3 Best Nike Flyknit Running Shoes in 2025

With more comfort and cushioning than anyone could want, the Nike InfinityRN 4 also provides the durability needed for an awesome daily trainer. After running countless miles and undergoing numerous lab tests, we crown the Nike InfinityRN 4 as the best Nike Flyknit running shoes.

The Flyknit upper on the InfinityRN 4 is thick and stretchy—very stretchy that it creates a snug fit for our feet providing great comfort. Its tongue, which is 5.6 mm thick, is right in the range of the 5.8 mm average. We loved this comfy upper which gave us pleasant runs day in and day out. 

Comfort also extends to the midsole unit with the new ReactX midsole which is both soft and massive. We measured the heel stack on the InfinityRN4 to be 34.3 mm, which is 1.0 mm more than the average. The midsole is out-of-this-world soft—48.98% softer than the average. Running on marshmallows is an understatement. 

The upper also scored well on our lab's durability tests. We tested the toebox against the Dremel and it came out with an excellent score of  4 / 5. The outsole is 13.28% firmer resulting in only a 0.3 mm damage in our Dremel test (0.9 mm is the average). This shoe can definitely outlast other shoes. 

At 316g (11.15 oz) it is notably heavier than the average of 265g (9.35oz). If weight is a concern, lighter shoes are available.

The Nike ZoomX Vaporfly Next% 3 provides an explosive but plush ride, and has a comfortable and breathable upper, while also bringing traction on dry and wet surfaces. These are more than enough attributes to hail the Nike ZoomX Vaporfly Next% 3 the best Nike Flyknit running shoes for races.

All the magic of the Vaporfly 3 comes from the union of the uber-soft ZoomX midsole and the incredibly stiff carbon fiber Flyplate. It has a thicker stack than its previous version while the carbon plate is moved closer to the ground to provide a more aggressive and propulsive underfoot sensation. True enough, we felt like we could break quite a few PBs with these shoes—from the 5k to the marathon.

The engineered knit material creates a very breathable upper while also holding the foot well. Its weave pattern also has a closer knit along the perimeter of the forefoot for structure and a looser knit around the toe box and midfoot for added breathability. We're not kidding when we say that we had some pretty breeze runs in these shoes.

The Vaporfly 3’s waffle pattern outsole is thinner than previous versions which brings only less weight and increased midsole stack but also a very grippy outsole. It grips well on wet pavement and is quieter and less ‘slappy’ than the outgoing Vaporfly.

Unfortunately, we experienced some heel slippage. While this can be countered by using the extra eyelets and thicker socks, runners who prefer non-slippage can look elsewehere. 

Among Nike’s Flyknit series, Invincible 3 gave us the best shock absorption in our runs with its tall stack and soft cushion combination. It provides comfort and breathability for long miles and offers a consistent ride through its subtle supportive elements.

With a caliper on hand, its stack stands 35.2/25.6 mm, sitting right above the 34.3/25.7 mm average. Our feet are spoiled with supreme comfort as our lab test confirms it's an excellent shock absorber with its high 131 SA score. Plus, it offers an above-average 68.1% energy return, enhancing the whole experience.

We cut the shoe open and found a strobel lining between the midsole and the insole. This layer provides a stabilizing effect that reduces wobbles and ensures safe and sound landings.

A plush tongue hugs the top of our foot for comfort. Upon checking with our caliper, it’s an extra 1.6 mm of cushion vs. the average. Despite this, we could still feel the breeze flow in and out of the upper. Our breathability test confirms it’s more ventilated than the average, with a 4/5 rating.

Unfortunately, this isn't the most agile shoe. Weighing 10.0 oz (284g), this shoe shines best on recovery mileage.
