The Best Trail Running Shoes: The Ultimate 2021 Ranking

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 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.

The Altra Olympus 4 is a trail shoe with a high-stack sole (33 mm), zero drop (so no offset between heel and toes), and a wide platform. This new version is more refined, however, which gives the shoe a more streamlined and less massive design. However, it retains the qualities that have made it so successful. Its high-stack cushioning ensures comfortable shock absorption throughout the run. Also, the running sensations are responsive with an enjoyable bounce. Of course, with its relatively heavy weight (318 g for men, 289 g for women), this is not a model made for speed and daring descents. The Olympus is a trail running cruiser that's all about comfort. It shows in the upper with a mesh that now has an open texture for better ventilation. The result is a pleasant and rather ample lockdown (be careful if you have narrow feet). The toe box is spacious as on all Altra models. Finally, the grip is very good with a Vibram MegaGrip rubber sole that features moderate lugs. The configuration is sturdy and can take a beating according to trailers who tested the shoe. Thus, the Olympus 4 is a comfortable option for medium difficulty trails (its ample foot lockdown and not-so-aggressive lugs don't make it the best choice for the most technical surfaces). A very good shoe for trailers looking for maximum comfort for their long trail runs.

The Salomon shoe specially designed for ultra trail running is back. The S/Lab Ultra 3 is a versatile shoe favored by French star François d'Haene, a three-time UTMB winner. So what is this new version worth? First of all, the configuration remains almost identical in terms of weight and stack height. The grip is still excellent with the Contagrip rubber and its moderately aggressive lugs. The Ultra 3 is comfortable on most terrains, although testers note that deeper lugs would be welcome on steep and muddy routes. Also, as with previous versions, the configuration is robust and wear-resistant. In terms of cushioning, the stack height is moderate, with 26 mm under the heel and 18 mm under the forefoot. Trailers characterize the cushioning as "fairly firm" while offering good flexibility and shock absorption, which makes the ride enjoyable even over long distances. They also describe the feel of the run as springy, with smooth transitions throughout the run, even at low speeds. Then, the upper is softer with a streamlined, seamless design that gets rid of the "wings" of the previous model. The foot lockdown is great, resulting in a stable and safe run. Also, the upper is slightly more spacious (especially in the toe area), and its flexibility ensures good freedom of movement for the foot. The only negative point of the upper would be its lack of ventilation. Besides, despite all its great qualities, the shoe is on the expensive side with a base price of $180. In summary, the Salomon S/Lab Ultra 3 is a very good trail shoe that is comfortable in all conditions and offers great comfort over long distances.

The Peregrine reigns over Saucony's trail range alongside the Xodus. It's a peppy shoe with fantastic versatility that continues to impress despite its persistent bulky weight.

The outsole and its lugs are almost identical to those of the P10—and still just as effective! They offer impeccable grip on the most technical surfaces. It's even possible to add ice screws if needed. Besides, there's the ST (Soft Terrain) version for soft surfaces such as mud. It comes with 6.5 mm lugs compared to 5 mm for the standard and GTX versions.

The stack height is higher than before, with 27 mm under the heel and 23 mm under the forefoot. The foam used is still PWRRUN with a similar medium density, slightly firm, cushioning. The midsole absorbs shocks well while still allowing some ground feel. This configuration is beneficial on technical terrain as it provides good stability while ensuring a smooth run.

Finally, like the rest of the shoe, the upper shows no radical change but rather small touches here and there, such as a thicker tongue and a better overlay system. It gives a secure lockdown and adequate ventilation with plenty of toe room—the forefoot part is not as roomy as an Altra, but it will fit most runners.

In summary, the Saucony Peregrine 11 continues to dominate the trail category with a powerful configuration for a wide range of terrains and situations thanks to its outstanding foot lockdown, protection, and grip. The slightly firm cushioning may not appeal to you if you like plush padding, but it's a matter of preference. This model's real weak point (as with its predecessors) is its weight, with 10.9 oz/310 g for men and 9.5 oz/270 g for women. Let's hope Saucony can hear us on that one!

The Nike Zoom Terra Kiger 6 is a lightweight trail shoe that offers a good balance between ground feeling and protection. Let's say it right away: this new version brings few fundamental changes after the thorough redesign of the previous model. If you liked the Kiger 5, you will not be disappointed by the K6. It features a dynamic and versatile cushioning that's ideal for tempo-style speed sessions on trails. The shoe offers good shock absorption without isolating the foot from the ground. With a stack height of 24 mm under the heel, cushioning is therefore moderate. However, it should be noted that some runners have found the heel particularly rigid which can be disconcerting given the flexibility of the forefoot. Then, traction is always very good on trails of medium technical difficulty. The moderately deep lugs give a good grip, especially in the mud. The non-slip rubber triangle in the middle of the outsole divides runners: some find it effective while others would prefer lugs as on the rest of the sole. Finally, the main change is in the upper. The support is now more precise without being strict. In addition, the toe box is also more spacious for more comfort. In summary, the Nike Zoom Terra Kiger 6 is a very good trail shoe that still offers a great ride for daily training. PROS

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.

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.

Nike expands its trail collection (which already includes the Wildhorse and Terra Kiger) with this second Pegasus Trail model. Rather than a direct successor of the Nike Air Zoom Pegasus 36 Trail released in 2019, the Pegasus Trail 2 appears as a combo of various recent Nike models like the Vaporfly and the Turbo 2. For example, the React foam now equips the entire sole (there are no more Zoom Air units). The stack is relatively high with 31 mm under the heel and 21 mm under the forefoot. The midsole is soft but the rubber of the outsole compensates with its firmness which prevents the cushioning from being overly soft. Trailers have been impressed by the comfort and bounce of the cushioning. They also found it to be very versatile, i.e. suitable for all paces and terrains. Besides, even without the rock plate, they did not feel any pain after several hours of running. The only negative point would be the lack of stability on uneven surfaces due to the softness of the cushioning. Combined with the flexible upper, this somewhat limits the effectiveness of the shoe on very technical terrains that require a secure balance and precise foot lockdown. The upper is made of a solid mesh with a small rubber toe cap at the front. It's well ventilated to allow the foot to breathe during the effort. The toe box is relatively wide but some runners found it a little low. However, they note that this problem disappears over time as the mesh loosens. There is also a 'faux' (integrated) gaiter to better protect the foot as on the Wildhorse. Finally, the grip is also very good thanks to the rubber outsole and its wide lugs of medium depth (about 3 mm). The traction can come up a bit short on very soft mud and compact snow but allows you to also run on the road, which is ideal if you like to alternate. Overall, the Nike Pegasus Trail 2 is a very good, comfortable, and versatile trail shoe with responsive cushioning to have fun on most terrains.

The Hoka Challenger ATR is the comfy trail running shoe for your long Sunday runs on easy trails where you take the time to smell the flowers. This sixth version uses the same formula with a new improved upper.

The new engineered mesh is not only good looking and nicely fitting, it also uses recycled plastic, which is a step in the right direction sustainability wise. Some people found the ATR 5's mesh a little too loose around the midfoot, and Hoka fixed it with the 6. The lockdown is rather tight but pleasant and breathable. However, some runners with wide feet described the toe box as a bit narrow, so be careful if you have experienced such issues in the past.

Then, the CMEVA midsole with a stack height of 29 mm under the heel and 5 mm drop gives a soft cushioning that has the advantage of comfortably absorbing shocks but reduces the ground feel. It also seems that the front part is not very flexible, according to some trail runners. Fortunately, the Meta-Rocker brings a slight bounce to the platform for a smooth ride overall.

According to the testers, the grip is, as on the previous models, satisfactory but a little light for technical terrains such as mud or rocks. Thus, stability is not always optimal, especially since the platform is not so wide. The Hoka Torrent 2 or the Speedgoat 4 seem to be the best choices if you have tough trails in mind or an ultramarathon with many different layouts. Finally, in terms of durability, the outsole showed signs of wear after just a few runs on rocky terrains for some users. It's not necessarily a massive problem since the Challenger is not primarily intended for this type of terrain, but it's not reassuring either.

To summarize, the Challenger ATR 6 is a very good choice for long easy runs. Its versatile and comfortable configuration makes it suitable for moderate trails and even allows you to venture out on the road. We recommend it to rest your feet from more technically advanced footwear.

The Brooks Caldera 5 is a trail cruiser built for comfy long-distance running. A near-identical shoe to its predecessor, this trainer provides a smooth ride and easy turnover for uphill runs. Secure, grippy, and surprisingly versatile, the Caldera 5 is one model that should be on any trail runner's radar.

First things first: runners had quite a few thoughts about the C5's midsole. As with other Brooks models, this latest is engineered with BioMoGo technology, prioritizing shock absorption over pop. However, users noted that this particular midsole wasn't as harsh as previous models. The mono-loop engineered upper has significantly improved from previous Caldera models, with a more dialed and precise toe box fit. Its laces enable above-average foot security, and the toe box remains wide enough to accommodate most types of feet. However, some runners noted that the forefoot fit was a bit more tricky than in the past. Lastly, the TrailTack outsole tackles a range of surfaces, despite its lugs' low and narrow profile. It's thriving on flat and technical terrain alike. However, a few trail runners note that the Caldera 5 may not be the best option for highly technical landscapes, especially soft ground like mud.

As with most shoes, the Caldera 5 isn't perfect. One area it falls short is stability: the high stack height combined with a somewhat narrow profile makes the heel feel a bit unstable at times, according to some runners. The Brooks Caldera 5 also loses points on its BioMoGo midsole, which doesn't contribute to a fast or responsive ride. The weight doesn't help either: with a weight of 10.6 oz (301 g), it's undoubtedly no feather. Also, the shoe as a whole seems to require a more extended break-in period than previous models.

Ultimately, the Caldera 5 is a reliable Brooks trail option for runners interested in comfortably tackling long distances on moderately technical terrains. Available for a standard price point for a shoe of this caliber, the C5 is good value for money!
