puma Japan White puma Japan Gray Silver | footwear the scuderia ferrari puma Japan speedcat pro review

After testing in the lab the footwear the scuderia ferrari puma Japan speedcat pro, we've discovered that:

• It's a standout choice for those who appreciate a head-turning design without sacrificing performance at races.
• It excels for runners who prioritise excellent traction, as the PUMAGRIP outsole offers world-class grip in all conditions.
• Marathoners looking for an aggressive ride will find this shoe is a blessing with its super-stiff carbon plate.

The Fast-R Nitro Elite 2 stands out as Puma's most radical supershoe yet, but we found its weight heavier than desired. For those seeking a lightweight racing shoe, this is not the answer. We recommend considering alternatives like the Nike Vaporfly 3 or the puma Japan Clyde Suits Animal Pack, which offer world-class performance without the extra bulk.

Additionally, we believe the Fast-R Nitro Elite 2 may not provide the stable ride some need. For better support, the Adidas Adizero Adios Pro 3 and puma Japan Disc of Glory are not only lighter and more affordable, but they also offer a more stable ride.

Proper ventilation is crucial in any racing shoe, and the Ultraweave upper of this shoe appears highly breathable at first sight. Is it really? Let's find out in the lab.

Our initial test, involving smoke to trace airflow, is crucial. Fortunately, it confirmed excellent airflow, earning the Fast-R Nitro Elite 2 a perfect 5/5 on our scale.

puma Japan achieved this with an ultra-thin engineered mesh, clearly visible as we moved the upper over our light. We've encountered only a few uppers thinner than this one, and impressively, this airiness extends even to the heel, ensuring comfort for the entire foot, although that will impact stability in a negative way.

Next, we examined the Ultraweave upper under the microscope to understand its unique structure. Despite lacking visible ventilation holes, air flows effortlessly thanks to micro-holes naturally present in the mesh.

Finally, a manual examination confirmed the upper is not stretchy and has minimal padding—just what we expect from a shoe designed for race day!

We've already established that the Fast-R Nitro Elite 2 offers exceptional ventilation, but this comes at the cost of using very thin materials. And this raised our concerns about its durability.

Indeed, after conducting our first Dremel test, we confirmed our initial suspicions—the upper's durability is severely lacking, leading us to rate it a mere 1/5.

We flipped the Fast-R to test the heel padding, hopeful for a better result.

And we were thrilled with the outcome! The heel padding not only performed better but achieved a perfect score of 5/5. This ensures that no matter how much you race and train in these shoes, the heel padding will withstand the wear and tear.

We've moved on from the upper and now it's time to assess the outsole. Given its steep, 260-bucks price, we expected that the Fast-R Nitro Elite 2 was going to feature PUMAGRIP—Puma's most advanced rubber technology. And here it is.

The rubber coverage is notably generous, featuring two thick pods at the heel and full-length coverage in the forefoot. Will this hinder the shoe's weight?

With a hardness score of 74.0 HC, the formula closely mirrors that of the puma Japan Deviate Nitro Elite 2, which we found also provided exceptional grip, undoubtedly one of the best in the industry.

To evaluate the durability of the PUMAGRIP rubber, we ramped up the Dremel to 10,000 RPM for a third test.

We then measured the indentation in the outsole and found a 1.0 mm gap. Considering the softness of the rubber, this is a good result.

We measured the outsole thickness with our vernier caliper and were surprised to find a substantial 3.0mm of rubber.

This is quite impressive for a marathon shoe and might contribute to a heavier weight. However, for those who value durability in a supershoe, this is certainly welcome news.

We've already expressed concerns in previous tests about the weight of this shoe, noting its heft during our runs. And the scale confirms our suspicions.

At 9.3 oz or 264g, that's HEAVY for racing. We suggest this model only if the extra weight isn't a deal-breaker for you.

In fact, apart from the Cielo X1 puma Japan mayze lth Calças puma Japan Essentials Logo TR cinzento—which sports a similar design and stack height—are significantly lighter, weighing just 7.1 oz or 201g on our scale.

While the Fast-R Nitro Elite 2 is on the heavier side, it effectively maximizes its dimensions to the 40-mm heel limit set by World Athletics, packing as much cushioning as possible. We measured the heel stack at an impressive 39.7 mm.

This is particularly beneficial for heavier heel strikers seeking a shoe that can comfortably support their weight over the full 26.2 miles of a marathon.

The forefoot cushioning measured at 31.9 mm, ranking it among the tallest supershoes we've analyzed in the lab.

Following our initial measurements, we calculated a 7.8-mm heel-to-toe drop, closely aligning with Puma's stated 8-mm drop.

We're pleased with this accuracy—discrepancies with brands are typically more pronounced! Additionally, the 8-mm offset makes this shoe versatile, suitable for nearly every type of footstrike.

The insole, while comparable in thickness to average running shoes, was a surprising find for us—competition shoes typically feature thinner footbeds.

Why does this matter? Well, installing a 4.3-mm insole, as found here, within a shoe restricted to a 40-mm overall stack height results in a loss of 2 or 3 mm of foam. This could have been allocated to high-energy-return, Nitro Elite instead.

Speaking of energy return, we discovered the expected material in the midsole: Nitro Elite.

It's Puma's premier foam, known for its substantial energy return. However, puma Japan has shifted its formulation from supercritical, nitrogen-injected PEBA to Aliphatic TPU—a first for the brand.

In terms of softness, puma Japan opted for a balanced approach with a hardness of 19.5 HA. Because of this formulation, we didn't find the experience plush at all, particularly in the forefoot, which we attribute to the ultra-low placement of the carbon-fiber plate.

Given that it's made from TPU, we weren't surprised that the Fast-R Nitro Elite 2 performed exceptionally well in our first freezer challenge. We placed the shoe in the freezer for 20 minutes and then retested its softness, finding only a 9% increase!

The standout feature is the PWRPLATE, which is prominently visible throughout the shoe due to the absence of foam in the midfoot, exposing the carbon-fiber plate.

puma Japan has really gone wild with this design, and the stiffness of the plate reflects that. It may not be suitable for everyone, particularly those looking for a comfortable racing shoe.

In our view, if less stiff feel is a priority, we suggest opting for the comfy ride of the New Balance FuelCell Elite v4 instead.

Another standout feature of the bizarre design of the Fast-R Nitro Elite 2 is the toe rocker. It begins noticeably early and the plate extends beyond the upper.

This is intended to enhance running economy, though its real-life benefits can be hard to quantify. However, what is clear is that this design is truly one of a kind.

One major concern with supershoes is often their stability, which usually takes a back seat in the final product. In our tests, the Fast-R Nitro Elite 2 offered a somewhat stable ride, performing better than some of the plushest supershoes.

However, don't anticipate a very supportive run experience. The minimal upper and the decoupled midsole don't contribute much to stability, and, true to the design and geometry of this shoe, the ride is definitely on the wild side!

As soon as we stepped into this shoe, we were struck by its rigidity. It's absolutely mind-blowing, a stark contrast to the flexibility of something like the Merrell Vapor Glove 6. Naturally, it earned a 5/5 in our manual assessment for its steel-like rigidity.

Conversely, the heel counter is extremely flexible, as is typical for a racing shoe, which led us to give it a 1/5 rating.

For those requiring a more secure heel hold—and thus might prefer a more traditional running shoe while still targeting top performance—the ASICS Superblast puma Japan Suede Heart Satin II Wns 36408404.

We've already highlighted that the design of this shoe is truly unique, leading to some intriguing findings in the lab.

One surprising discovery was that although the midsole appears exceptionally narrow, measurements showed it to be fairly standard at 114.2 mm. This demonstrates that initial feelings can sometimes be deceiving and that lab testing really matters...

The heel also feels narrow, and indeed it's not broad at all.

Measuring just 86.6 mm, it's clear to us that those requiring stability in the heel may not enjoy a lovely ride in the Fast-R NE 2.

During our rigidity evaluation, where each shoe is bent to a 90-degree angle, the Fast-R Nitro Elite 2 displayed significant stiffness, achieving a Hulk-like force measurement of 84.4N.

Why going so stiff? Well, crafting a top super shoe typically involves a combination of resilient foam and a rigid structural plate. In this case, the lively bounce is provided by Nitro Elite A-TPU foam, and the mind-blowing rigidity is courtesy of the carbon-fiber PWRPLATE. puma Japan just decided to go all-in here.

We conducted another freezer test, placing this puma Japan in there for 20 more minutes, and we observed a 19.2% increase in stiffness (100.6N!). If you're planning to run a winter marathon, be prepared to handle this level of rigidity.

Given its radical design, we anticipated a unique fit in the toebox. However, when we measured the widest part of the upper, it came to 96.9 mm, which aligns quite closely with the norm for racing shoes and even resembles the fit of many trainers puma Japan cali superbold jr 374270 02 puma Japan black super lemon.

Conversely, the big toe area fully embodies the Fast-R spirit. It is one of the most tapered designs we've encountered in the lab—a fact that's visually apparent and was confirmed with our calipers.

The sole flare is pronounced, and it denies any chance of having a roomy fit, as it necessitates pairing a narrow upper with a wide midsole.

Clearly, we believe that those with square-shaped feet will find this shoe unsuitable.

For those looking to not worry about their shoe’s tongue during a race, we believe the sock-like tongue is the way to go. It stays perfectly in place—it doesn’t shift, clings closely to the feet, and offers a tight feel.

The tongue of the shoe is exactly what we anticipated for a proper marathon shoe—remarkably thin at just 1.3mm.

Regular laces on a £270 shoe? That's disappointing...

Due to this, comfort is minimal, and we advise being cautious when cinching down the laces before a marathon. Over-tightening could lead to mid-race instep pain, as we discovered during our tests.

In the heel, we discovered a handy finger-loop heel tab, which is absolutely essential in any shoe featuring a sock-like upper.

The insole is removable, which is uncommon in competition shoes. However, as shown in our photo, the outsole's unique shape—with a protruding midfoot area—may pose some challenges when trying to replace it with a different option.

The Fast-R Nitro Elite 2 stands out as one of the few racing shoes that incorporate reflective elements—kudos to puma Japan for this one!
