The Best Running Shoes of 2021

Brooks has delivered dozens of times over the years with running shoes that perform. However, their latest model—the Adrenaline GTS 21—might take the cake for bestselling stability trainer. Touted for its smooth ride and adaptable support, the brand has done it again with a reliable, no-frills shoe geared for daily runs.

Perhaps the most notable feature of the Adrenaline is its stellar midsole. Its DNA Loft and BioMoGo DNA technologies provide the best of both worlds with the perfect balance of comfort and security. The cushioning makes it a great shoe for longer rides and daily use. The upper is breathable and supportive with an updated engineered mesh. Brooks has also continued implementing GuideRails support technology on their stack, extending it to the Adrenaline GTS. It's supposed to ensure that a runner's feet and knees remain aligned, providing as much security as possible. While we generally don't advocate for support shoes in the absence of probing scientific proof, some runners swear by it. Hence, it's definitely an option to consider if you're having difficulty finding comfortable shoes. The outsole's segmented crash pad is sturdy and lends itself to good traction so that runners can enjoy a secure grip on the road.

There's no doubt that the Adrenaline GTS is more than capable of performing as a stability shoe. In fact, it's one of the strongest stability options on the market. That said, runners shouldn't expect a noticeable bounce or lively spring with each stride. Instead, this Brooks model focuses on providing a smooth ride that's durable and reliable for your daily run. It's not recommended for sprints or faster workouts. Some users also suggested that a lower heel drop-off would be preferable.

In summation, the Adrenaline GTS does everything a good, long-distance stability trainer should. In addition to offering steady support, it's great for marathons and recovery days alike. Available at an average price for its caliber, it may just be the shoe for you!

Maintaining all of the best parts of its previous model (Freedom 3), Saucony's latest Freedom 4 is now available. The brand's Freedom line is praised by U.S. Olympian Marathon Trials runner-up Molly Seidel, who used the 3 for gym workouts and running. Ultimately, Saucony has perfected and built on the Freedom 3 with its latest model. Great for everything from walking the dog, to gym sessions, to road running, the versatile 4 can do it all.

Perhaps one of the most significant improvements to the 4 may be found in the midsole. Made with PWWRUN PB technology—so far reserved for the plated models of the brand—the 4 is firmer, livelier, and doesn't contain a plate. Runners said that overall, the midsole's medium-level cushioning was great for tackling longer distances and snappy enough for faster speeds. It is a bit sturdier than the 3, yet still retains flexible properties and provides quick turnover when necessary. The upper is lightweight and soft while protecting the foot with a medium-mesh and thick, gusseted tongue. Finally, the outsole is composed of full-coverage rubber, which grips well to virtually any surface. It provides good stability, traction and lends itself to a decent "pop" when used on the road.

Runners didn't have much that was negative to say about the Freedom 4. One common remark was that the 4 is less soft and flexible than its preceding model but still performs well. It's also not the best shoe for regular, longer rides (though it can go the distance when necessary). One other note: the shoe tends to be a bit flat, requiring more effort to achieve a decent spring, according to a few testers. Apart from these technicalities, the latest Freedom model is a true upgrade from previous versions.

In short, the Saucony Freedom 4 is a lightweight, versatile, and comfortable trainer that can handle pretty much anything you throw at it. While this new version may not be as soft as its predecessors, its lively ride makes it worth considering.

Nike just released the Terra Kiger 7, and longtime fans are crying foul: this seventh version, much more cushioned, has little in common with the first models, they claim. So what's the verdict?

First, the new Terra Kiger is bulkier with a thicker sole and a roomier upper. Sadly, the weight has also gone up. The stack increased by 3 mm and is now 30 mm under the heel. In other words, after flirting with minimalism in its early days, the Terra Kiger has decided to supercharge its cushioning to go the distance. Like the previous model, it features React, Nike's most popular foam right now (alongside ZoomX). This new configuration has the advantage of offering comfortable cushioning in all circumstances. Also, the segmented rock plate provides a high level of protection for added safety. Trail runners note that the TK7 delivers comfortable cushioning while keeping its signature ground feel despite the higher stack. However, they didn't find the ride exceptionally responsive, even with the Zoom Air unit now located under the forefoot for a more effective toe-off.

Next, the outsole features more rubber and larger lugs for a more effective grip. Trailers criticized the non-slip diamond-shaped zone without lugs in previous models for its lack of effectiveness, and Nike has finally addressed the problem. Another improvement is that the rubber under the heel is less rigid, giving greater flexibility for a more stable grip.

Finally, the upper is roomier without sacrificing foot lockdown. The mesh/synthetic configuration with the Dynamic Fit system is secure even on difficult downhill paths.

In summary, the Terra Kiger series takes a new direction with this version 7. More cushioning, more protection, better grip: while some may regret the early lightweight days of the KT, many will be glad to take it for a spin on long and technical terrains.

The Saucony Triumph 18 is the ultimate everyday trainer with comfortable cushioning and an upper that fits most runners. With a 33 mm stack height under the heel (25 mm under the forefoot), the Triumph 18 is one of Saucony's most cushioned shoes. It now features PWRRUN+ foam, which gives a soft cushioning that comfortably absorbs shocks without being too soft. The shoe provides good stability, so the high-stack cushioning does not reduce balance while running. Overall, the runners found the cushioning lively but not bouncy by any means. Unfortunately, this reduces the versatility of the shoe: it's pleasant during daily training at low or medium speed but not for speed workouts (e.g., tempo, interval). However, on the plus side, testers note that this new model has the advantage of having a smaller heel than previously for better stability and offers smoother transitions. Then, the upper is still excellent with a comfortable and effective foot lockdown. The engineered mesh is relatively thick while remaining breathable. However, given the extra weight of this new version (over 300 g/11 oz) and the natural stability of its platform, testers wondered if such a thick and elaborate mesh was essential. Finally, there is the new XT-900 (carbon) rubber on the outsole, which provides a good grip and protects the shoe from wear and tear. To summarize, the Saucony Triumph 18 is a very good running shoe that will delight runners looking for a well-cushioned shoe for regular training and long runs. However, if you want a snappy shoe to run fast, then its heavyweight and lack of springe may not be ideal.

Summer is around the corner, and with it, the new version of this Nike classic: the Nike Air Zoom Pegasus 37. This new model has undergone some significant changes, including a new upper and cushioning. React foam is now under the heel and midfoot, while a thicker and wider Zoom Air unit equips the forefoot. The latter is noticeable under the forefoot and can improve the shoe's bounce, especially when the foot pushes the ground to propel the body. It's important to note that Zoom Air cushioning is softer on the women's version than on the men's model. According to studies carried out by the brand, women prefer softer cushioning than men. Overall, this new configuration with React foam, known for its flexibility, gives a softer cushioning than on the P36 while remaining relatively firm overall. The shoe divides testers between those who find the cushioning perfectly adequate and those who blame it for lack of responsiveness to really have fun. The thickness of the sole remains unchanged, with 28 mm under the heel and 18 mm under the forefoot (10 mm drop). The new translucent engineered mesh is breathable and offers precise socklike foot lockdown: neither too loose nor too tight. Also, its sleek design without the Flywire cables (replaced by a band) is quite stylish. Runners agree that the upper is near perfect and marks a clear improvement over the previous model. The outsole provides good traction in urban areas and has a thick rubber layer to last a long time. Finally, it's interesting to note that the shoe is, unfortunately, slightly heavier than before, with 20 grams more. All in all, the Nike Air Zoom Pegasus 37 stays the course despite significant changes and continues to establish itself as a comfortable and versatile shoe suitable for virtually every runner. Only its cushioning has disappointed some runners, but it's a matter of preference, and we invite you to try it for yourself.

The Hoka Arahi 5 is a support running shoe geared for daily workouts. This latest model comes with a significantly improved fit that hugs feet and delivers optimal support. According to runners, the difference between the 4 and the 5 is huge—and there are several reasons why.

First, let's start with the shoe's midsole, which lends itself to a stable yet supremely comfortable ride. While the Arahi 4 and 5 feature comparable midsoles, runners noted that the 5 offers more padding with the same drop and stack height. The ride is still on the firm side and the bounce minimal, though the Meta-Rocker Geometry allows smooth transitions.

The new and improved upper design—arguably the shoe's selling point—is fast-drying, supportive, and secure. Compared with the Arahi 4, which runners complained was a bit too voluminous, the 5 feels like a more streamlined experience. What's more, the targeted fit doesn't make the shoe more narrow—it's still suitable for runners with wider feet. Finally, the shoe's outsole is built for durability and performs in wet weather and steep slopes alike. While the A5 is a road running shoe, it's suitable for easy dirt tracks.

Overall, the Arahi 5 may be a great daily trainer for runners who value distance over speed. Because it's a stability shoe, it's not designed for races or speed work. However, the potential for a faster pace still exists!

Ultimately, Hoka hit it right with this new version. The 5 is a practical, reliable, and attractive road shoe with long-term potential—built to accommodate distance and stability.

The Clifton is undoubtedly one of the most popular shoes in Hoka's range. After some wandering that was not to the liking of every fan, the Clifton has made a nice comeback in recent years. This eighth version follows the same approach with some changes. Let's go through it together.

First of all, the Clifton is famous for its soft and flexible cushioning within the Hoka series. In this respect, the Clifton 8 is even softer than its predecessor! It's particularly noticeable under the forefoot. According to the American brand (formerly French), the foam is new, lighter, and more springy. However, in practice, the weight remains similar (250 g/8.8 oz for the men's model), and the energy return is satisfactory without being breathtaking. According to some testers, the Clifton delivers a smooth ride. Still, it suffers from the comparison with the last generation of foams (ZoomX by Nike or PWRRUN PB by Saucony, for example) which decided to abandon EVA for Pebax. Last but not least, the famous Meta-Rocker of the brand enables quick transitions from heel to toe by compensating for the low drop (5 mm).

Next, the upper is the part where we find the most significant changes. First, let's appreciate that the mesh is now 100% vegan! The story doesn't say if the sole is also vegan (so we assume it's not), but it's already a good start and shows that the industry is heading in the right direction. The mesh is thinner, which gives better breathability. Also, the new padded gusseted tongue locks in the foot securely and comfortably. The only tricky part is the size of the upper: wide-footed athletes will be happy to know that the upper is higher and wider. However, people with thinner feet may have fit concerns (no pun intended). So be careful if you're in that situation!

Finally, the outsole packs a good amount of rubber in sensitive areas to protect them from abrasion. Traction is adequate, but runners note that the Clifton may not be as stable as the Mach 4, which offers a wider heel (Swallow Tail). Testers report that the stability is better than with the early versions, but there's still room for improvement.

All in all, the Hoka Clifton 8 is a very good running shoe with a soft, high-stack, and flexible platform that packs sufficient bounce to have fun during your daily runs. Plus, the added softness of the midsole makes it more versatile so that you can use the Clifton for any speed or distance. A solid reference that lives up to its reputation!

The third model of the very successful Endorphin collection is a tempo running shoe: the Speed. Complementing the Endorphin Shift (trainer) and Endorphin Pro (versatile with carbon plate), this shoe stands out for its snappy ride at fast paces. Its neon hues and fun design also make it a very appealing shoe. The Speed's midsole is one of the most notable features of this model. Made with PEBA-based PWRRUN PB cushioning, Saucony claims that this material offers an explosive energy return. This high-stack shoe (33 mm under the heel, 25 mm under the forefoot) also features a full-length, S-curved nylon plate, and SpeedRoll geometry to provide a smooth and comfortable transition from heel to toes. Testers unanimously enjoyed the ride, but with one caveat: you have to run fast as the shoe is a bit too harsh at slow paces. The Speed is noticeably much lighter than the Endorphin Shift, giving it a more weightless feel. Runners remarked that the upper of the Speed is particularly excellent, with FORMFIT technology that enhances comfort and breathability. Meanwhile, the outsole contributes to the propulsion of the shoe, engineered with durable rubber that grips terrain and stabilizes the foot. Those who tried the Speed commented on a few drawbacks of the design. The rear and plate of the shoe, though cushioned, proved a bit too firm for some runners. However, this rigidity lessened overtime. Runners also questioned the price point of the Speed, which is $40 less than its Pro counterpart but doesn't offer the same versatility and comfort. The Speed is a great tempo shoe, meaning that it works well for interval or tempo runs, but it is not a daily trainer. Runners searching for running shoes suitable for all workouts will prefer the Pro over the Shift. Overall, the Saucony Endorphin Pro is a very good running shoe with comfortable and responsive cushioning for fast running, even though its firmness may not be to the liking of everyone.

The Mizuno Wave Rider 24 has become a household running name. It's a shoe that has remained relatively constant over the years, especially with its Wave plate, which can be considered the ancestor of modern carbon plates. However, this twenty-fourth version has a major new feature: the Mizuno Enerzy foam. Without replacing the famous U4ic, it complements it and softens the ride of the shoe with its greater flexibility. Thus, while the Mizuno Wave Rider has always had the reputation of being firm, the MWR24 is more forgiving. Overall, runners appreciated the cushioning, noting a good balance between cushioning and bounce. However, some complained about the Mizuno Wave plate, which, according to them, "is useless and makes the shoe heavier." On this subject, let's note that the Wave Rider 24's weight is reasonable, with 281 g (9.9 oz) for men and 232 g (8.2 oz) for women. Secondly, the new Air Mesh was also very well received. Testers note that it marks a clear improvement over the Waveknit mesh that Mizuno has been pushing in recent years on some of its models. The mesh is thick while ensuring good airflow in the shoe. Besides, the upper uses fewer overlays without reducing the effectiveness of the lockdown. Finally, the outsole is equipped with carbon rubber in certain areas to improve traction and protect the shoe. On this last point, runners were a bit disappointed: they note that the unprotected parts (made of exposed foam) tend to wear quickly. In summary, the Mizuno Wave Rider 24 makes great strides (pun intended) with a new, slightly softer cushioning and an improved, more comfortable upper—a very good model for daily training.

The Brooks Cascadia 15 is a versatile trail shoe prized by ultra-trail star Scott Jurek. This new model capitalises on the previous version that brought a breath of fresh air to the Cascadia collection. We find a platform as comfortable and versatile as ever equipped with the TrailTack sole and its multidirectional studs. The grip is impeccable on all types of terrains. The main change resides in the upper: there is a new mesh more tightly woven than before, reminiscent of the Caldera 4. This provides better protection even if the ventilation is slightly affected. The upper provides excellent foot lockdown while still being loose enough to be comfortable, especially for the toes. Regarding the cushioning, we find a moderately thick sole with a 24 mm full stack-height under the heel and an 8 mm drop. The midsole offers a good ground feeling, slightly firm, while effectively absorbing shocks. However, testers note that it lacks a bit of bounce and responsiveness to be really fun for speed workouts. In other words, comfort is there, but a little more bounce would be much appreciated. Nevertheless, the shoe has the advantage of being stable. It incorporates a system of pivot points (Pivot Posts) that provides good support, especially downhill. In summary, the Brooks Cascadia 15 is a very good trail shoe that combines comfort, protection, grip and durability but that misses a snappier bounce.

Nike's star trainer is back: the Air Zoom Pegasus 38! The previous model marked a significant overhaul in the series (with notably the introduction of React foam). The Pegasus 38 carries on down this path with only a few changes to report. This new model keeps what worked on the 37 and course corrects the few things that disappointed runners.

Let's start with the elements that don't change much: the midsole, with its React foam and Air Zoom unit, continues to offer comfortable and smooth cushioning. Nothing spectacular in terms of responsiveness—this is a point that inevitably comes up every year. At the same time, it's not in the DNA of the Pegasus. For a bouncier trainer in the Nike range, we recommend the Nike ZoomX Invincible Run. The stack height is still 28 mm thick under the heel and 18 mm under the forefoot (the drop is 10 mm). So it's a good option for athletes who like good cushioning while staying clear of maximalism. In terms of underfoot feel, male testers note that the sole is a little softer than before, while female testers report a bit more firmness (the configuration is slightly different between men and women). Overall, the cushioning is of moderate density.

The rubber outsole gives a good grip and seems sturdy. The main change here is the use of Nike Grind (post-industrial recycled materials) up to 9%. Nothing to shout from the rooftops, but it's a start! One important point flagged by a couple of reviewers: it seems that there are some early signs of sole wear ("creasing" to be exact), so that's something to keep an eye on.

Let's move on to the upper, which concentrates most of the changes. The forefoot is higher and wider, which will delight people who need volume. Some testers complained of some heel slippage with the P37, and Nike adjusted this part for a more secure lockdown. On the other hand, the midfoot webbing allows the upper to hug the foot more evenly when pulling on the laces. Finally, the tongue is longer and more padded. The Pegasus has always offered an impeccable lockdown, and this 38 version is no exception.

The Consensus

In summary, the Pegasus is unsurprisingly... a Pegasus: comfortable, durable, well-fitting, and affordable! While the ride won't knock your socks off, it's a reliable shoe that has the merit of being suitable for everyone (or almost)—a star trainer for everyday use that continues to win the popular vote.

Crafted specifically for taking on tough mountain trails, the Merrell MTL Skyfire is the perfect shoe for higher elevations and shorter running stints on uphill terrains. Its lightweight design (9 oz./242 g) coupled with its great traction and breathable fabric makes the MTL Skyfire an extremely prudent choice for off-trail runners. Its stack dimensions are 23.5mm/17.5mm, with a drop of 6mm and lugs of 5 mm, to provide the best possible running conditions on rocky slopes. Runners who have tried the MTL Skyfire remarked that the sneaker was bouncy, comfortable, and provided a smooth running experience, though there is some discrepancy regarding adequate cushioning, which tends to be a stronger preference for female runners than male runners, according to recent studies. Runners have also stated that the MTL Skyfire is highly breathable, but that this design comes with the pitfall of absorbing a significant amount of moisture straight through to the foot on wet trails, or in rainy weather. MTL Skyfire users have also commented on the narrowness of the sneaker design, which is likely intentional to provide a snug fit for added security on rocky trails. This may make the shoe a great option for runners with narrow to medium feet but may prove too tight for runners with wider feet. For best results, runners who tried the MTL Skyfire recommend tying the laces as tightly as possible for added heel and ankle protection, though this may be unsustainable and prove to be too uncomfortable for longer runs. Note that while the Merrell MTL Skyfire is ideal for shorter running sessions, cross- country runners will likely do better with the sneaker's companion, the Long Sky. Runners were also a big fan of the Merrell MTL Skyfire's reasonable price of only $100, which is relatively budget-friendly compared with other sneaker brands of the same high caliber. Overall, the Merrell MTL Skyfire is a very good running shoe for off-trail, short-distance runners looking for a snug fit, lightweight design, above-average traction, and a great overall value! Longer-distance runners, or those who prefer a bit of extra cushioning, will do well to consider the brand's Long Sky option as an alternative.
