Our verdict

The Nike Pegasus 41 GTX delivers real waterproof protection to the iconic daily trainer but comes with a few compromises. We found this Gore-Tex version noticeably heavier at 11.1 oz, £20 pricier, and underperforming on dry roads. However, its exceptional behavior on wet surfaces impressed us—offering excellent grip and enhanced comfort through a well-padded, weather-resistant upper. The ReactX foam and dual Air Zoom units retain the cushioned, responsive feel of the original Peg, making this a solid winter-specific option.

Who should buy

The Pegasus 41 GTX isn’t designed for everyone, but it could be an excellent choice for:

  • Runners seeking a daily trainer that keeps feet warm and dry in rainy or snowy conditions.
  • Those in freezing-cold climates who need reliable grip on wet surfaces and waterproof protection.
  • Fans of the Pegasus series looking for a winter-ready version.

Who should NOT buy

We believe that the Pegasus 41 GTX is not the best option for those seeking a versatile, all-year-round trainer. In our view, its lack of breathability and poor performance on dry surfaces make it unsuitable for regular use outside wet or snowy conditions. If waterproofing isn’t a necessity, we recommend the standard Pegasus 41 or a more versatile door-to-trail option like the Nike Pegasus Trail 5.

Additionally, we think the shoe’s weight is another significant drawback. At 11.1 oz (315g), it’s noticeably heavier than comparable Gore-Tex models like the Hoka Clifton 9 GTX or even the Hoka Challenger 7 GTX.

Cushioning

Heel stack

Starting with the heel, we measured 36.3 mm—slightly higher than the regular model. This is likely due to the thicker outsole and minor manufacturing tolerances, as the variation is minimal.

With such stack height, this shoe borders on the maximalist category for heel strikers, providing ample cushioning for those who land heavily on the heel. Plus, it includes the added benefit of Air Zoom units, which we’ll discuss shortly.

Forefoot stack

We measured the forefoot stack at 24.4 mm using our digital caliper, slightly thicker than the regular edition’s 22.2 mm. Despite this increase, the forefoot remains moderately stacked—still below the average for running shoes, as expected from a Pegasus.

Midsole softness

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

The midsole features Nike's latest ReactX foam, a cutting-edge compound we believe is the brand's finest—ZoomX aside, of course.

The ride delivers a moderately soft feel, and our durometer measured it at 19.5 HA. Bounce-wise, it surpasses the outdated React and vastly outshines EVA-based foams from Nike like Phylon or SR-02.

Additionally, Nike claims—a point we obviously can’t verify but appreciate—that ReactX reduces the carbon footprint by 43% compared to its predecessor.

Midsole softness in cold (%)

Gore-Tex running shoes are widely used in winter conditions, so we tested the foam's performance in freezing temperatures. We placed the Peg 41 GTX in the freezer for 20 minutes and retested it with our Shore A durometer.

The results were underwhelming—it became 37.2% firmer, reaching 26.8 HA, a noticeable difference. However, the Air Zoom units are not affected by cold temperatures, and for this reason, the ride didn't change as drastically as the numbers might suggest. Still, we really hoped for a better outcome in this test.

Air Zoom

The Pegasus 41 GTX also features dual Air Zoom units—one in the forefoot and one in the heel—for enhanced cushioning and energy return.

Rocker

In our view, the Pegasus 41 GTX shines as a fantastic choice for heel strikers, and the well-crafted rocker design we tested only strengthens this conclusion. In fact, v41 boasts the best heel curvature we’ve seen in a Pegasus!

Toebox width - widest part

Nike has been gradually increasing the width in the ball of the foot area over recent years, a trend evident in models like the Vomero 17 and Pegasus 41, and this shoe follows suit as it uses the same MR-10 last.

We measured 102.5 mm at the widest part of the upper, making it noticeably roomy. However, the vertical space feels slightly restrictive due to the thicker Gore-Tex upper, which limits the height more than expected.

Toebox width - big toe

If you're a regular visitor to RunRepeat, you know that analysing the toebox requires more than just one measurement. That’s why we also measured the big toe region to ensure a more complete evaluation.

Nike Pegasus 41 GTX toebox

The second measurement, 74.2 mm, revealed a really tapered, pointy design for this toebox. While the first measurement was roomy, this narrower width in the big toe area creates a snugger fit, potentially uncomfortable for runners with square-shaped feet. Again, this contrast highlights the importance of assessing multiple dimensions.

Stability

Lateral stability test

Right from the start, we found this model to offer noticeably more support than many daily trainers, despite being crafted as a pure neutral shoe.

This enhanced stability comes from the raised midsole sidewalls and the flared heel design—features we highlighted earlier in this lab review when discussing the updated rocker and heel bevel. However, runners with significant stability needs may find it lacking due to its moderate midsole dimensions.

Torsional rigidity

We began our assessment by testing the torsional rigidity of the Pegasus 41 GTX, which scored 3 out of 5. Meanwhile, the non-GTX version got a 2/5.

In our view, this reduction in flexibility is attributed to the updated Storm-Tread outsole and the firmer, weather-resistant upper.

Midsole width - forefoot

While many brands, like ASICS with the Novablast 4, are embracing wider midsoles, we found that Nike stays true to the Pegasus series’ classic design, delivering a traditional daily trainer feel with retained agility.

Using our digital callipers, we measured the forefoot at 113.5 mm—just around what we expected!

Flexibility / Stiffness

With the increased torsional rigidity brought by the new outsole and upper, we anticipated a higher result in this test. Based on our findings, the 23.2N score—compared to the regular Pegasus' 19.2N—was entirely expected.

Despite this slightly elevated outcome, we assure you that the difference is barely perceptible during use. In our view, the shoe retains its smooth longitudinal flexibility, making it an excellent choice for all-day activities and extended walks.

Weight

It’s puzzling that Nike lists the same official weight for both the Gore-Tex and regular models, but we know that’s unrealistic. Gore-Tex is heavier, and the Storm-Tread outsole contributes additional weight too.

On our scale, the shoe registered 11.1 oz (315g), which is 1.2 oz (34g) heavier than the regular edition. While noticeable, we think this increase is justified by the added materials. And it’s a clear reminder that relying on lab tests, rather than brand claims, is essential for accurate data.

Breathability

Gore-Tex is a waterproof membrane designed to repel liquid while allowing water vapour to escape—a solution for keeping your feet dry in wet conditions. However, in our experience lab testing shoes, the ventilation tends to be limited despite Gore-Tex’s claims.

Our light test confirmed this observation, particularly in the toebox, which was heavily blocked. While certain areas in the medial zone allow for a slight amount of airflow, the shoe’s design is clearly more focused on waterproofing than breathability. This makes sense for a winter-oriented shoe anyway.

For further proof, we turned to our microscope, and the results were telling. It was nearly impossible to identify spots where air could escape easily.

While it may not offer top-tier breathability, the exceptional build quality of Gore-Tex products is undeniable—our microscopic photo provides clear evidence of that.

Nike Pegasus 41 GTX mesh

The upper construction of this model closely mirrors that of the Pegasus 41, but with noticeable differences. It features additional padding in the toebox, which enhances warmth and comfort in cold weather, making this variant ideal for winter use.

We also noted that Nike included a rugged toe bumper in this version, setting it apart from the standard Pegasus. Paired with the Storm-Tread outsole, we believe this model can serve as a door-to-trail option.

Durability

Toebox durability

Having a thicker upper with nearly zero ventilation suggested good durability, so we put it to the test using our Dremel like we do in all shoes. This process aims to reveal how well the Gore-Tex layer withstands abrasion.

After testing, we analysed the outcome and rated it 3/5. While slightly underwhelming for a GTX upper, in our view, it still delivers decent resilience. However, the layer closest to the foot proved to be the most durable, offering a reassuring level of protection and longevity for everyday use.

Outsole hardness

Apart from the Gore-Tex upper, the most significant update in the Pegasus 41 GTX is the new Storm-Tread outsole. Using our Shore C durometer, we measured its hardness at 81.4 HC—perfectly average for daily trainers.

Outsole durability

While the outsole excels in wet conditions, it faces a familiar issue—like winter tyres on cars, it wears out rapidly on dry surfaces.

After testing with our Dremel, we discovered a concerning 2.2-mm dent. In our view, this result highlights poor durability on dry terrain. However, considering this is a Gore-Tex shoe intended for wet environments, the outcome feels less alarming than it would in a standard running shoe.

Storm-Tread

Storm-Tread is a new rubber from Nike. Instead of borrowing something from their trail lineup like ATC or partnering with Vibram, they created a material specifically tailored for wet conditions.

Nike Pegasus 41 GTX lugs

We discovered that the Storm-Tread rubber outsole incorporates a cleverly textured pattern with micro-grooves, while the multidirectional shapes effectively channel water away.

However, on dry surfaces, it performs worse than a regular Pegasus—again, similar to how winter tyres from cars function less effectively on dry roads. Nonetheless, what truly stands out from Storm-Tread is the grip, it’s amazing on rainy surfaces or light snow, perfectly aligning with its intended purpose.

Misc

Price

We’d be too naive to expect the Pegasus 41 GTX to match the price of the regular model while incorporating Gore-Tex technology. Most likely, the £20 increase reflects Gore-Tex royalties and materials, and the final price remains reasonable for a waterproof daily trainer.

Tongue padding

We discovered a design update in the tongue of the Pegasus 41 GTX. Nike has added a secondary foam layer, a change that immediately caught our attention during testing. But why the extra material?

Nike Pegasus 41 GTX tongue

In our view, this tweak prioritises water resistance and comfort over weight savings. By incorporating a thicker layer infused with Gore-Tex material, the tongue ensures water stays out effectively.

Through our evaluation, we measured an impressive 10.9 mm thickness—significantly more than the 6.6 mm found in the standard Pegasus 41.

Lacing system

The lacing system in the Gore-Tex edition is nearly identical to the non-GTX version, but this model omits the extra eyelet for tying a runner's knot. This design choice prevents water from leaking into the upper—a required trade-off for weatherproofing.

What really caught our attention were the small, creative details throughout the shoe. The "nike_pegasus-41.gtx" text, styled like a computer file name, is an ultra-geeky detail, and the weather symbols on the lace loops add an extra layer of playful creativity!
