The Nike React Infinity Run Flyknit 2 features the highest amount of React foam cushioning among running shoes. Its midsole is thicker than the React Miler’s, but it weighs less than both the Miler and the ZoomX. While it may not be ideal for speedy runners, it offers a comfortable ride for those looking to increase their pace.
Upon wearing the React Infinity 2 initially, you’ll notice substantial ground protection. Nike’s research shows that the React Infinity 2 outperforms the Air Zoom Structure 22 (Nike’s motion control shoe) by 52% in injury prevention. This shoe is among Nike’s most extensively tested models.
The React foam offers a softer and higher-quality feel compared to Cushlon foam, providing better support and stability. Long runs no longer result in knee and hip discomfort, as with my Winflo shoes. The improved energy return touted by Nike is noticeable in this footwear. Despite the increased stack height, the shoe maintains good ground feedback.
The React Infinity 2 features a heel-to-toe drop of 8.4 to 9 mm and incorporates a rocker geometry for seamless transitions. Running in these shoes feels significantly smoother compared to the Winflo, despite the Winflo being $60 less expensive.
I don’t want to return to using the Winflo for my daily runs after trying the React Infinity 2. The Winflos seem to offer better support around the heel and are more comfortable for walking on pavement. Additionally, the React Infinity 2 has a more athletic appearance compared to a casual look.
Wide-footed runners will find sufficient space in the toe box. The React cushioning in the forefoot is excellent. However, individuals with extra-wide feet might need to adapt to the extended heel clip that influences the midfoot width. While I appreciate the support from the plastic/rubber clip, some runners have reported a poking sensation in the arch.
The heel clip secures the ankle during running to prevent unnecessary foot movements. It functions akin to the Brooks GuideRails, offering excellent support for my somewhat flat feet. Even on long runs, I didn’t encounter knee or hip discomfort, indicating effective cushioning and alignment of the feet. However, this shoe might be most suitable for neutral runners and supinators, as I desire more arch support.
The shoe performs better on pavement than on the track. Adding a Zoom Air unit to the forefoot would enhance its performance. The React Infinity 2 features a broad base for increased stability, even without tightly tying the laces. The React patterns on the outsole offer added comfort during your run.
The additional rubber on the outsole enhances traction on wet pavement. Certain runners prefer the React Infinity 2’s grip over the Peg 38, while the React Miler offers slightly superior traction. However, there is a desire for the outsole of this shoe to provide more safeguarding for the midsole foam below the midfoot.
The Flyknit upper offers a more comfortable feel compared to the ZoomX. It boasts excellent breathability and features sturdy Flywire cables that deliver lightweight support and stability no matter how your foot strikes the ground. These cables are linked to the lacing system to ensure a secure fit. It’s advisable to wear socks with the Flyknits as the lack of a soft lining, particularly in the forefoot area, may not be ideal for some individuals.
The React Infinity 2 is ideal for casual runs and can also be suitable for seasoned runners tackling longer distances. It adapts well to increased speeds, offering remarkable cushioning and impact protection. However, it may not provide the same agility as a shoe featuring a Zoom Air unit in the front foot.
Nevertheless, there was a flaw that I identified in the upper design: the short and fragile tongue. While the tongue provides great comfort beneath the laces and functions adequately, its brevity makes it challenging to grasp easily. Initially, when I wore the shoe for the first time, I refrained from adjusting the tongue due to concerns about potential damage.
The Flyknit upper’s tongue can get stuck, leading some runners to pull it too hard and rip the middle. If the tongue were a regular length, there would be no need to tug it for adjustment.
Final Thoughts
The Nike React Infinity Run Flyknit 2 is a top choice for safety-conscious runners. It features ample React foam cushioning, proven to be 52% more effective at preventing injuries than the Air Zoom Structure 22. The React foam provides superior energy return and durable cushioning. Additionally, its breathable Flyknit upper is ideal for warm conditions.
