About
This third iteration of the Nike React Infinity Run fixes the issues of previous versions while retaining the features that made it so successful. This is a shoe with high cushioning that provides a stable run . It can prove to be suitable for pronator runners even if officially it is a neutral shoe (for universal stride).
Notable upgrades to the Nike React Infinity Run Flyknit 3 include a slightly thicker upper and a redesigned heel clip . The whole offers a comfortable and precise foot support.
However, Nike hasn’t changed the sole since the launch of the first Infinity Run in 2020. The running is almost identical to that of the Infinity Run 2 with an added hint of firmness .
All in all, the Infinity Run Flyknit 3 proves to be a smooth training shoe thanks to its pleasant cushioning and its “rocker” geometry which makes it easy to switch from the rear to the front of the foot. It is ideal for easy daily sessions and recovery .
Introduction
Nike originally marketed the Infinity Run collection with a promise to prevent injuries ( 1 ).
The brand claimed at the time that runners would injure themselves less with this model thanks to its good cushioning, wide base, rocker and precise heel lock. This promise was based on an internal Nike study and therefore had to be taken with a grain of salt. However, the formula caught on and the collection has since enjoyed good popularity with runners.
This new version includes all these characteristics with some changes. Can it suit you and should you buy it? This is what we will see in our detailed test.
Cushioning
If you are a fan of the Nike React Infinity Run 2 then you should appreciate this new version because the midsole is almost identical.
We thus find the Nike React foam, which offers sufficient cushioning to hold during a marathon or a half-marathon. The feeling under the foot is balanced, not too soft. Indeed, React offers a good structure and does not compress excessively under load. The only downside is that some testers noticed small creases after several hundred kilometres.
The sole of the Nike React Infinity Run 3 has a sole thickness of 34mm in the heel and 26mm in the forefoot. This gives an 8mm drop.
Testers found there wasn’t much bounce compared to the Nike Pegasus ZoomX but more than the Epic React. In addition, the energy return at the time of toe-off would be insufficient, which makes this model more suitable for training than for racing.
Also, although officially a neutral shoe, the Nike React Infinity Run 3 displays features to stabilize your stride and knee movements. Thus, there is a U-shaped plastic clip that goes from the heel to the middle of the foot to guide your run. It can therefore be a good option for pronators who are looking for a moderate level of correction.
Foot support (upper)
This update features a more comfortable and better-fitting upper than the Infinity Run 2. Nike’s Flyknit mesh is now thicker and more durable. The other side of the coin is that the shoe is warmer and less breathable.
Nike also removed eyelets to allow the mesh to stretch to better lock down the foot. One of the Flywire cables is also missing but the shoe retains a good structure. In addition, the logos on each side are solid and provide lateral and medial support for the foot.
Overall, testers appreciated the fit, which is reminiscent of the comfort of a sock.
The tongue of the previous version had a tendency to tear, so this new model has reinforced stitching to hold it in place. It is more padded and longer, which may not appeal to everyone.
The shoe fits just right and runners with wide feet will be happy to hear that the React Infinity Run 3’s toe box is relatively roomy.
Several runners have also noted that the heel pull tab is gone which makes this running shoe more difficult to put on.
Adhesion and durability
The Nike React Infinity Run Flyknit 3 has the same outsole as its predecessor.
The base is wide for better stability. For its part, the rubber fulfills its role by protecting the platform from abrasion.
Runners have reported running anywhere from 500 to almost 800 km with the previous model and all indications are that this Infinity Run 3 will be able to last that long.
Finally, traction is good even on wet pavement and on less technical trails.
This is paid a little in terms of weight: the shoe weighs 286 grams. But it’s still very reasonable for a training shoe.
Running sensations
The testers are unanimous: the React Infinity Run 3 offers a pleasant and stable run with every step.
The ride is firm and dense with good structure. The sole supports and protects the foot without collapsing under impact. The forefoot is notably stiffer which allows the rocker to work better for faster transitions.
The rebound is not really impressive but there is still a small return of energy to allow you to increase the pace as during uptempo sessions for example.
The cushioning and wide base provide a smoother, more efficient run. And there’s plenty of support and cushioning for longer runs when the legs get tired.
Conclusion
If you’re looking for a well-fitting, cushioned and stable shoe for your long rides and daily training, the Nike React Infinity Run Flyknit 3 is a great option to complete your rotation with its versatility. Its price is a little high but the solidity is there to accumulate the kilometers.
