Our verdict

If you're looking to break from the mainstream, the tenis puma nrgy comet azul branco could be your go-to stability daily trainer. We found that it combines responsive foam, fantastic traction, and superb stability—a trio that's hard to find, all enriched with unique features that set it apart from the competition. Nonetheless, we hold some concerns regarding the outsole's durability and tight forefoot. Moreover, the 10-mm drop might not appeal to every runner out there.

Who should buy

After testing the ForeverRun Nitro both in the lab and on runs, we believe it’s an excellent choice if you:

  • Prefer a well-cushioned and stable daily trainer that feels surprisingly light for its size.
  • Trainers PUMA X-Ray Ac Ps 372921 08 Blue White Peacoat Green.
  • Don’t wear out outsoles quickly and prefer a high-drop option for daily training, including long runs.

Who should NOT buy

The ForeverRun Nitro from PUMA presents a 10-mm drop that might not appeal to everyone—forefoot strikers, in particular, might find it less than ideal. If this is a concern for you, we suggest exploring alternatives like the Hoka Arahi 7 or the puma al always ready bra, Kudottu PUMA nro 1 logomerkki takana.

Additionally, we've noted that runners who typically see wear in the interior medial part of the midfoot might find the ForeverRun Nitro's outsole problematic. For those encountering this issue often, we recommend the ASICS Gel Kayano 31. Puma Pantalones Cortos Train Embossed 9 Bike.

Cushioning

Heel stack

The heel of this shoe, measuring at 36.1 mm with our calipers, offers substantial cushioning but doesn't reach the heights of a true maximalist shoe.

While it may not seem as groundbreaking compared to earlier years or next to giants like the ASICS Superblast 2, Puma LIGA Base Layer T Shirt Junior Boys.

Drop

PUMA claims that this shoe features a 10-mm offset, and our measurements in the lab confirmed precisely that difference between the heel and the forefoot. This accuracy is a rare instance where the brand hit the mark perfectly!

The 10-mm drop is often viewed as a versatile choice for a daily running shoe, appealing especially to heel strikers, yet versatile enough for various types of runners. And we think it's a good solution for this shoe.

Sunblaze Puma Black | Midsole softness

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

One distinct advantage of PUMA training shoes over others is the Nitro midsole, which uses nitrogen-infused foam, typically outperforming most training compounds from other brands.

In the ForeverRun Nitro, we discovered a well-balanced foam that isn’t overly plush, a strategic choice for a shoe designed with stability in mind. While softer foams may be tempting, they could lead to an unstable ride.

This was expected because Nitro, unlike plain EVA foam, doesn't lose its softness excessively under cold temperatures.

The fit isn't particularly roomy, but it isn't excessively narrow either.

Our initial measurement at the widest part of the upper showed 97.9 mm—just about average. This felt typical to us during our runs too. However, the shoe’s low-volume upper makes it less suitable for those with larger feet, as demonstrated in the video above.

Stability

Lateral stability test

The ForeverRun Nitro is marketed as a stability shoe, and we agree—it really hits the mark, checking most boxes for modern, non-intrusive stability trainers and even going a step further.

tenis puma nrgy comet azul branco RunGuide

We discovered that PUMA employs Nitro they call the RunGuide System, which is essentially a cool way of saying it's a stable shoe without medial posts or other intrusive elements. They achieve this using techniques like the PWRTAPE reinforcements, a hard plastic heel counter and a massive sole flare, which centers the feet and provides an incredibly wide landing base.

Torsional rigidity

We were surprised to discover that from a torsional standpoint, the ForeverRun Nitro is not very stiff, rating only a 3 out of 5, which is less common in stability shoes. This might explain why it felt to us like a daily trainer in terms of comfort, yet still offered excellent stability.

If the previous test surprised us, the second left us truly puzzled. It's quite unusual for us to encounter such a flexible heel counter in a supportive shoe. This 2/5 result clearly indicates that PUMA is intent on doing things differently, diverging from the design approaches of most other brands.

For this reason, this shoe is ideal for runners with sensitive Achilles tendons or those dealing with Haglund's deformity, thanks to its plush and flexible heel area.

The enormous dimensions of the ForeverRun Nitro's midsole stand out, particularly with its forefoot measuring a substantial 121.1 mm.

This result is typical in stability shoes and contributes significantly to the shoe's performance. We observed during our runs that the massive size provided a stable landing pad for us, enhancing confidence with each stride and throughout the transition to toe-off.

Midsole width - heel

The ForeverRun Nitro sets itself apart from most modern stability shoes because of its narrow midfoot area. Unlike others, like the PUMA Trc Blaze Triple 384959-02, which maintain a broad shape throughout, the FRN narrows significantly at the midfoot before the heel expands again, reaching a super wide 101.8 mm in the heel area.

Flexibility / Stiffness

We've noted throughout this review that the ForeverRun Nitro often feels more like a neutral daily trainer than a traditional stability shoe, and our findings from the longitudinal stiffness test support this impression.

The shoe yielded a low stiffness result of 22.6N in our 90-degree bend test, reinforcing its suitability for those seeking a comfortable trainer that also serves well for other activities.

Weight

The ForeverRun Nitro may look like a very large shoe and initially gives off a heavy-duty impression.

However, once we placed it on our scale and took it for a run, it proved to be surprisingly lighter than it appears. Weighing in at just 9.7 oz or 274g, PUMA has impressively managed to shave significant weight off this model, keeping it below the 10-oz benchmark!

Breathability

One thing we honestly appreciate about PUMA—and this review will highlight this frequently—is their disregard for conventional trends, crafting shoes that truly stand out. The ForeverRun Nitro's mesh upper, with its unique design, exemplifies this approach.

Concerned about how the comfort-oriented, padded minipods in the forefoot might affect breathability, we initiated our testing with the smoke machine. We were pleased to discover a rating of 4/5!

Illuminating the upper revealed the detailed mesh minipods and the supporting PWRTAPE reinforcements more clearly. But rest assured, these features did not hinder heat and moisture evacuation enough.

tenis puma nrgy comet azul branco microscope

PUMA has cleverly spaced the pods to ensure adequate air stagnation, a fact we confirmed under our microscope. It's impressive to witness such precision in manufacturing.

tenis puma nrgy comet azul branco microscope 2

The upper of this PUMA is intentionally crafted without extensive cushioning. This suggests a focus on weight reduction, potentially catering to users who prioritize lightweight, thinner uppers.

Another nice feature of this shoe is the perforated PWRTAPE reinforcements on the upper. These enhancements ensure breathability without sacrificing support, and we absolutely love it.

Durability

In theory, the tufted pods on the ForeverRun Nitro should also enhance its durability. To test this, we fired up our Dremel, ready to destroy yet another upper here in the lab!

The initial results were quite promising. While a 3/5 may not seem spectacular, it's definitely a positive outcome for any road running shoe. This further confirms that PUMA's unique design not only looks good but will endure over time.

Heel padding durability

Unfortunately, the heel padding was a disappointment, and we also noticed some minor heel slippage—this could become a significant concern for many runners. We recommend wearing your most cushioned, high-grip socks to mitigate this issue.

We also discovered that the Dremel inflicted more damage than anticipated, leading us to rate it a disappointing 2/5—a score that might raise some eyebrows.

Outsole hardness

The stakes were high for the outsole because, in recent years, PUMAGRIP has secured its reputation as one of the top-tier rubber compounds in the market, alongside heavy-hitters like Vibram and Continental.

tenis puma nrgy comet azul branco lugs

And indeed, the outsole did not disappoint when it came to grip—it was exceptionally effective in both dry and wet conditions, providing robust traction across various surfaces, reminiscent of our experiences with other PUMA PUMA Carina Leather Women's Sneakers in White Silver Deviate Nitro 3.

tenis puma nrgy comet azul branco outsole coverage
Rubber coverage is impressive compared to other shoes, though the ample exposed foam on the inner medial side is unusual for a stability shoe.

The outsole design appears to be highly engineered, perhaps to the point of being overly complex. It blends small voids with mini-lugs that seem inspired by a puma's fingerprint and come in various shapes. Additionally, the brand's logo adorns the heel.

Finally, were also surprised to find the rey reading slightly lower than anticipated at 75.3 HC, which might impact its durability.

Outsole durability

While the outsole clings like puma claws, its durability falls short.

Misc

Reflective elements

Not many daily trainers feature reflective elements, but we discovered that the ForeverRun Nitro includes a few. They aren't the most eye-catching we've tested, yet they still provide some added safety for you.

Tongue padding

The tongue in this shoe strikes a perfect balance between comfort and weight. PUMA took a clever approach, as they added just a 5.3 mm pad to protect the instep, while keeping the rest of the tongue thin and streamlined, which significantly cuts down on weight.

tenis puma nrgy comet azul branco dual tongue loop
The lacing system excels with a PWRTAPE reinforcement at the first eyelet, improving support. It also features a rare dual tongue loop.

This design doesn't offer the plush comfort of pillow-like tongues, but it's a trade-off that pays off by saving weight and still providing sufficient protection. We think it's a smart choice if you're looking for a more dynamic shoe.

The tongue is semi-gusseted, meaning it's partially attached to the sides—our preferred setup for daily trainers. We're happy to see that PUMA didn't skimp on quality here, especially since it's common for some brands to cut corners on this often-overlooked feature to save a few cents per shoe.

Removable insole

The insole is not made by PUMA but by the Danish company Kaiser Sport & Ortopædi. Although it's replaceable, doing so means losing one of the shoe’s unique features—the small built-in metatarsal pad.
