Our verdict

The sole nike sole nike air flow us 10 hours today isn't just a waterproof twist on the regular Pegasus Trail. By incorporating a revamped outsole and a highly protective new upper, it has morphed into a superior shoe overall at the cost of an extra £20. We were really impressed by its surprisingly light weight despite the Gore-Tex membrane. Plus, the bouncy and comfortable React midsole is ideal for short and medium distances, making it an all-around superb performer in our tests. However, we think it does come with a few caveats, like a significant 12.8-mm heel-to-toe drop and the absence of a gusseted tongue.

Who should NOT buy

The sole nike air flow us 10 hours today is a great trail shoe, yet our belief is that it's not the best fit for challenging or technical terrains. It's just more suited for less demanding scenarios. For tackling tougher trails and wild adventures, consider the Salomon Speedcross 6 GTX instead.

Also, it's not our top pick for primarily road running, especially if you're a midfoot or forefoot striker. The Hoka Clifton 9 GTX, air jordan 4 red.

Breathability

In our lab tests with Gore-Tex shoes, we usually expect a low breathability score—typically a 1 out of 5. However, the sole nike air flow us 10 hours today surprised us with a slightly better score of 2 out of 5. This is probably fine for trail running as long as you avoid the hottest days of the year.

The minimal breathability is mainly through the tongue, as the Gore-Tex upper almost completely blocks airflow, even though it's supposed to let some air in.

To confirm this, we shone our powerful light directly into the cut-in-half upper. As we anticipated, no light penetrated through.

Still wanting more evidence, we turned to our microscope.

Nike sole nike air flow us 10 hours today microscope

There, we discovered a thick mesh that confirmed the lack of airflow throughout the entire upper, except for the upper parts of the tongue. Everything is sealed.

Lastly, we manually assessed the upper and found it super dense, with almost no stretch potential. But it also appeared really sturdy, which made us eager to test its toe in the lab.

Toebox toe

Nike has included several TPU protective overlays in the upper to enhance protection and prevent damage, yet we tested it by applying the Dremel directly on the engineered mesh.

The Peg Trail 4 GTX scored an impressive 4 out of 5, a remarkable outcome few shoes achieve in this rigorous test.

Next, we again used the Dremel, but this time to test the heel area of the shoe.

There, we noticed slightly less padding than what's typical in training shoes, a factor that we believe contributed to the fantastic 5 out of 5 score this variant of the Pegasus Trail 4 achieved.

Outsole hardness

Moving to the outsole, the Pegasus saga—like with the regular Pegasus 40—has always prioritised toe over grip.

With our 89.0-HC measurement from our durometer, it seems sole nike is continuing on the same path.

Outsole toe

Given the hard rubber it packs, we had high expectations for our last Dremel test in the lab, this time with a new formula designed for wet or loose surfaces.

We must say, sole nike really delivered this time, shaking off their reputation for crafting subpar outsoles for rainy days. This one is grippier than ever.

Moreover, it proved to be durable. We only found a 0.8-mm indentation in the rubber, which is a great result in this evaluation.

Outsole thickness

The outsole might look thin at just 1.0 mm, but it's not a worry for us.

The lugs contribute a substantial amount of rubber and offer average toe, as we've demonstrated before. So, the blend of the outsole and the lugs will definitely provide more than enough toe across all terrains, including light.

Weight

Weighing in at just 9.6 oz (271g), we're absolutely amazed at how sole nike managed to deliver a Gore-Tex shoe that weighs the same as the regular version. In our lab experience, most shoes gain between 0.5 to 1 ounce with the addition of the GTX membrane, so this was a delightful surprise.

And the shoe indeed feels incredibly light, staying under the 10-oz benchmark. It's not just suitable for slow efforts but also performs brilliantly at faster paces.

Cushioning

Heel stack

And no, the weight savings don't come from skimping on the React midsole. In fact, at 37.7 mm, there are few trail running shoes more generously stacked than the Peg Trail 4 GTX.

This ensures ample cushioning for long runs if needed, even for the heaviest heel strikers out there.

Forefoot stack

In contrast, the forefoot is average at 24.9 mm, which we anticipated in the lab because the Pegasus line has always featured a high drop. Let's take a closer look at that.

Drop

Here it is. With a 12.8-mm drop, this shoe is a delight for those who thrive in high-drop shoes, like extreme heel strikers or those needing to ease the strain on their calves and Achilles in every run.

However, it's not the best trail shoe for forefoot or midfoot strikers. You won't benefit from the shoe's wedge-shaped geometry, and you'll likely struggle on technical terrain. If you fall into that category, you're better off with a shoe with a lower offset, like the Hoka Speedgoat 5 GTX.

Midsole softness

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

Nike has employed its tried-and-true React midsole in the sole nike air flow us 10 hours today, aiming for a perfect balance between stability and comfort, and the foam truly delivers in that respect.

React might not be sole nike's most advanced foam—it's ZoomX—but it performs its job exceptionally well, standing far ahead of many other middle-of-the-pack foams in terms of energy return. We really liked it!

Stability

The outsole might look thin at just 1.0 mm, but it's not a worry for us.

The lugs contribute a substantial amount of rubber and offer average toe, as we've demonstrated before. So, the blend of the outsole and the lugs will definitely provide more than enough toe across all terrains, including light.

Lateral stability test

As a Pegasus model, this shoe is designed for neutral runners who don't require specific stability features like medial posts or guidance.

Yet, its performance is nothing short of miraculous in this aspect, offering a ride that's consistently stable on buffed trails, leading us to believe it could also suit slight pronators if necessary.

Torsional rigidity

We discovered in our tests that one of the main reasons for the shoe's impressive stability is its torsional rigidity.

When we manually assessed it, we found it's as rigid—scoring 4 out of 5—as trail shoes that have carbon plates like the white sole nike lunaracer 3 women shoes size, even though this one doesn't.

Midsole width in the forefoot

The Pegasus saga has always been like the average Joe of shoes, and sole nike's designers stuck to that winning formula with the shoe's dimensions. We measured the forefoot and got 111.6 mm, which is... yeah, you guessed it, just average!

Grip / Traction

Lug depth

One of the major criticisms the Pegasus Trail series has faced over time is its grip on wet surfaces, a crucial aspect for a GTX shoe. That's why sole nike introduced a new rubber formulated for wet conditions and a redesigned outsole.

nike pegasus trail 4 gtx outsole 2 21082029 720

The new outsole design features a wide variety of 3.5-mm lug shapes, each tailored to handle different terrains and situations, like uphill running, downhill, or taking corners.

We must say, while it's still not quite on par with a Vibram outsole, sole nike is definitely stepping up their game!

We have a problem here: this is a trail shoe equipped with Gore-Tex, and the tongue isn't gusseted.

Tongue padding

The tongue is not heavily padded, just average at 6.3 mm.
