Nike React Infinity Run Flyknit 2

Nike React Infinity Run Flyknit 2

Nike React Infinity Run Flyknit 2 has just dropped at Running Lab. What did our two wear testers think after running in them? Find out what Keith & Toni had to say here.

The Nike React Infinity Run Flyknit 2 is a fantastic follow-up to V1. Mainly because it seems Nike listened to all of the feedback on what was incorrect on the 1. Lets first start with the addition of the second eyelet at the very top; this is imperative to get a great lock down when it comes to heel slip. Sometimes fashion takes over function and brands do not include the second eyelet at the top. It usually ends up that the next version includes it back in. It should just be a standard in running shoe design. We are glad Nike added this back in as we are already seeing it fit more customers. The second big change was the addition of the foam around the collar. It added to the better heel fit over V1. The bottom of the shoe remains unchanged from V1 with the same react midsole foam which is on the firmer side but bouncy. The heel clip remains in the shoe for that guidance when you need just a little stability to hold your foot in. This shoe dances the line between stability and neutral in the ever growing grey middle ground between the two types of shoes. At Running Lab, we sell this shoe in the neutral category even though we know many that sell it as a mild stability with some great cushion. We think it can fit both. Overall the reviews for this shoe were great and we are glad Nike listened to the changes requested in this shoe from V1. Scroll down to see the testers thoughts!

Keith's take on fit: slightly trim but with compliments.
The toebox is slightly on the narrow side but not so much that it pinches anywhere. The midfoot wraps the foot nicely using a Flywire lacing system and features a very strong arch support. The heel is cupped nicely and the added padding on the ankle collar feels nice. The tongue is mostly attached so there is not much play or ability to adjust. The thinner, stretchier material throughout the laces does however allow a higher volume foot to fit comfortably. The rest of the upper is a more substantial knit that doesn't have much give and can make areas of the shoe feel a bit tight. The upper does handle wet or snowy conditions fairly well. It's not waterproof but it takes a lot to get through. There is a lot of underfoot cushioning to this shoe and the way the forefoot cushioning flares out on both sides of the foot creates a very stable and balanced toe-off experience. The React foam used in the midsole creates plenty of bounce. This shoe runs true to size for me. 

Toni's fit experience: the React will adapt to your foot.

The first impression of the fit was snug in the toe box. I went up a half size from a women's 10.5 to an 11. I do regret going up in size from my running shoe size, the fit became very sloppy after running in them for two weeks. I feel confident that the fit would have adapted if I had stayed with my original size. Additionally, the Nike React midsole cushion is soft, smooth, and responsive. The shoe has a slight rocker style to the midsole that allows for a smooth transition.

Keith: The Nike React Infinity Run is about as stable as can be for a shoe in the neutral category. Thanks to a strong heel counter and extended rails that run up into the midfoot. 

Toni: The Nike React Infinity Run Flyknit 2 is a very stable neutral shoe. There is a lot of guidance in the heel and arch. I usually wear a light neutral arch support but don't have a need for them when I run in the Nike React Infinity Run Flyknit 2.



This one probably isn't going to be for the speed demons. Keith likes it for long runs and recovery runs or any time his feet feel like they need a little extra support. This shoe can handle any distance. Toni personally enjoyed these shoes for her long and recovery runs. The rocking react midsole has an incredible ability to take the to take the stress out of your running.

This shoe fits into the high cushion/high support neutral category. Similar to the Saucony Endorphin Shift, Hoka Clifton, New Balance 1080, Brooks Glycerin. Toni says it's her comfy, make me feel good shoe.

Ask Toni and she'll tell you "OH! Hands down this update crushes last years model!" The changes made to version 2 are major improvements over the original. Nike did a great job improving the fit by slightly detaching the tongue in the Flyknit upper to improve the fit in the heel counter as well as over the instep. A softer, more padded ankle collar and Flywire lacing make the fit much better. In version 1, Keith had to choose between having enough room for his toes and having a good fit in the heel. These changes make both possible. Well worth a little added weight.

Keith: This shoe is for the runner who likes a lot of cushioning and maximal arch support. I would recommend it for someone who wants to do a lot of miles but often end up with their feet feeling a little beat up after their runs. Any runner could use a shoe like this for recovery run days.


Toni: I have dealt with chronic pain in my left foot off and on after my long runs. Usually my Saturdays consist of a long run early in the morning and then limping my way through a 9 hour shift at Running Lab. Since I have been testing the React Infinity Run Flyknit 2, I have been using this shoe as a post long run recovery shoe and it is mind blowing the improvement this proves for my foot pain. This shoe is for anyone that loves cushion and a smooth transition. It can be used for any distance and is definitely worth checking out whether you are training for your first 5k or full marathon. This shoe adapts well.

Running has always been a part of my life. When I was younger it was mainly a way to stay in shape for soccer; running track in the off-season was a way to train hard and stay competitive. I liked it, but it wasn't until my first marathon in my late 20's that I really fell in love with running. Since then I have completed 7 marathons and a 50 mile ultra while also competing in countless 5k, 10k, and half-marathon races. I enjoy running just about anywhere except the treadmill. I prefer trails in the woods to the road and my favorite spot is the Corsair Trail System in the Huron National Forest near East Tawas, MI. I also frequent the many trails we have in Southeast Michigan. I currently work at Running Lab and have worked there for a total of just over 2 years. My favorite thing about running is that it can be super competitive yet the running community is so supportive of each other.

I have been running since 2011 and am in it for the long haul. The longer the event's distance and the more challenging the better. I've been cultivating the running and walking community managing the Running Lab in downtown Brighton since 2015. Running is grownup recess. When your life is lacking joy, go run. When you need to be moved by nature, go run. When you want to celebrate your abilities, go run!

    I've had a pair of these and I work on concrete they are amazing. Lasted me about 8 months before I felt the need to get another pair. I decided to get a custom pair of the Flyknit 2 and it seems they use a different cushion because these aren't nearly as bouyant. Unfortunately, i'll be returning the custom Flyknit 2 and getting the same color I had before. Worth every penny!
