After the FuelCell TC— New Balance's first shoe to show off a carbon plate—here's the FuelCell RC Elite, a shoe whose keywords are comfort and versatility.

It comes with a high-stack cushioning with a height of 35 mm under the heel and 25 mm under the forefoot. The FuelCell foam gives a soft and plush cushioning with a firm touch under the heel. The soft feel of the sole is very similar to that of the Adidas Adios Pro. The result is a very comfortable ride, but the testers judged the bounce to be moderate. The carbon plate—discreet under the foot—does its job and provides a responsive ride with fast transitions but maybe not as impressive as on other similar models (like the Nike AlphaFly, to name only one). Therefore, the ride is actually close to what you get from a traditional running shoe, making it an exciting option for runners looking for a more accessible, more comfortable carbon plated shoe.

Next, the mesh of the upper is soft and relatively thick for a racing shoe, which reinforces the overall feeling of comfort. The shoe fits true to size, but the lockdown is a little loose in the middle of the foot, according to several runners. It's one of the main issues of this model: runners are concerned that it may not be secure enough for racing. The toe box offers enough room, and the heel counter perfectly locks-in the foot. The design is very nice with a sleek build and bright neon colors, although, of course, it's a matter of preference.

Finally, the Dynaride outsole and its small triangular rubber lugs give good traction and seem durable: testers didn't notice any signs of wear after several runs. Besides, the lugs also equip the tip of the shoe to act as a toe bumper that protects the toes and makes the shoe more sturdy.

To summarize, the FuelCell TC is a great carbon plate running shoe with a soft and flexible platform that received high praise from many seasoned runners. Its combination of performance and comfort make it a very versatile shoe. Make no mistake though: it's a shoe built for marathon racing, but it's also suitable for daily training.

Adidas is making a big splash for the start of the Autumn season with the Adidas Adizero Adios Pro, its second shoe to use a carbon plate. Like its direct competitors (such as the Nike Alphafly or the Brooks Hyperion Elite 2), the Adios Pro features a very high-stack cushioning to run comfortably long and fast.

When we mentioned that the Adios Pro featured a carbon plate, we only told half of the story (or even less). Indeed, the shoe has not one but six plates! First, there's a carbon-infused nylon plate under the heel to improve stability and compensate for the narrow profile of the rearfoot. Second, there are five "EnergyRods" made of carbon-infused TPU that support the toes to promote smooth transitions and a springy ride. These propulsion plates are surrounded by the new Lightstrike Pro foam, which is very flexible. The result is a high stack sole with 39 mm of height under the heel and 31 mm under the forefoot. The testers found the outcome breathtaking in terms of performance and running sensations. Indeed, they noted "fast transitions" from heel to toe and a perfect balance between softness and bounce. In other words, the feel is soft and plush with the Lightstrike Pro foam, but the carbon plates give good structure and a natural impulse while running. The only downside is the weight of the foam, which is heavier than that of its competitors (such as Nike's ZoomX). The shoe is far from being heavy, but it is not as light as one would expect from this high-tech racing shoe.

The Adidas Adizero Adios Pro also shines thanks to its Celermesh upper that offers amazing foot lockdown with its unique design. Also, it provides excellent airflow throughout the run and features a roomy toe-box without reducing lockdown. The only criticism we've seen is that the collar could irritate the Achilles tendon, but this may be an isolated incident.

Finally, the outsole is rugged rubber but with a surprisingly flat sandpaper-like surface. Rest assured, however, the testers didn't find that this configuration diminished durability or grip—quite the contrary!

In summary, the Adidas Adizero Adios Pro is an excellent running shoe to go fast comfortably that offers a unique and impressive configuration, especially with the EnergyRods carbon plates under the toes. The comfort is there, and the cushioning is spectacular, according to the runners who have tested the shoe.

While not the first Asics shoe to feature a carbon plate, the MetaSpeed Sky is the first in this category with high stack cushioning (33mm under the heel) for the Japanese brand.

The MetaSpeed Sky results from Asics' research. They concluded that athletes could be classified into two categories: those who increase their stride and those who raise their cadence to go faster. The Sky targets the first category, while another model, the MetaSpeed Edge, should be released soon to target the second. So what's the MetaSpeed Sky worth, and is it right for you?

The midsole uses a new nylon-based foam: FF (for FlyteFoam) BLAST TURBO. It's pretty firm without being harsh. Thus, the testers noted that the sole's density is similar to that of the Saucony Endorphin Pro but a little softer. The carbon plate is most noticeable under the heel and midfoot, while the forefoot is softer. Despite the narrow heel, athletes rated the stability as good. According to runners, the rockered design of the sole gives a rather abrupt rocking effect. So while some shoes provide a smooth transition, the MetaSpeed Sky's rolling motion is as sudden as it is effective. So the best is to test it out and see if it works for you. In any case, it reinforces the overall impression of the shoe: this is a model to go fast, very fast. Forget daily training; this is a pure competition shoe. The low drop (5 mm) doesn't improve the versatility: at low speeds, the heel feels heavy and requires a fast pace to activate this "super shoe." Overall, testers unanimously liked the MetaSpeed Sky's explosive cushioning.

Next, the single-layer mesh provides an effective lockdown with just the right amount of space. On that last point, some users found the toe box a bit too roomy. So be careful if you have narrow feet. If you have wide feet, you can count your blessings! Also, the upper's simple design, without overlays, makes it not very pliable to keep the foot in place better. In short, we recognize the know-how and quality of Asics. Finally, the outsole features the ASICSGRIP rubber developed primarily for the trail running collection of the brand. It proves to be both grippy and durable. At first glance, it would seem that the MetaSpeed Sky is one of the most robust "super shoes." To be confirmed, though.

All in all, it took Asics a while to respond to the challenge posed by Nike's "FLY" (the MetaRacer had a much thinner sole, putting it in a category of its own), but it's safe to say that the MetaSpeed Sky doesn't fall short with its cutting-edge configuration. This shoe is for you if you're looking for an elite model to shatter your records over long distances like the marathon.

What happens when you take an already very good shoe that won the accolades of the trail community in 2018 and make it a little better? You get an exceptional model that's close to perfection. Nothing less! Indeed, the Hoka Torrent 2 confirms its reputation as an ultra-versatile, comfortable and lightweight shoe. While the first model had been very well received, some criticized its upper as being too harsh and not safe enough to tackle very technical surfaces, especially downhill. This second version addresses this feedback with an improved upper that translates into a more classic mesh. Paradoxically, it is more flexible while offering a more precise foot lockdown. According to the testers, the result feels very secure without being too tight (the shoe is also suitable for trailers with wider feet). Then, regarding the cushioning, we find the PROFLY double density foam which gives comfortable but fairly firm padding. The absence of a protective plate combined with the moderate cushioning provides excellent ground feeling. This will appeal to athletes who like a good natural ride on the trails. Overall, the Torrent 2 offers a good compromise between shock absorption, protection and ground feel. Thus, trailers who tested the shoe found it very comfortable, even after several hours of running, despite the relative thinness of the sole. Finally, the traction is always impeccable whatever the terrain or the type of elevation. The multidirectional studs are indeed more numerous and slightly more aggressive, which makes it easy to tackle the most technical trails, whether soft mud or slippery rocks. In short, the Hoka Torrent 2 is an excellent trail shoe (maybe even the best of the year!) that proves to be effective and comfortable in all circumstances. A reference shoe not to be missed!

The Brooks Cascadia 16 is a comfortable and versatile running shoe to run on trails. This new version is lighter (finally under 300 g/10.6 oz) while offering more cushioning (29 mm under the heel).

The upper is softer and more spacious, which makes it more suitable for users with wide feet.

The new Brooks Cascadia 16 is more cushioned and softer at the same time. Also, its outsole offers more flexibility. The result is a smoother and more responsive run. Ah, and the legacy Pivot Post system is finally gone, without any negative impact on stability.

The grip is also top-notch. Even if some reviewers note that the profile of the lugs (medium depth) may not be suitable in some rare cases (really technical terrain, such as mud), not much to complain about here.

Finally, according to users, the value for money is good. These trail shoes feature a high-quality, sturdy build for optimal durability—no signs of wear after 50 miles/80 km—and comes with a reasonable price of $130 (expected retail price).

Please read our complete review analysis of the Brooks Cascadia 16 for more information.

Hoka is perhaps best-known for its Clifton and Bondi models, but the Mach line has gained traction with its newest addition: the 4. Lightweight, supportive, and built to go the distance, this running shoe performs head and shoulders over previous Mach models.

Weighing 8 oz/227 g with a stack height of 29 mm, the 4 is fairly lightweight given its superb midsole cushioning. While the Mach 3 earned itself a reputation for its firm and structured configuration, the Mach 4 is noticeably plushier. Engineered with PROFLY technology, you'll enjoy a smooth, padded ride that makes it easy to fall into an effortless rhythm. The impressive midsole is combined with a breathable mesh upper that fits true-to-size and an EVA rubber outsole that grips the road. The result? A durable shoe that's made for hundreds of miles of use without showing any signs of wear. Runners remarked that the shoe never gave way even on longer rides—after 40 miles/65 km, the wear was barely visible.

Among much positive feedback, there were just a few cons noted among those who tried the Mach 4. One of these included needlessly long laces; besides, this model sacrifices some responsiveness (compared with trainers from other brands). Also, the upper, while airy, felt warm for some testers. As a final note—though more of an observation than a drawback—the Mach 4 is not a sprinting shoe. Although tempo training is definitely up its alley, fast runs in this model seem to require more effort. However, for mid to long, steady rides, most users had only good things to say about this new model.

In short, the Hoka Mach 4 is an excellent surprise that marks a milestone in the Mach series. Testers have been unanimously seduced by its lightweight, long-lasting and lively setup. If you're looking for a comfortable trainer meant for serious mileage that can handle a variety of paces, then look no further; you've got yourself a shoe!

The New Balance 1080 v10 is a comfortable and versatile road shoe with generous cushioning. Indeed, it has a 29 mm thick sole under the heel with an 8 mm drop. It features the Fresh Foam technology that is used in many New Balance models. On this particular model, the foam provides a comfortable and soft cushioning while offering a good energy return. In comparison, the cushioning is softer than on the Beacon v2, for example. This configuration provides a comfortable running feel to have fun over long distances. Nevertheless, this model retains the excellent polyvalence for which it is renowned and adapts very well to shorter distances and speed training. The upper area features the most changes with a new flame design for the heel to better support the foot. In addition, the new upper now uses knit instead of mesh. This provides optimal ventilation and a slightly softer fit. Another important point is that you can comfortably splay your toes thanks to the large toe box. All in all, the New Balance Fresh Foam 1080 v10 is a very good surprise with some important changes that considerably improve comfort. An excellent, comfortable and versatile road running shoe not to be missed!

With the Endorphin Pro, Saucony enters the highly-competitive carbon plate running shoe category that has been dominated head and shoulders by Nike so far.

It's a lightweight shoe (221 grams for men, 190 grams for women) with a thick sole (35 mm under the heel) that features a brand new cushioning technology: PWRRUN PB. It translates into Pebax fused granules with a texture reminiscent of Adidas Boost. Inside, the carbon plate is there to make the ride more responsive by facilitating a snappy rebound. So what's the verdict?

First of all, what surprised testers the most was the firmness of the cushioning despite the high stack height. They note that the cushioning is very bouncy but without offering the "trampoline" effect of the Nike ZoomX Vaporfly NEXT%. This configuration has the advantage of giving a more stable and natural ride with a good ground feeling. It may not perform as well as the Nike Vaporfly—only time will tell—but overall, Saucony's approach is convincing and original.

Regarding the upper, the FORMFIT mesh gives a strict foot lockdown for more safety when you go fast. The runners were impressed by the excellent ventilation of the foot during the effort. However, the shoe has a tapered profile, so it can be too narrow if you have wider feet.

Finally, the carbon rubber of the outsole ensures good durability and excellent traction on urban surfaces.

All in all, the Saucony Endorphin Pro is a very good carbon-plate running shoe that's already a solid contender to Nike's NEXT% collection.

The Hoka One One Speedgoat 4 is a trail shoe inspired by the legendary ultramarathon athlete Karl 'Speedgoat' Meltzer. With an excellent third model, we were looking forward to this fourth iteration. On the one hand, it is sometimes disappointing to find a new model with few improvements, but on the other hand, it is reassuring to see an excellent shoe keep its substance and not change radically. As the saying goes, you don't change a winning team! Thus, the Speedgoat 4 is very similar to the SG3 with some notable improvements. Cushioning is still as comfortable and responsive despite the introduction of a new injection-molded EVA foam. The Speedgoat is a maximalist shoe with 32 mm of thickness under the heel and thus effectively absorbs shocks on the most challenging terrains. However, it is not soft and offers an excellent return of energy for a bounce-filled racing feeling. It's one of the main assets that make it an exceptional trail shoe. Also, the SG4 is a low drop shoe with a 4 mm offset between heel and toes. The upper is the part that features the most changes. Indeed, reputed to be too narrow in the past for many athletes, it is now wider at the toe level and no longer compresses them uncomfortably. So the shoe should now be suitable for as many people as possible. Make no mistake though: the upper remains relatively firm with limited flexibility, but this configuration has the advantage of providing an effective foot lockdown. It makes you feel safer on very rough technical terrain where stability and secure fit are essential. Also, the mesh is robust and breathable. Finally, the grip is always at its best with a Vibram outsole with 5mm lugs that provide excellent traction in all conditions. In short, the Hoka One One Speedgoat 4 is an excellent trail shoe ideal for long distances on the most technically challenging trails.

After the elite shoes for competition, the Nike ZoomX range tackles daily training with the Invincible Run. It's a model with maximal cushioning (37 mm sole under the heel, 28 mm under the forefoot) made for comfort and determined to go head to head with Hoka, who dominates the category. It seems that Nike had this model in the making for a few years already, but the wait was well worth it. Indeed, the Invincible Run already appears as one of the most exciting running shoes of the year.

Let's not prolong the suspense: the testers were blown away by the cushioning - nothing less! The midsole is both soft and bouncy with excellent shock absorption and protection. In general, you get bounce or softness, but it's rare to have both in one shoe. With the Invincible Run, it seems that with ZoomX, Nike has found the magic formula to offer a snappy and plush ride for daily training. However, there's a small caveat: the midsole of the Invincible consists only of foam. Therefore, there's no Air unit or carbon plate to give structure and improve stability. To compensate, Nike has considerably increased the width of the shoe, especially at the heel. The result is mixed, with some testers noting a slight instability at times.

The upper is Flyknit but looks more like a classic mesh than Nike's famous breathable and stretchy knit. On this model, it's dense and rather strict to ensure a more precise foot lockdown. It's consistent with the wide platform for improved stability. The foothold is excellent according to the runners and, the cherry on top, the toe box is ample enough to accommodate wider feet. The only weak point noted is the thick ankle collar, which locks-in the heel but can potentially irritate with friction.

Finally, the outsole is all-rubber with very thin lugs. Traction is flawless, and durability seems to be there at first glance—time will tell.

All in all, the Nike ZoomX Invincible Run delivers on its promises. It's a relatively lightweight trainer (278 g/9.8 oz for men, 245 g/8.6 oz for women) with soft, maximal, and responsive cushioning that has left more than one runner amazed by the ride it offers. The only downsides are the slight lack of stability and the thick collar, but these are not significant problems. The price is another story: $180 is a hefty sum for a model intended primarily for daily training and recovery.

Nike expands its NEXT% collection with a new model to complement the Alphafly: the Nike Air Zoom Tempo NEXT% Flyknit.

What immediately grabs the attention is its massive sole (46 mm stack under the heel!) with a curved shape that looks like an arch. Another important point is its nylon plate. It improves propulsion by ensuring a smooth transition while running. The big difference compared to a carbon plate (like the one on the Alphafly) is its firmness: carbon is lighter but firmer than nylon. Thus, the blade on the Tempo is softer, which makes it less noticeable.

In terms of running sensation, runners found the cushioning of the shoe very comfortable while being rather firm underfoot. This configuration makes the platform relatively stable despite the impressive stack height. As a result, the shoe is more stable than other models equipped with ZoomX foam. According to them, this is the work of the React foam under the heel. They also found the ride pleasant and responsive even at a slow pace, which is not always the case with propulsion plate running shoes as they are primarily intended for racing and fast speeds. Nike seems to position the Tempo as a fast and versatile trainer with its medium weight (252 g) and nylon blade, and the Alphafly as a competition shoe with its carbon plate and featherweight.

Moving on to the upper, Flyknit is quite breathable despite its somewhat "plastic" appearance. It is not very stretchy for a more precise foot lockdown without reducing comfort. The shoe remains spacious overall, especially in the toe area. However, some runners have found it too narrow in the midfoot, which may not be suitable for everyone.

Overall, the Nike Air Zoom Tempo NEXT% Flyknit is a very good, comfortable, and versatile trainer with high-stack yet firm cushioning and a nylon blade.

The star of Nike's running collection is back! This update to the OG carbon-fiber plate shoe doesn't feature many changes, except for the new upper that received mixed reviews.

The stack is still high with 40 mm under the heel and 32 mm under the metatarsals (8 mm drop). The carbon plate and ZoomX foam provide soft, bouncy cushioning with a snappy toe-off to improve your performance and shave a few precious minutes off your personal best, especially over long distances like the marathon.

The upper of the Nike ZoomX Vaporfly Next 2 is about comfort with an even more breathable mesh and more padding for a softer lockdown. The toe box is also wider to fit more feet. However, some testers were disappointed with the foot lockdown, which they felt was too imprecise for a racing shoe of this caliber.

Finally, the outsole offers a good grip even if the durability is still a delicate point—unfortunately, it's often the case with this type of shoe.

Overall, the Nike ZoomX Vaporfly NEXT 2 maintains its elite status. However, if you can find the first model reasonably priced, we see little reason to opt for this 2021 version.
