We are so pleased to add the Salomon S/Lab Ultra 3 to our lineup because it absolutely crushed the competition. A new favorite for our testing team and a go-to for all types of running missions, this is the shoe to buy if you want one that'll do it all. We used it for everything — from technical ridge missions to fast road runs, it performs. We love the responsive midsole, super sticky outsole, and breathable upper that seems to protect from every type of particulate. This unisex shoe seems to do it all and is one we recommend to all our friends, including you.

While this shoe, performance-wise, is pretty amazing, the price is a hard one to swallow. The fit, even when converted for women's sizing, also feels large, so we recommend sizing down if you like a tighter fit. Lastly, the collar is tight around the ankle, so be sure to wear taller socks and exercise a little patience getting into them. This amazing trail shoe is one you've got to try and earns our highest accolades for its balanced performance on all types of terrain.

Large, tapered fit at the toe

The Salomon Supercross Blast follows its predecessor, the Salomon Supercross, in design and performance. Built for comfort and confidence on the trail, it features 5mm ContraGrip rubber lugs that stick to basically everything. This shoe is a top choice for sloppy, wet, or muddy terrain. It also does well on dry or technical trails where ridge traversing or some rock climbing is involved. The continuous nylon upper is ultra-protective with a fit that is surprisingly wide in the forefoot for the Salomon brand. Few others in our lineup have better, more supportive traction, and the price can't be beat.

Unfortunately, the fit of this shoe is very long and tapered. Huge in our opinion. If you're not into having about an extra inch of space at the toe, we recommend sizing down at least a half size. And while we like the ease of use of the single-pull lacing system, the lace sometimes comes unlatched and flops around, which for some can be a deal-breaker. If you're seeking a super comfortable and technical trail runner, this one will stick to the trail, whether it is muddy, slick, or steep.

Great price
Fun and celebratory rainbow design
Comfortable with nice traction
Both wide and regular fit
Doesn't shed mud or small stones well

The Merrell Antora 2 stands out as a versatile trail runner with a traditional design and fun rainbow pattern. During our testing, it did well over snow, wet mud, buffed-out trails, and technical terrain. The outsole is responsive and energetic, propelling you forward with each step. The protective cushioning underfoot and breathable mesh offers traditional trail comfort for both long and short distances. It also comes at a great price.

This shoe scores average across our metrics, earning it a lower position overall, but it is still an overall nice trail runner. It is offered in wide and regular sizes, and while testing the wide version, we felt the toe box was actually "regular" in width. Additionally, the harder underfoot cushioning does take some breaking in time and might be too firm for certain preferences. That said, this is a supportive trail runner that does well across most surfaces (except for very sticky mud). It is an excellent value that we recommend to take you over steep and technical trails while crossing over to the road.

Excellent trail intimacy
Fitted and streamlined performance
Lightweight
Just protective enough for most surfaces
Very sticky and confidence-inspiring outsole
Narrow fit doesn't work for all
Protection doesn't cut it for long mileage without lots of training

The Inov-8 Terraultra G270 is a low-profile and streamlined shoe that hardly feels like it's there. Designed to feel like an extension of your body, it is incredibly lightweight yet still durable. The upper is breathable and quick to dry, with a newly redesigned outsole that's incredibly sticky. It has a zero drop, favoring those with a forefoot strike and without much extra cushioning in the heel. In this shoe, you'll feel intimate on the trails, as it has no rock plate and only 12mm of underfoot cushioning, making it very flexible and agile on the trail. Overall, if you're seeking a sensitive and flexible shoe that is amenable for a forefoot striker, look no further.

Unfortunately, the newest iteration of this shoe has a narrower fit, where the past design offered a wider toe box. While this is amenable to some, others may not like it. Additionally, the size 9 shoes we tested just fit our main tester, without a lot of room for foot swell or toe splay. For extra room, we'd recommend buying a half size up. The underfoot protection lacks a rock plate, which makes the shoe more flexible, but you can definitely feel impacts underfoot. If you're looking for full protection, this shoe doesn't have it. Finally, the price is high. While the shoe is durable, if this isn't the perfect design for you, the upfront cost may not be worth it. Overall, this is best for a forefoot striker seeking a sensitive and streamlined fit that's race-ready for technical and crossover terrain.

Best for Long Distances


Altra Lone Peak 5 - Women's

Weight (per shoe): 9.7 oz | Heel-to-toe drop: 0 mm
Wide forefoot allows for toe spay
Well-cushioned midsole
Foot shaped design
Requires a training period to get used to
Lacks durability

The Altra Lone Peak 5 is a staple shoe in the ultra distance and hiking community for a good reason. It is packed with 25mm of cushioning throughout the length of the midsole, with an extra-wide toe box that mimics the natural splay of the forefoot. The upper offers breathability for hot days, it drains well when wet, and dries quickly after a good dunk in a cool stream. It hosts a 0mm drop, meaning this doesn't have additional support or cushioning in the heel. It is best for those that intend to strike the ground with the forefoot and not the heel. It's our favorite for longer distances and the one we choose when there's a long fast pack or training day ahead.

While we love this shoe, it's not for everybody. The zero-drop design takes a lot of training to get used to. Since there is no extra cushioning in the heel, it pushes you onto your forefoot, which can be tough on both the calves and Achilles. With proper training, this can wane, but it will take time, rolling, and a little physical therapy to get a newbie up to speed. Also, the fit is very difficult to lockdown, and one of our narrow-footed testers had trouble in regards to the foot sliding forward on big descents. One of our biggest gripes with Altra shoes, in general, has been poor durability. Over the last six years, this model (and others) have consistently torn in the upper and packed out after 300 miles (or less). We hope this new update is more durable than the last, but time will tell. We keep buying them because when the performance is good, it's head and shoulders above the rest in comfort. For those seeking a softly cushioned, well-protected, and wide trail shoe that gives you room to spread your toes, look no further.

A cushioned and comfortable ride
Wide landing platform now inspires better stability
Wicking upper that dries quickly
Stack height takes some getting used to

In search of comfort? The Hoka Challenger ATR 6 features an uber plush midsole for hitting the trails for hours on end. Built as a maximalist shoe for long-distance running, it grabs and suctions to most surfaces, doing best over dry buffed-out trails with fewer trail hazards. The streamlined outsole is super breathable and quick to dry, making it a perfect option for river crossings or wet weather. The new foot box is still wide but has a taper at the tip, with a wider fit that still hugs the heel and arch. This wider platform makes the shoe significantly more stable than any other Hoka One One shoe we've tried, competing with other plush contenders in the area of stability. If cushioned comfort is your top priority, you've arrived at the right place.

Given the excellent level of breathability, this shoe is not warm in the winter, nor can the lugs grab super sloppy muddy surfaces. As a result of the responsive cushioning, it's also not very sensitive. While stability is better, it's still not a shoe we would choose for trail-less terrain. If you do venture into these parts and are set on its design, just know it'll take some time to get used to. This is a wonderful option for those that prefer a 5mm drop with ample amounts of cushioning underfoot.

We've hiked up towering passes in Peru, run over summits in the Rocky Mountains, and jogged over dry singletrack in the desert. We've taken on self-supported 50K distances in Iceland and logged training miles on the sunny shores of Hawaii. Our main testing site is the steep trails of Ouray and Silverton, Colorado, home to the Hardrock 100, which offers some of the most beautiful trails you'll find in the USA (in our opinion). Each pair of shoes in our review has logged at least 60 miles — some with over 1000 miles, if they last that long. Our review compiles this data to give you recommendations for your best trail sidekick.

Analysis and Test Results


Our trail running shoe review covers a wide range of products to reflect the best options on the market. Each shoe is subjected to the same tests to objectively determine even tiny differences in performance. After rating each across our metrics, we assign it a comparative score to determine which has the best performance. We compare each in-depth to help you find exactly what you're looking for.

While we tested what seems like a mountain of shoes, there are some obvious winners that we need to gush about.

Value


When buying a pair of shoes, you want to ensure that they will perform well for the money you invest. A good shoe with great value is one that'll last and won't break down after a hundred miles. Many shoes will either lose responsiveness in the foam or lose an upper after this time. However, many folks opt to buy those that are not as durable simply because they are light and flexible with good performance when they are in top shape.


Of the shoes we tested, there are plenty of durable options that offer great performance for a reasonable price. The Saucony Peregrine 11 stands out for its versatile design with an aggressive outsole that'll stick to steep trails and mud. Others in our lineup include the Salomon Supercross Blast, great for softer terrain, and the Merrell Antora 2, which does well on moderately technical trails. The Supercross Blast features longer lugs with more space for better mud shed. The Antora 2 is a more versatile trail runner, scoring lower points overall, but built for crossover terrain in addition to moderately technical surfaces. All of these options are also more durable than others in our testing so far, proving to have responsive midsole construction that doesn't pack out and an upper that's impervious to the elements.

Foot Protection


An excellent trail runner provides the right combination of foot protection to sensitivity, allowing a runner to feel the trail underfoot without suffering hard blows from unsuspected hazards. In this metric, we consider the cushioning and the presence (or not) of a rock plate. We also explore the architecture of the upper to see if it is breathable and keeps out smaller particles from entering the shoe. Finally, we look at the toe cap's rigidity and protection from unsuspected stubbed toes. All the trail running shoes tested offer enough protection to be worn on trails, with some providing more than others.


The most protective shoes are those with lots of underfoot cushioning and a well-constructed upper. Of our selection, the most protective shoes with a thicker outsole include the Hoka Speedgoat 4 and the Hoka Challenger ATR 6, our favorite for cushioned comfort. Neither have a rock plate, but instead sports loads of underfoot cushioning. While Hoka One One doesn't discuss the stack height of their shoes, we measured the Challenger ATR 6 to sit about 25mm off the ground. The Speedgoat 4 has a little extra height. With both, the midsoles swallow up trail hazards, offering a smooth and protective ride. Both have a protective upper that is porous across the mesh, with a breathable architecture.

Other options earned an equally high score. The Salomon Speedcross 5, and Salomon Supercross Blast have a well-cushioned midsole with no rock plate, which maintains flexibility and sensitivity. The Speedcross 5 is a little more protective underfoot, offering 35mm of rigid EVA cushioning in the heel, and 25mm in the forefoot. The Supercross Blast has a little less cushioning, with 29.3mm in the heel, and 19.3mm in the forefoot. Both have a continuous upper that is quite protective with excellent wicking capabilities. The Speedcross 5 is a touch more protective than the Supercross Blast because of this cushioning difference. It also has a more robust toe cap.

While these shoes have beefier outsoles with a larger heel-to-toe drop, there are other protective options with a medium amount of cushioning underfoot. The integration of a rock plate aids a little extra protection. The Altra Lone Peak 5 is a notable shoe in this category, sporting a softer but thick midsole (25mm in the heel and forefoot) that is incredibly protective and well-cushioned, with the addition of a rock plate to counter the softness of the materials. The Topo Ultraventure 2 is a similar contender, boasting a little extra cushioning in the heel (30mm) and 25mm at the forefoot. It has an outsole that is much more rigid than the Lone Peak but doesn't integrate a rock plate. The Scarpa Spin Ultra also falls into this category (without a disclosed stack height), with more responsive foam and the integration of a rock plate. All of these are great options for hammering on either the pavement or trails for ultra-length distances because of the level of comfort.

Other shoes sport minimal cushion but have protective elements that still make them a good choice for technical terrain. The Dynafit Feline SL features an ultra-hard toe cap, similar to the La Sportiva Bushido II. Both have a lower stack height. The Feline SL does not disclose this, but the Bushido II is only 19mm in the heel and 13mm in the forefoot. The Feline SL also has a burlier upper with a single-pull lacing system and isn't as flexible as the Bushido II, thus earning a higher score in this category.

Best for Water Crossings

Seeking the best trail running shoe for crossing the odd stream? A shoe with a waterproof upper that doesn't absorb moisture and dries quickly is the best option. None of the shoes we tested are completely waterproof, but some dry out faster than others. For example, the Hoka Challenger ATR 6, La Sportiva Bushido II, and Inov-8 Terraultra G270 all have an overlay mesh that isn't water-resistant or waterproof but does dry quickly while on the run. We appreciate the Altra Lone Peak 5 and Altra Superior 4.5, which has a dedicated drainage system for quick-drying performance. We also love the Salmon S/Lab Ultra 3 as the upper dries quickly and resists water from penetrating around the outsole if the puddles aren't too deep.

Many of the shoes tested have a "GTX" version, meaning Gore-Tex is used to add water protection. If you know you'll be tackling a lot of water, look for this option - just realize it's likely to be far less breathable and more expensive.

Traction


When treading over slippery and soft terrain, good traction inspires confidence and limits slips and falls. So, we made sure to pay attention to each shoe's ability to bite down on the trail. When testing, we subjected each trail running shoe to different types of surfaces in different conditions; this included mud, snow, pavement, scree, sand, sandstone, granite slabs, and more. The slope we test on ranges from steep and unstable to flat. We also dunk them in rivers and run in the snow to see how each performs when wet.


Through our testing, none of the outsoles were able to perform perfectly on slippery and wet rocks. Some rubbers are stickier than others, but none can completely ensure a slip-free experience when crossing rivers or jumping across boulder fields in the rain. Be careful with a shoe that markets itself to stick to these surfaces.

Three shoes stand out for their traction: the Dynafit Feline SL, Salomon Supercross Blast, and Salomon Speedcross 5. All have longer lugs that'll stick to most surfaces. However, the Speedcross 5 and Feline SL both have more rigid and durable lugs, holding better on steep surfaces that are quite sloppy. We tested this while running with one shoe on each foot. The Feline SL proves to slip less in these conditions comparatively. We could also run with this shoe on the road without worrying about lug wear-down, unlike the Salomon options.

If you plan on tackling trails less littered with grass, mud, and other soft surfaces, you'd be better off looking at shoes with lugs that aren't as long but feature stickier rubber and a nice pattern. The stickiest rubber out there comes with the Salmon S/Lab Ultra 3, La Sportiva Bushido II, Terraultra G270, and the Salomon Sense Ride 4. All have a sticker compound that grips well to rocks. The Hoka One One options also do well in this category with varying traction patterns.

Here we compare a few options that have sticky rubber. The Dyanfit Feline SL (middle) does better than these Salomon options sticking to rocky surfaces and taking on muddy conditions.

Less sticky, but more aggressive outsoles with longer lugs for better purchase on steeper trails include the Saucony Peregrine 11. This high-value shoe sports longer lugs that did well across most of our tests, only really falling short with mud shed. The only shoes that performed in the mud shed tests are those with lugs that are a little further apart, like the Salomon varieties. The Altra Lone Peak 5 also has a more aggressive outsole, but it's not as sticky as others, like the Topo Ultraventure 2 that sports a Vibram sole which is also more durable.

While the choices above are great for more technical terrain, all the shoes scoring mid-range offer functionality on most trails you'd encounter when running. All can take on rocky, dry singletrack easily. Those that are great for both the road and the trail (crossover options) also exist. If you find yourself on the road more often than not, take a look at the Brooks Cascadia 15, Altra Superior 4.5, and Nike Terra Kiger 6 that transition easily from the road to trail. These have less technical outsoles that are still pretty grippy on moderately technical terrain with lugs that won't wear down quickly on pavement.

Sensitivity


Shoes that offer excellent sensitivity have less cushioning underfoot. Sensitivity is important because it allows a runner to feel underfoot hazards, which gives them time to re-adjust body positioning. Sensitivity must be balanced with foot protection to make an excellent shoe. To test this, we noted which shoes are the thinnest and which allowed us to actually feel underfoot hazards.


The most sensitive options come with just a tiny bit of cushioning underfoot, so you can feel the trail as you run. The Salomon S/Lab Ultra 3 is among the most sensitive, with just 18.2mm of dense cushioning in the midfoot. The sole is flexible, which had us feeling most objects underfoot, with a balanced level of protection. Both the Inov-8 Terraultra G270 and La Sportiva Bushido II have very thin outsoles with an added rock plate for protection.

Shoes that are more flexible tend to put into the midsole and are thus more sensitive. Here we compare a few options. Top left: Scarpa Ultra Spin (less sensitive). Top Right: Merrell Antora 2 (moderately sensitive). Bottom: Dynafit Feline SL (left) and Inov-8 Terraultra (right) - both highly sensitive.

The Bushido II is a touch more rigid, but the outsole is incredibly dense. Both offer a very sensitive ride. The Altra Superior 4.5 also scores high in this metric, with a thicker outsole (21mm heel and toe) and a very thin rock plate. While the stack height is higher, the midsole material is incredibly soft, which translates to a similar level of sensitivity on the trail. If intimacy is what you seek, choose any of these options.

Stability


A stable shoe is one that'll keep you on your feet when picking through rough rocks and uneven terrain. The stability of the shoe comes as a proportional value of the height and width of the shoe itself. Those that are lower to the ground, with a more flexible nature and wider outsole, tend to do better here. That said, some shoes are built to be rigid, which flattens uneven terrain underneath them. So while some stable shoes are flexible, others can be rigid. Overall, we look for a shoe that doesn't feel tippy and keeps us upright while tearing down the trails.


Two shoes stand out as among the most stable in our review, for two completely different reasons: the Scarpa Spin Ultra and the Inov-8 Terraultra G270. The Spin Ultra is comparatively a beefier shoe with a more rigid platform and an integrated rock plate. The body of the shoe is rigid, with a wide forefoot and heel that offers an excellent landing pad. The shoe doesn't feel tippy, but light and responsive, earning its high stability score. The Terraultra G270, on the other hand, is incredibly lightweight, low to the ground, and has a narrow profile. It is similar to the Salomon S/Lab Ultra 3. Both are stable because of their incredible flexibility that allows for agile and full movement. All three of these shoes earn the same score for their excellent overall stability, but for different reasons.

We love the stability of the Inov-8 Terraultra G270. We test it on the Bear Creek trail in Ouray. While this section looks nice and easy, the rest is full of rocky shale, which showed us this shoe can perform in off-camber situations.

Other options with a little less cushioning include the La Sportiva Bushido II and Dynafit Feline SL. We aren't sure why the Feline SL shoe feels so stable on the trail, but the fit makes it feel like you aren't sitting very high. The platform width is narrower than the Bushido II, but they both feel close to the ground, without tipping over technical terrain. Both also have a really nice fit, with nice agility. The Bushido II feels a touch more rigid but has a wider toe box for better balance as you move down the trail.

Other options with a wider toe box feel a little more stable than those that are more narrow. For example; the Altra Lone Peak 5 has a higher stack height but an incredible amount of stability for its boaty fit. The Brooks Cascadia 15 is another stable contender with built-in pivot posts that have a more rigid design, inspiring confidence on the trail. We also like the Salomon Supercross Blast that has a longer fit and a very wide landing platform in the forefoot and heel. All are good stable options to consider.

Comfort and Fit


In this metric, we score based on the anatomy of the materials on the collar, the lacing system, and how the cushioning feels on both lift-off and landing. We note relative fit but don't score on it simply because it's such a subjective metric. Ultimately, it's important to consider that the most comfortable shoe is the one that fits you best.


With amazing cushioning throughout the midsole, it's not surprising that the Hoka Speedgoat 4 is the most comfortable shoe we tested. It stands out for its responsive midsole that provides ample protection from underfoot hazards. However, while the Speedgoat offers more springy cushioned bliss (it has a thicker midsole), it's not as light or responsive as the Challenger ATR 6. The Speedgoat 4 also has a narrower toe box with a tapered look towards the toes.

The Challenger ATR 6 has excellent underfoot comfort. While this trail is nicely buffed, it offers a ride that makes you feel like you're stepping on a flat platform all day long.

Other shoes with a taller stack height, like Salomon S/Lab Ultra 3, Salomon Supercross Blast, and Salomon Speedcross 5, don't provide the super springy experience quite like the Speedgoat 4, but they do have responsive cushioning underfoot. Other responsive shoes include the Inov-8 Terraultra G270, La Sportiva Bushido II, and the Dynafit Feline SL.

The Topo Ultraventure 2 and Altra Lone Peak 5 both have a wide toe box that lets your toes wiggle. On longer runs, this is an advantage as feet tend to swell as you put down the miles. Between the two, the Lone Peak 5 has a wider toe (with a wide and regular fit option) while the Ultraventure 2 has a wide toe box at the widest part of the foot, with a more significant taper towards the twos. Those that appreciate toe-wiggling freedom should consider either of these. They both have medium amounts of cushion too, with the Lone Peak 5 having a softer insole that tends to pack out a little faster than the Ultraventure 2.

Fit


In this section, we provide recommendations for relative sizing. Here we focus on the foot width to provide you with a jump-off point for where you need to start looking. We indicate if the shoe you want comes in either a wide or regular fit option.

Narrow Fit

If you have a narrow foot, look for shoes with a tight-fitting heel cup and a narrow profile around the arch. The forefoot can still be wide, but it's important that you can lock your foot into the shoe to avoid slippage. Shoes made by Salomon are a great option for you. We also recommend the Dynafit Feline SL, Inov-8 Terraultra G270, and Nike Air Terra Kiger 6.

Regular Fit

Most shoes fit in this category. A regular fit is one that most people can wear. Of them, the Saucony Peregrine 11, Salomon S/Lab Ultra 3, and Merrell Antora 2 are three of our favorites. Many of the shoes we tested have a regular fit and fall under this category. Many of these shoes have regular and wide-size options too.

Wide Toe Box

Are you looking for a shoe that offers a wider toe box? The shoes by Topo and Altra dominate this market, but there are many other options out there. Our favorites include the Topo Ultraventure 2 and Altra Lone Peak 5. Both are options you should try on and check out if you like more room in the toe box. The Ultraventure has superior durability and a little extra cushion in the heel in comparison to the Lone Peak, but the comfort of the Altra's, we think, can't be beaten.

The Topo Athletic Ultraventure 2 is another option with a wide toe...

Weight


Having a lightweight shoe on the trail can make a world of difference if you're out for the day. If you're an ultra-runner, a couple of ounces may feel like ankle weights after 50 miles. If you're a recreational runner, a lighter construct may allow you to increase your turnover and leave you feeling liberated on the trail. When evaluating the weight, we look at which is the lightest on both the foot and the scale.


All shoes tested in this review are considered "lightweight"; we just provide a comparison of the heaviest to lightest options. None felt too heavy for wear on the trail.


The lightest shoe we tested is the Altra Superior 4.5 (7.9 oz per shoe). Its zero-drop is perfect for anything from long distances to a short training run. Following this are other super lightweight contenders. With its lightweight construction and protective cushioning, the Nike Terra Kiger 6 (only 8.7 oz) feels weightless on the trail. The Inov-8 Terraultra G270 is also pretty amazing, weighing just 8.3 ounces with more protection, better traction, and durability.

Conclusion


We've come a long way from running barefoot. While some still prefer this wild form of running, a great trail running shoe will offer you more comfort and protection from underfoot hazards. The quest for the perfect shoe is always challenging, so be sure to identify what you care about most, try on potential options, then buy the one that fits best. Happy shoe hunting.
