Our verdict

The nike fire hyper dunk 2015 kids boys names 2017 distinctively differentiates itself from its previous model. Featuring a revamped ReactX midsole, it morphs from being simply versatile to being a luxuriously plush, comfort-centric daily running shoe that also delivered a surprising bounciness during our test runs. Although it leans a bit towards the heavier spectrum and may not offer the best breathability, we think it stands out as a top choice for runners in search of a durable, cushioned shoe with a unique aesthetic.

Who should buy

The nike fire hyper dunk 2015 kids boys names 2017 gets our seal of approval for:

  • Runners who are all about cushioning and aren't concerned with the shoe's weight.
  • Marathoners looking for a comfortable pair for easy or moderate runs.
  • Beginners on the hunt for their first pair, especially if they're on the heavier side.

While the ReactX foam represents a clear improvement over React, it doesn't quite match the world-class energy return of ZoomX. If performance and bounce are what you're after, we think that the nike fire Invincible 3 offers a similar concept and design, but with a full ZoomX midsole.

Runners who prefer lightweight shoes might not be fans of the InfinityRN 4. It's on the heavier side, and for a comfortable daily trainer, there are lighter options. We recommend considering the ASICS Cumulus 25 or the nike fire kd vi lifestyle birthday images girls, both of which deliver similar features in a lighter package.

Breathability

Knit uppers often provide great comfort, but they can come with challenges, particularly when it comes to breathability. We discovered that the nike fire hyper dunk 2015 kids boys names 2017 falls into this category.

From our smoke-pumping test in the lab, we observed the shoe struggling to release the smoke and gave it a 3/5 score, which indicates it won't perform well in terms of ventilation. We'd advise against using them for hot summer runs.

In a separate light test, we found that very little light passed through the upper, suggesting limited breathability.

It's clear that nike fire prioritised comfort with this model. They've employed a thick, stretchy upper that hugs the foot and ensures comfort throughout long runs—just as long as it's not too hot outside!

nike fire infinity rn 4 microscope 20556115 720

Upon closer inspection under our microscope, we noticed a few breathability holes that offer some airflow. Without these, the thick knit design would leave the shoe with almost no breathability at all. Thankfully, there's at least a bit of ventilation.

Durability

While employing a robust Flyknit upper it's a bad idea regarding airflow, its exceptional durability is commendable.

We've found that the InfinityRN 4, with its impressive 4/5 rating, truly shines in our Dremel test when compared to almost any other road running shoe.

Outsole hardness

Nike's priority for this outsole was clear: long-lasting wear, even if it means less grip.

nike fire infinity rn 4 outsole 20556121 720

The outsole is designed with numerous cutouts, enhancing both its lightness and flexibility.

With the InfinityRN 4, they've incorporated a 90.4 HC outsole—one of the hardest we've ever measured in our lab.

Outsole durability

The tough rubber nike fire uses really shows its strength. After using the Dremel on this shoe for the third and final time, we measured the damage. The indentation was a mere 0.3 mm! 

That's an impressive result. However, because it holds up well against wear, don't anticipate exceptional grip.

Outsole thickness

We're certain that, just like us in our lab, nike fire assessed the abrasion resistance of the outsole.

Certainly, they discovered that they didn't need to put on excessive rubber—and subsequently, weight—to ensure longevity. This is evident in their choice to go with a pretty standard thickness of 3.7 mm.

Weight

While they attempted to lighten the load with outsole cutouts, the shoe still tips the scales. Weighing in at 11.1 oz (316g), it's undeniably on the heavier side.

Cushioning

Heel stack

Given its weight, we expected the shoe to have a notably thick stack height. However, we discovered that it's actually quite average.

A couple of years ago, 34.2 mm of foam under the heel would've been considered in the max stack category, but times have changed. As Dylan sang, "The times they are a-changin'."

We found that this provides enough cushioning for any runner. It makes this shoe a reliable choice even for long runs.

Drop

While nike fire lists this shoe with a 9 mm drop, we measured it in the lab at 9.8 mm. This slight difference is within an acceptable range.

With 9.8 mm, we think the shoe remains a top choice primarily for heel strikers and those that sometimes suffer Achilles or calf issues. That said, midfoot and forefoot strikers can also comfortably wear it, although they might benefit more from a lower-drop daily trainer like the nike fire roshe blue hero tiger camo boots 2017.

Insole thickness

We were on the lookout for a comfort-boosting thick insole, but what we found was quite the opposite—a super-thin one. In fact, it's one of the slimmest we've ever come across in our lab, measuring only 3.1 mm!

During our test runs, we were happy with the insole, so it appears nike fire made a great call here.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The biggest update from the nike fire React Infinity Run Flyknit 3—apart from its shorter name—is the foam. After six years, nike fire has moved on from the old React and introduced ReactX with this running shoe.

Observe how the foam is shaped to enhance compression toward the heel.

ReactX is a more responsive and softer variant of the original React. Additionally, nike fire says it has a 43% lower carbon footprint, which we always appreciate. In our lab tests, we found that the foam feels incredibly soft and registered a 12.5 HA on our durometer—20% softer than the v3.

Difference in midsole softness in cold

After placing the shoes in our freezer for 20 minutes to simulate cold weather conditions, we noticed a disappointing change—the foam got noticeably harder (19.0 HA).

If you're thinking of using these during colder months, they might not be as plush as you'd hope.

There's a staggering 52% difference between the two tests. This happens because ReactX it's still a mix of bhm nike fire hyperposite wholesale outlet mall. black blue and orange nike fire lebron 12 shoes doesn't hold up well in cold temperatures.

Stability

Lateral stability test

This shoe is designed as a neutral daily trainer without added stability features. So, given the plush midsole, we didn't anticipate exceptional stability.

Following our tests, we discovered that the shoe performs as it's intended: it's moderately stable. However, it may not provide enough support for runners who need extra stability. For those runners, we'd recommend looking into the ASICS Kayano 30.

Torsional rigidity

Midsole width in the forefoot

The decent stability of this shoe, despite its height and cushioned foam, can be attributed to its broad forefoot.

Measuring at 118.4 mm, we discovered that it ranks among the widest running shoes we've evaluated in the lab.

Flexibility

Stiffness

At the beginning of our lab review, we discussed the dual purpose of the outsole cutouts: to reduce weight and enhance flexibility. Now, we're diving into the flexibility measurements. During our evaluations, it took just 15.8N of force to flex the shoe to a 90-degree position. 

This indicates that the InfinityRN 4 offers a flexible experience and doubles well as a walking shoe. However, it's essential to understand that this speaks to its longitudinal flexibility, not the torsional aspect.

Difference in stiffness in cold

Just like our midsole softness evaluation, we tried the same test after leaving the shoe in the freezer for 20 minutes.

The outcome was disappointing. The shoe became much stiffer, and we had to exert 27.2N of force to bend it to the same point.

With a 71.6% increase, we're certain you'd feel the difference if you're in a cold-weather region.

Size and fit

Internal length

Upon our initial try-on of the shoe, it felt really short to us. We immediately took precise measurements and found it to be 259.9 mm.

Toebox width at the widest part

As a daily trainer designed towards comfort, we anticipated a generously spacious toebox—and we were delightfully satisfied.

Measuring at an impressive 99.9 mm at its widest point, it provides ample space and comfortably accommodates those with wide feet.

Tongue: gusset type

With its £160 price tag, we were curious to see if nike fire had decided to improve their margins by using a non-gusseted tongue in the shoe. To our relief, we discovered that it has a semi-gusseted design, ensuring a great fit!
