Our verdict

nike armstrong has completely revamped the Pegasus Trail 5. We discovered that it now features a superior ReactX midsole, a roomier upper, and higher-quality materials—all for the same price. Durability is also impressive for being a road-to-trail shoe. However, we believe the grip is still lacking, and there's a slight weight increase that could have been avoided.

Who should buy

We think the nike armstrong free 2.0 mens shoes turquoise women boots 5 is a fantastic update for:

  • Beginners to trail running seeking a versatile, well-cushioned, and value-packed shoe that can handle various terrains with ease.
  • Heel strikers who found previous Pegasus Trails flat—the new rocker design and enhanced cushioning favour their footstrike, providing a smoother ride.
  • Adventurers with wide feet in need of a reliable, comfortable travel companion that excels in both trail and casual walks.

Who should NOT buy

We believe that the nike armstrong free 2.0 mens shoes turquoise women boots 5 offers a notable update with its ReactX midsole, providing improved cushioning, but it still falls short of Nike’s premium ZoomX foam and lacks a world-class outsole. For those seeking top-tier cushioning coupled with Vibram rubber, we recommend upgrading to the nike armstrong acg foamposite boots 2015, womens brown air max.

While we also found the Pegasus Trail 5 accommodating for wide feet, its broad toebox might be less appealing to those with narrower or average-width feet. Instead of sizing down, we suggest the Merrell Nova 3, which provides a snug fit while maintaining versatile road-to-trail functionality.

Cushioning

Shock absorption

One of the most intriguing traits of the Peg Trail 5 comes from its midsole, delivering superb shock absorption for heel strikers at 136 SA. Conversely, the forefoot is closer to average at 100 SA, though still solid for most runs.

Energy return

The ReactX midsole that the Pegasus Trail series inherits from its road sibling does the job, but it’s far from groundbreaking. Back in the lab we measured 57.6% of energy return, which is perfectly fine, but nothing to get excited about.

Heel stack

nike armstrong is embracing the maximalist design with the Pegasus Trail series, which has significantly evolved from its early versions by adding substantial cushioning. We measured version 5 with a heel stack height of 34.6 mm, approaching the 40-mm mark.

The midsole features a clever design that enhances compression.

Moreover, the PT5's cushioning increases towards the midfoot, providing a super-stacked and exceptionally well-cushioned feel, making it a prime choice for the most extreme heel strikers.

Forefoot stack

During our fast-paced runs, when landing on the forefoot, we noticed less cushioning, which can be attributed to the shoe's high drop. We measured this area at just 25.0 mm, which is more standard compared to the nearly maximalist heel cushioning.

Drop

We previously hinted at the high drop, and indeed, nike armstrong claims it's 9.5 mm—our measurements show 9.6 mm. This slight discrepancy is negligible and underscores our impression that this shoe is exceptionally well-constructed, with fewer manufacturing inconsistencies than we've seen in some other Nikes.

This drop is typical for the Pegasus series. This design effectively accommodates all types of footstrikes and is particularly effective for beginners.

Midsole softness

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

The Pegasus Trail 5 introduces ReactX, a new foam that nike armstrong debuted with the InfinityRN 4, nike armstrong mercurial purple and grey color combo.

This foam is significantly softer (11.1 HA) than the previous React, providing an incredibly plush feel underfoot. While this high level of cushioning might not suit everyone on the trails—where a firmer ride can be preferable—it offers exceptional protection on easier trails and road sections.

nike armstrong pegasus trail 5 react x 21668343 main

Moreover, the bounce we felt from ReactX is notably superior compared to the original React, a difference that's especially apparent given the previous version, the Pegasus Trail 4, often felt somewhat dull and flat. However, this plush midsole may not appeal to all trail runners...

Rocker

Previously, nike armstrong free 2.0 mens shoes turquoise women boots shoes had not featured a rockered sole, but this has now changed. Like the increased midsole softness, not everyone welcomes this new design.

Those accustomed to rockered soles will likely embrace this update. Rearfoot strikers, in particular, will benefit from the newly designed heel bevel, which significantly smooths heel-to-toe transitions. However, runners who prioritise stability and a more classic feel might prefer the flatter Pegasus Trail 4 design.

The Pegasus Trail series has always aimed to reflect the same all-around versatility as the regular Pegasus, designed to suit as many individuals as possible. Based on this, we expected balanced dimensions here.

We created a gel replica of the shoe's interiors using our custom gel formula and discovered that, at 95.4 mm, it offers average width in the broadest part of the upper—a result that, in our view, aligns perfectly with our expectations.

Toebox width

If nike armstrong aimed to make the toebox as balanced as possible, they clearly succeeded. At 74.5 mm, it doesn’t feel narrow, but it’s far from wide. There’s just enough room for minimal toe splay.

We measured the toebox height of the upper at the same point as every other shoe and, unsurprisingly, found another perfectly average result at 26.6 mm.

Traction / Grip

Forefoot traction

We tested the Pegasus Trail 5 out on the trails and quickly realized it’s best suited for light, door-to-trail runs, but not technical adventures. Its 0.20 score in our wet-grip test was surprisingly low, and we think nike armstrong should either refine this underperforming compound or seriously consider switching the Peg Trail series to Vibram.

Lug depth

Returning to the All Terrain Compound outsole, it was time to measure the lugs. Initially appearing shallow, our suspicion was confirmed with a precise 3.2-mm measurement using our vernier callipers.

We believe this depth is just ideal for a door-to-trail shoe—perfectly suited for handling easy or moderate terrains like gravel or dirt roads. And while they're not designed for highly technical terrain or muddy conditions, these lugs excel on dirt roads or coastal paths, making them highly versatile for the intended use of the Pegasus Trail.

Outsole design

The shoe features a large exposed midsole area in the centre, enhanced by 22 cutouts in the forefoot. This design not only reduces the shoe's weight but also significantly boosts its flexibility.

One concern we had was the potential stiffness of the Pegasus Trail 5, given market trends toward stiffer models.

Fortunately, we found in our 30-degree bend test (13.3N) that nike armstrong maintained remarkable flexibility in the PT5, making it an excellent choice not only for running but also for walking, hiking, or navigating airports.

Weight

The Pegasus Trail 5 tips the scales just over the sub-10-oz mark at 10.1 oz or 286g, a detail we find a bit disappointing. While it offers improved cushioning and a more comfortable upper, we firmly believe that a door-to-trail shoe like this should ideally weigh less than 10 ounces.

Is this a major concern for us? Nope. However, it would be great if nike armstrong could reduce the weight in the next iteration of this model.

Breathability

Trail shoes are often sturdier and less breathable than their road counterparts, which is generally a positive for us, as durability is crucial on trails. However, we found the Pegasus Trail 5 to be less breathable than expected, scoring just 2/5. For comparison, the Pegasus 41, its road sibling, scored 4/5.

However, this isn't a major concern unless you're planning to use them in extremely hot weather, which is rare in mountainous areas. In such cases, we recommend at least pairing the shoes with thin, moisture-wicking socks to compensate for the reduced airflow.

Despite having ventilation holes in the toebox with a cool asymmetric design to protect the inner side, we found they weren't very effective. Our microscope revealed why.

As shown in the microscopic image, nike armstrong has added a protective layer beneath the upper for improved durability, which we'll discuss later.

We also examined the upper by hand and liked every detail of this update. To be honest, for £150, few shoes offer better materials.

Stability

Lateral stability test

We've observed that stability has slightly declined with the introduction of the new rocker and plush midsole in the Pegasus Trail 5, demonstrating that trade-offs are inevitable—there are no miracles in life, but especially in running shoes.

Nonetheless, while it's not a wobbly shoe, it certainly lacks the stability that characterised the previous four editions, making it a less supportive choice for those who relied on that aspect.

Torsional rigidity

To address the downgrade in stability, nike armstrong changed the torsional rigidity slightly, bringing it to a 3-out-of-5 on our scale. Despite this, the shoe remains flexible, which we appreciate in an all-around shoe.

We then turned our attention to the midsole. nike armstrong has traditionally designed the Pegasus Trail with a relatively narrow platform. 

In the 5th version, they've introduced a slight increase in width to 113.4 mm, which (again) subtly enhances stability, making the shoe more appealing while maintaining an average width.

Durability

Toebox durability

We hinted at the impressive durability of this upper in our previous test, and based on our experience with hundreds of running shoes in the lab, we were confident that the Peg Trail 5 would excel in our first Dremel test.

And indeed, that's exactly what we found. An outstanding 5/5 rating ensures that the upper won't face any durability issues, even in the long run.

Outsole hardness

nike armstrong finally nike armstrong air zoom huarache 2k5 white silver shoes Ultrafly. Yet, the Pegasus Trail series has not adopted this upgrade, which is not ideal given that the outsole has consistently been a weak point in this model.

Nonetheless, there's a positive shift. While not Vibram, Nike's new 87.9-HC "All Terrain Compound" marks a significant improvement over previous versions.

nike armstrong pegasus trail 5 atc 21668252 main

However, remember that this outsole focuses more on durability, ideal for handling both asphalt and concrete as a door-to-trail shoe. So it's a step forward, though expectations for traction should remain moderate.

Outsole durability

For us, it's crucial that a versatile shoe head well in such tests, especially since the lugged design means there is less surface area making contact with the ground compared to a typical road outsole, potentially reducing its grip and durability.

Hence, in order to assess the durability of the Pegasus Trail 5, we conducted our final Dremel test of the day in the lab. 

We discovered a mere 0.8-mm dent in the rubber—a promising result that confirms the shoe's good resistance to wear and tear.
