neutrual/stable shoe for my longer runs. ... More5/5. I run 10-20 miles a week when in training.

With the Infinity Runs, I can definately see these as my go-to when I want a springy bounce in my step for my 5 mile - half marathon runs. Will definately be using these for my training for the upcoming Nike LA 13.1 run on April 5th.

Really good all around.

I genuinely love these. They’ve proven to be extremely comfortable. I have wider feet, but generally regular shoes fit me better than wide shoe because they often widen the toe box but not the middle of the shoe. I have noticed higher end Nike running shoes to be trending more and more towards narrower feet. I found the Next% to be too narrow for me, and also for my wife, who has very average (not wide or flat or any of the other common irregularities) feet. I am so glad that this is a shoe that fits well and remains comfortable through all of my miles. I do have some kind of unusual gait, and often end up with slight runner’s knee, or various other aches and pains after a longer run, beyond standard muscle soreness. I haven’t had any of that so far with this shoe. ... MoreI genuinely love these. They’ve proven to be extremely comfortable.

I have also found them to be reasonably light weight, which is surprising considering the size and comfort of the sole. I have been putting a lot of miles on these desperately trying to find come cons and haven’t been successful. I suspect that these run a little small since I am a full size up from my ususal size, and they seem to fit perfectly.

Solid Training Shoe!!

I am exclusive Nike user when it comes to running so this review is incredibly biased. That being said, I have this in a 4 shoe rotation right now with 2 pairs of Pegasus Turbo 1's and a pair of Turbo 2's. The Turbo 1 is my favorite Nike trainer of all time. The infinity reacts are an awesome addition. I agree with some of the other comments that this is a great recovery day trainer. That's solely what I have been using it for and have done nothing outside with it yet, only treadmill work so far, which is why I gave it an average on durability because I just don't know how it handles outside. Based on the outsole, I would say its a definite improvement over the previous reacts which were not durable at all on the out sole. These reacts are roomier in toe and the ... MoreI am exclusive Nike user when it comes to running so this review is incredibly biased.

Based on the outsole, I would say its a definite improvement over the previous reacts which were not durable at all on the out sole. These reacts are roomier in toe and the flyknit is unbeatable when it comes to comfort. The upper is basically a glove like fit and there is no tongue, its all integrated. The laces have been great and do not come untied unlike some other running shoes Nike has put out, i.e. the Turbo 2's, and the Next%'s. Cushioning is great, although the heel is really squishy if you're a hard core heel striker. The fore foot is wide and incredibly supportive. The mid foot cushioning is a stiffer than the heel and the way the shoe is designed, I feel like it gets me on my toes a little more ( I am a mid foot striker). The white and salmon color looks killer btw. Hope they come out with more colors. I think this shoe could be an all around trainer but I am not there with it yet. I definitely would not race in these but that's also due to the fact that I have Next%'s.

The best keeps getting better

I have ran over one thousand miles the last two years and have worn many different types pf Nike running shoes. Nike keeps making the best even better. I have run in the Free Run Flyknit, the Epic React Flyknit 1, the Rise React Flyknit and now React Infinity Run Flyknit. My immediate impression when first putting on the shoe was how stable the shoe is, it has wider bases at the toes and heels. I also believe the design has a new inner arch support that is noticeable at first but is not noticeable after a few steps. The shoes are extremely well made and light as a feather. Aside from the she looking great, the performance is amazing. The Epic react foam in the souls seems to be the best one i’ve worn yet. Really springy and feels like you are running on clouds.

You can feel an immediate difference when you take the shoes off and switch to a different shoe. If you are looking for a really comfortable shoe that also provides the highest level of performance, these shoes are it!
