Hunting for the best pair of trail running shoes for men? We've tested over 90 different pairs of shoes out on the trails in the past eight years, and this 2020 review features 18 of the most popular and highest performing trail runners available today. Our shoe testing program has our expert runners hammering out hundreds of miles each season on forested single track, through desert cactus and slickrock, and usually tagging more than a few summits (40 this past summer and fall!). We follow up with heaps of side-by-side testing, which compares each shoe on a variety of terrain, such as steep dirt, mud, and talus, to figure out how they compare for traction, underfoot protection, stability, and sensitivity. Besides pointing out the best overall shoes, we've also made recommendations for a variety of individual needs and desires.Related: Best Women's Trail Running Shoes of 2020

Best Overall Trail Running Shoe
Salomon S/Lab Ultra 2
The Salomon S/Lab Ultra 3 is out (released early fall 2020)! We've ordered a pair and have commenced testing, but want to be sure we do a thorough job before publishing our findings. Check back soon for an update to this review. In the meantime, the S/Lab Ultra 2 can be found on closeout for a pretty fair price compared to the original MSRP, so if these great shoes interest you, get some now before they are gone. The S/Lab Ultra 2 is the signature shoe of Francois D'Haene, the most badass mountain 100-mile runner in the world (yes, he's beat Kilian Jornet in the last few hundreds they toed the line together). It combines an amazingly protective polyurethane injected upper mesh with a dense, high-mileage EnergyCell EVA midsole to keep your foot protected better than nearly any we've tested, a top priority for torturous and technical 100 milers. It also fits like a glove, and scrambles over rocks as well as the best sticky rubber offerings from La Sportiva.
The biggest downside to this shoe is the exorbitant price tag. We believe that you are getting what you pay for but concede that this is a lot of money to pay for a temporary piece of equipment. Also, runners with wide feet may find the forefoot a bit too restrictive. If this sounds like you, try checking out another very protective offering, with a much wider toe-box — the Scarpa Spin Ultra. Plus, biomechanics nerds may not be thrilled with the 8mm heel-toe drop. Salomon calls this a "racing only" shoe, but we found it far more durable than their other racing-only offerings such as the Sense line of shoes (which are equally expensive). We enjoy wearing it as a daily trainer, and have used it on a whole bunch of scrambling mountain ascents that we often call "runs." If you appreciate the most fine-tuned engineering regardless of price, check out the S/Lab Ultra 2.

Best Zero Drop Trail Runner
Inov-8 Terraultra G 270
The Inov-8 TerraUltra G 270 is the newest, improved version of the older TerraUltra G 260, which was the first shoe in the world to feature the Graphene Grip sole rubber compound. These shoes are far and away our favorite zero drop trail runners, far out-performing the numerous models made by Altra, Merrell, and Topo that we have repeatedly compared them against. They are light, comfortable, very stable, have plenty of protection for running ultra distances, and hold up very well to the test of time. But the best thing about these shoes is the Graphene Grip rubber, which has been tweaked to be much stickier. Graphene has been proven in a lab to be the strongest substance ever tested by man, and Inov-8 was the first to incorporate it into their shoe rubber to drastically improve strength and especially durability. We've run in G-grip shoes for three years and are certainly convinced the rubber last longer. That said, it hasn't always been very sticky, often even feeling slippery to the touch. Change that thought, cause the newly tweaked G-grip now feels on par with the stickiest Salomon Contagrip, and sticks fantastic on rock. These have become some of our favorite scrambling shoes and are a go-to for technical, rocky runs.
Since they are some of the highest performing shoes in our review, we have almost no complaints. A tiny crease at the bottom of the tongue on one of the shoes rubs occasionally, although we've never had it manifest in longterm discomfort or a blister. While they are a pricey choice, we've found that these shoes feel and look practically new after over 150 miles of rugged mountain running, suggesting they are a far better value than some notoriously short-lived alternatives. Honestly, our biggest problems were incredibly tight calves as these shoes repeatedly coerced us into longer runs than we can handle in zero drop shoes. Regardless of whether you only run zero drop, or whether you just want a pair to add to the rotation, the TerraUltra G 270 are certainly the first ones to try.

Best Affordable Zero Drop Option
Altra Superior 4.5
It's becoming harder and harder to find a "low-priced" pair of trail running shoes these days. The Altra Superior 4.5 have retained the same price point that they had about five years ago, and have continued to improve over time. These are our favorite Altra shoes, a brand with a cult following, and we especially love how they have retained their true foot-splaying shape over time as many other models have gotten smaller, narrower, and heavier. We love how comfortable these shoes are, and often find ourselves wearing them around during our daily lives, not only when we head out for a run. On the trails, they are so light and intimate that we find they offer a refreshing take on the daily run, one that simultaneously feels freeing and requires a shorter, more deliberate and considered cadence.
These shoes are very light on protection, and our feet will let us know if we have pushed it too far with the Superiors on. That said, from our perspective, they are the only Altras that still feel like the minimalist, zero-drop shoes we first fell in love with nearly 10 years ago, and haven't morphed into heavier, tighter, clunkier replacements. While they are one of our favorite shoes and come at a relatively low price, they are zero drop, so may take a lot of getting used to for those who are used to higher drop shoes.

Salomon Speedcross 5
The Salomon Speedcross 5 has long been known for its insanely aggressive outsole, a feature that forced almost every competing shoe brand to imitate it. Salomon has improved this by making the rubber on the sole even stickier so that it acts like glue to rock and even wet rock. More significantly, they widened the forefoot of this notoriously narrow shoe by a significant margin. This increased both comfort and wearability for those without narrow feet, while adding to stability with a larger landing platform. These changes, in addition to making the arrow-shaped lugs larger and farther apart for easier mud shedding, and increasing the durability of the already beefy upper, make this the best version of the Speedcross in at least the last six years. The shoe still fits like a glove, with the foot securely locked in place with Salomon's quick lace system; it feels supremely comfortable right out of the box. We've been running in these shoes for more than eight years now and saw our love for them diminish as they got narrower and tighter as time went on. Well, this newest version has won us back over.
This is a shoe that we once again love to run in, but it still has some features that seem a bit outdated. Our biggest gripe is the 10mm heel-toe drop, combined with the very thick and high-off-the-ground heel counter. It's not only unstable, especially when running downhill, but a bit of a relic of a bygone era in shoe design. It's also pretty heavy on the spectrum of ever-lighter trail shoes these days, and it retains its reputation for running a bit warm and short on breathability. This means these shoes are better used for higher altitude mountain runs where the air is cool. While a lot of other companies have put serious effort into improving the traction on their shoes, our side-by-side testing shows that the Speedcross simply grips the best. If you enjoy running off-trail or in the mountains where the ground is often wet, snowy, muddy, rocky, and steep, the Speedcross 5 is an ideal choice, with traction unrivaled by any other shoe.

Best for Maximum Cushioning
HOKA Speedgoat 4
In just over a decade, maximally cushioned Hoka One One shoes have gone from laughably silly to completely normal and mainstream. These shoes offer significant advantages over regular trail runners in the form of drastically increased underfoot protection due to the huge amount of midsole EVA foam cushioning, and also greatly increased shock absorption. Our favorite Maximally Cushioned shoe for trail running is the Hoka Speedgoat 4, the newest version of the shoes designed by Karl Meltzer, the "Speedgoat." These shoes improve on the already fantastic previous version by widening the toe box slightly, and offering a wide EE shoe for those who simply can't squeeze their feet into a regular width. The underfoot foam compound has been changed slightly to purportedly be a bit more springy, although our testers had a hard time telling the difference when wearing one new shoe and one Speedgoat 3 on comparative runs. The Vibram Megagrip outsole offers fantastic traction, on all types of terrain, and is, without doubt, the grippiest outsole on any of the many Hoka shoes that we have tested over the years.
While the positives far outweigh the negatives, we will still point out that we are slightly disappointed that this shoe gained about half an ounce of weight, per shoe, compared to the last version. And while we like the new durable mesh upper material that feels thinner, lighter, and simultaneously more burly than what we have become used to, our water bucket test also revealed that it absorbs more water than the last version, and doesn't shed it as quickly. Due to their increased shock absorption, Hokas have become the most popular shoe for ultra races, and with good reason. We also love how they allow us to bomb down steep hills with a bit more impunity than your average trail runners, and acknowledge that as we age and our bodies lose some of their natural built-in cushioning, the appeal of Hokas continues to grow. Runners who fit into any of the above categories should consider Hokas as a viable choice, and for trail running, look no further than the Speedgoat 4.

Best Lightweight Trail Shoe
Nike Air Zoom Terra Kiger 6
Do you enjoy running on trails, but don't like to plod along in some behemoth of a shoe, sacrificing speed for a stiff, unresponsive ride? Then we highly recommend checking out the Nike Terra Kiger 6, our favorite lightweight shoe for running fast. We've long been in love with the Terra Kiger line, and find that the newest iteration of this shoe is just as fun and enjoyable to run in as all of the others we've tested over the years. This shoe feels light on the foot, offering a nimble flexibility that allows for dancing over rocks and bounding down smooth single track. It's also great for keeping the cadence high, while providing solid traction on dry surfaces. Perhaps best of all, this shoe is stable and sensitive, but can handle long distances with ease.
We've put at least 10 solid trail runs in these shoes, while also alternating them with other competitors, and find them to be one of the most fun shoes for running in daily. Despite claims of a forefoot rockplate, they are a bit light on underfoot protection, so don't gobble up miles of talus or endless boulderfields as well as more cushioned alternatives. They also aren't super great in wet or slippery conditions; their sticky outsole rubber shines much better when the surfaces remain dry. Depending on what color schemes you choose (we opted for the clown colors), these shoes are bright in a way that will certainly get you noticed, but which also quickly stain brown after a couple runs. The Terra Kigers are only minimally changed from the previous version, and are the best shoes you can choose if running light and fast equals more fun.

Best Crossover Shoe
Salomon Sense Ride 3
A lot of people get into trail running from a road running background, and even for those who have been trail running for a long time, it's not uncommon to pump out a fair portion of the miles on the roads. Enter the crossover shoe, designed to be equally at home on the roads or the trails. If this sounds like the kind of shoe that you are in the market for, then let us recommend the Salomon Sense Ride 3, and exceedingly comfortable trail shoe that is more than capable of also splitting time on the roads. What really sets it apart from the competition is the comfort level. "Ride" along on the dual-level Optivibe foam midsole that really allows one to pound the pavement, even if you are a heel striker. The mesh upper is far wider and more accommodating than we have become used to when wearing Salomon shoes, ensuring that this shoe will appeal to far more than only a narrow-footed audience. Combine this comfort with a very sticky Contagrip rubber outsole, and you have a shoe surprisingly capable across all disciplines.
Like many Salomon shoes, this one is a tad heavy compared to other industry counterparts, but in all honesty isn't out of line with many other shoes in this review. We also noticed that due to the relatively high stack height combined with an obvious heel counter — a boon for heel strikers — this shoe isn't super stable on off-camber terrain. If you know the trail you are embarking on is rutted out, or you have a huge side-hill traverse in your future, you may be regretting it in this shoe. That said, we enjoyed this shoe for ultra-distance training runs, where the soft cushioning helped keep our feet feeling fresh. If you like running long distances on any type of terrain, including a helping of roads, these shoes are some that you should check out.

Why You Should Trust Us
This review is led by Andy Wellman, a senior reviewer at OutdoorGearLab who has been testing running shoes since 2014. As a young boy growing up in Colorado, Andy's parents took him for a hike up the popular 14er, Quandary Peak. After huffing and puffing to the summit, he remembers being blown away by seeing a man running down the mountain. Andy soon gave chase, picked up a few pointers from the nice man along the way, and has been a trail runner ever since. He has participated in trail races all over the world, and for a period of time even lived as a nomadic dirt bag so that he could run in the mountains each day. Some of his most memorable runs have taken place in the Himalayas of Nepal, the Pyrenees of Spain, and in the Grand Canyon, but his favorite places to run are the mountain ranges of southern Colorado.
Testing of trail running shoes never really ends, as companies now release new models all throughout the calendar year. These shoes are tested in all seasons, on road trips all over the country, and are continuously compared against the other newest shoes available, as well as against previous versions of the same shoe (you should see all the shoes in Andy's closet). As a bit of a Luddite, he doesn't wear a watch or log his miles and time spent running, but has run in and tested over 80 different pairs of trail running shoes over the past eight years, so feels he has a pretty informed idea about what works and what doesn't out on the trail. That said, since it can sometimes be hard to find people with the same size foot to help him test shoes, he also chats with pretty much every runner he meets to get their opinions of the shoes on their feet. You can rest assured that what you read in this review is knowledge hard-won through time actually spent out on the trail.

Analysis and Test Results
We judge trail running shoes based upon six different metrics: foot protection, traction, stability, comfort, weight, and sensitivity. Why each metric is important for shoe performance, how we test for the metric, and which shoes perform best for that criteria are some of the things discussed below. Keep in mind that all ratings and comparisons are made in relation to the other products tested and a shoe with a low score can still be a great shoe. We recommend identifying what aspects of a shoe's performance matter most to you, in order to zero in on the best choices for your needs.
A significant consideration when selecting a pair of trail running shoes is the value of the purchase. While one could simply assume that you get what you pay for, years of testing has proven to us that this isn't always the case.
When considering the value of a trail running shoe, three aspects are important to consider: price, performance, and longevity. Two of these, price and performance, are easily quantifiable and can be compared effectively.
The third aspect of value for a trail running shoe is longevity, something that is not at all easy to quantify. Since all pairs of shoes wear out and need to be replaced, finding shoes that can withstand more miles of abuse before disintegrating helps ascertain that shoe's value. Unfortunately, not only does every runner put a different amount of strain on their shoes, but we don't have the time or energy to completely trash every pair of shoes before publishing our findings.
In our opinion, the most important criteria for evaluating a trail running shoe is how well it protects your foot. After all, if it doesn't offer your foot protection, why would you be wearing it? The largest component of protection is what is found underfoot — in short, the combination of the outsole and midsole. The soles of the feet are among the most sensitive areas of your body, so if you intend to run on rocky and uneven terrain, which is what we do when we trail run, then your shoe will need adequate underfoot protection. Forego this protection, and watch how your feet will dictate to you whether you can run on a trail or not, and how fast you can go.
Most underfoot protection comes in one of two forms: a rock plate made of a plastic or composite material that adds rigidity to the shoe and absorbs impacts, or in lieu of that, thick foam cushioning. The most common type of foam used is EVA, which not only protects the foot from protrusions but also absorbs a significant amount of the impact inherent to running before it travels upward into a runner's body. The third method of underfoot protection, found on the Nike shoes in this review, is trapped air pockets in the heel that also offer both protection and cushioning. Interestingly, foot protection often comes at the expense of sensitivity, and vice versa, which is why we grade for both.
A lesser component of foot protection is how well the upper does in protecting the top and sides of your feet from protrusions like sticks or abrasion by rocks. The ends of the toes are a common point of abuse, as we have all accidentally kicked a rock while bombing down the trail. Rigid toe bumpers go a long way in helping to alleviate this pain, as does choosing a shoe that is not too tight on the toes. Many manufacturers skimp on upper materials to save weight and offer greater breathability and water drainage, while some have uppers that are as mighty as a Kevlar bulletproof vest.
There are a handful of shoes that offer foot protection that is better than the rest. The Salomon S/Lab Ultra 2 does a great job of protecting the undersides of our feet with its dual-density EVA foam, while also providing far more upper protection than any other shoe we tested. The combination left us smiling, and ensured we could run down a trail as out of control as we wanted, knowing that our shoes had our feet covered. Another shoe that doesn't skimp on protection is the Hoka Speedgoat 4. This shoe, as well as the other Hokas we have tested, has foam that's denser and more absorptive than we would expect. The Scarpa Spin Ultra and Nike Wildhorse 6 also offer an exemplary amount of foot protection. Since we think this is such a vital component, we weighted foot protection as 30% of a shoe's final score.
If it weren't for the drastically increased performance when it comes to traction, there would be only a minimal amount of incentive to purchase trail running shoes instead of road running shoes. Based on this assessment, one could certainly make the argument that traction is the single most important aspect of a trail running shoe, and is certainly one of the very first things you should check out when trying on a new pair of trail shoes.
Two main factors contribute to a shoe's ability to grip a variety of surfaces well: the type and spacing of lugs, and the performance of the rubber used. In general, deeper, more aggressive lugs will grip most surfaces better, especially steep dirt, grass, mud, and snow. More and more trail running shoes are reflecting this with the aggressiveness of lugs growing across the board in recent years. Lugs that are spaced closely together tend to do a better job of gripping well on rock and hard dirt surfaces, while lugs that are further apart tend to do the best job of shedding mud without allowing it to build up into a huge, heavy pancake on the bottom of the shoe.
The hardness of rubber also plays a large part in the traction performance of a shoe. Softer rubber tends to be stickier and does a far better job gripping rock, both wet and dry. The downside of soft rubber is that it wears out, or in some cases rips off, often shortening the life of the shoe. In contrast, firmer rubber tends to be more durable and last longer but doesn't stick to rock nearly as well. Firm rubber is preferable for shoes that will mostly be used on firm surfaces, like hard-packed dirt trails.
While all of the shoes we test offer pretty solid traction, especially on your standard dirt trail, a few are particularly noteworthy for their excellent grip. The Salomon Speedcross 5 has gigantic protruding rubber lugs spaced far apart for the absolute best grip on mud, grass, and snow. It is also the stickiest of any we tested on rock and wet rock, although the lugs have a propensity for wearing down quickly if used too often on hard surfaces. The new and improved graphene infused G-grip rubber found on the bottoms of the Inov-8 TerraaUltra G 270 and Roclite G 290 is also impressively sticky on rock, and is extremely durable. In fact, with the addition of graphene, the strongest textile substance ever lab tested by man, these shoes have the most durable outsoles of any we tested, adding significantly to their value.
Trail running takes place over uneven ground, and being able to land and push off from a stable platform is a critical feature of how well a shoe performs. Failure to maintain stability through the running stride will lead to either losing traction and slipping, or even worse, rolling an ankle, potentially leading to injury.
Through our extensive testing over many years, we have found that stability is largely impacted by the following four factors: stack height, heel-toe drop, landing platform, and fit of the upper. The stack height represents how much material rests between the ground and your foot, and is measured in millimeters. In most cases, the larger the stack height, the greater the chance for a rolled ankle, although this threat can be mitigated by having a wider landing platform. The landing platform is the shape of the bottom of the shoe. Wider typically ensures greater stability, while a narrower platform is less stable. Heel-toe drop measures the difference in stack height between the heel and the toes, once again measured in millimeters.
Over the last many years, shoe companies, largely in response to customer demand, have been slowly lowering the average heel-toe drop, which today rests around 4-8 mm. Shoes with a substantial drop are considerably less stable on uneven terrain, especially going downhill. Shoes with 0mm of drop, known as zero-drop, are usually the most stable. Finally, a shoe with an upper that holds your foot firmly in place allows you to land squarely on top of the footbed, minimizing foot movement within the shoe. The opposite of this is sloppy shoes that don't hold the foot in place through the stride, which are inherently less stable.
Another key factor when considering foot stability is the firmness of the midsole under your foot. Very stiff shoes tend to be more stable than very soft and pliable ones. A flexible shoe that can easily bend in any direction is more sensitive and allows your foot to take the shape of what it lands upon, but this is not generally the most stable design. We have accustomed ourselves to walking on flat, even surfaces, and so a shoe that provides this for you, especially if you are stepping on a very uneven surface like rocks, feels more stable. Of course, stiffness leads to a clunkier feel, which isn't nearly as sensitive and tends to be a bit heavier, so there are trade-offs, and personal preference plays a roll in what will feel better for you.
Most of our testing for stability is done while out on trail or adventure runs, but we also compare shoes in a more controlled setting by running in each of them one after the other both across a steep hillside and straight down a similarly steep slope. Despite having a 4mm heel-toe drop, the Nike Terra Kiger 6 is one of the most stable shoes when running on varied terrain. This is due to the wide toe box and forefoot area of the shoe and the very low to the ground ride. The Scarpa Spin Ultra scored similarly well in our head-to-head stability testing. Of course, the zero-drop Inov-8 TerraUltra G 270 was not surprisingly a high scorer as well. As a critical component of a trail running shoe's performance, but not the most important, we assign stability 15% of a shoe's final score.
Comfort is probably the single most important criteria when it comes to selecting a running shoe, or any footwear at all for that matter, and is what we recommend you value above all other factors when selecting a pair of shoes for you. However, it is also the criteria most difficult to rate - because it is so subjective. Everyone's foot is different, so what feels amazing to one person could be un-wearable by another. Some products are wide in the toe box while narrow in the heel, and some are just really narrow (or wide) throughout. Some fit perfectly "to size," while others run slightly long or short. Since the comfort level of each shoe will be different for each person, we only to rate it 15% of a product's final score.
Craftsmanship plays a large role in how comfortable a given model is. The most comfortable pairs use a seamless construction that makes them easy to wear sockless (although we don't commonly do so, except for comparison testing). Poorly sewn seams or out of place material overlaps inside a shoe tend to rub and wear against the foot over long distances, significantly decreasing their overall comfort. Likewise, shoes that don't do a good job of naturally holding the foot in place mean that we need to crank down the laces to provide a secure fit, often leading to discomfort along the top of our feet or front of the ankle joint over long distances.
Some shoes don't breathe very well and leave our feet excessively hot and sweaty, while others are a bit too short for the size, meaning our toes will hit the front of the shoe, especially while running downhill. Most of our findings for the Comfort metric are based on our anecdotal evidence from long runs on a variety of terrain. We are also sure to run through streams and rivers with our shoes on, in order to get an idea of how much water they absorb, and how quickly they are able to shed that water afterwards. While some people don't mind taking the time to sit down and remove their shoes and socks before fording a stream, in mountain races nobody does so, and depending on the location of your trail running, it may be impractical to take our shoes off as many as 10 times in one day. We prefer to simply let our shoes get wet, cross the creek quickly, and then hopefully the shoes will dry quickly as well.
The shoes with the most comfortable and plush padding are often the ones that feel the most comfortable to us right out of the box. The Scarpa Spin Ultra and the Salomon Sense Ride 3 are two such shoes. The newest version of a longtime, low-to-the-ground favorite — the Nike Terra Kiger 6 — is another top contender when it comes to comfort, as is the Altra Superior 4.5. Many other shoes featured in this review are also exceedingly comfortable, but we acknowledge that it is nearly impossible to eliminate user bias when assessing for comfort. With that in mind, we still strongly recommend you try shoes on before committing to a purchase. If you decide to order online, do so from a company that will allow you to return them if they don't fit as well as you had hoped.
If you peruse this site much you will notice that we love to use weight as a grading metric. One of the reasons is that it's so easily quantifiable and provides a very simple mathematical tool for comparison. But the far more important reason is that all of life, and virtually every outdoor sport, is a battle against gravity, and the less weight we have encumbering us, the more free we are to move around, which makes our sports more fun. When running, we repetitively pick our feet up in order to move them forward, so how heavy the shoes on our feet are does matter. This fact is perhaps best summed up by the old backpacking adage: "A pound on the feet equals five on the back."
An ounce or three of weight difference might not seem like much, but if you consider the fact that you will lift that weight on your foot every time you stride, that means you could be lifting literally thousands of pounds of weight with your feet on even an average length run, which clearly plays a role in accumulating muscle fatigue. Running uphill or for ultra distances only multiplies the potential advantages to be gained from lightweight shoes.
However, when it comes to trail running shoes, features that are added onto a shoe that contribute to a higher weight sometimes also contribute to better performance. For instance, thicker and burlier midsoles with rockplates are heavier, but also protect the feet a lot better. Same with upper materials, and even the amount of rubber lugs on the outsole. Cut out too much of this protection and you will surely end up with a super light shoe, but will also have to moderate your speed significantly to avoid damaging your feet. The takeaway is that lighter is better, but only if it doesn't compromise protection. The shoes described here naturally fall within a spectrum when considering these two factors, and which end of the spectrum is ideal is up to you. With this in mind, we only factor weight as 10% of a product's final score.
The Merrell Bare Access XTR is currently the lightest shoe at a mere 18.2 ounces per pair for size 11, but naturally provides minimal underfoot cushioning, and an enlightening amount of trail feel. The Altra Superior 4.5, weighing in at only 18.6 ounces, is a very close second. Some of the other lightest options come from Inov-8 in the form of their TerraUltra G 270, where the numbers in the name is meant to represent grams of weight, and translated into ounces basically means, "quite light!"
We define sensitivity by how easy it is to feel the trail beneath your feet. While trail running shoes are designed to protect your feet from abrasion, direct blows from the pointy sides of rocks, or from repeated impacts inherent in the motion of running itself, they need to balance this protection with the fact that to run effectively, our brains demand feedback from our feet. The shoes that allow for greater feedback are awarded more points for sensitivity.
The soles of the feet are one of the most sensitive areas of our entire body, which makes intuitive sense if you consider how much it hurts to cut your foot, or how inordinately ticklish many people's feet are. Much like our hands, our feet evolved to be super sensitive because they are one of our primary sources of interaction with the world. In the ages before humans started wearing shoes, the feet were a critical link, via the sense of touch, with the world that we lived in. Honoring this evolutionary history, many runners have found that not only are they better runners when the sensitive link between the feet and ground is maintained, but also more satisfied runners. Perhaps the primal activity of running touches the heart a bit deeper when our ancestral connections to the earth are, even minimally, maintained.
Unquestionably, we now run differently than we did in the past or would be if we had no shoes on our feet. The fact that running is largely competitive, either with others or ourselves, means that we demand more protection to be able to run faster and further, and are willing to sacrifice sensitivity as a trade-off. Since trail running shoe designs tend to reflect this, we weight sensitivity as only 10% of a shoe's overall score, while foot protection is weighted as 30%. However, we test these two metrics pretty much the same way, by repeatedly running back and forth over the most jagged patches of rocks we can find, and noticing the relative differences in the how our feet feel in different shoes.
One pair of shoes stands above the rest when it comes to sensitivity. The Saucony Peregrine 10 is a longtime favorite that continues to get more sensitive over time. While it has an integrated woven rockplate in the midsole that is visible through the rubber outsole, the fact is that it affords more trail feel than just about any other shoe. We enjoy these shoes on shorter runs where we can appreciate the feel of the trail without exhausting our feet, and usually avoid wearing them if we know the going will be rocky. A number of other lightweight options, such as the Nike Terra Kiger 6 or Merrell Bare Access XTRare worth checking out for runners who highly value the feel of the trail.
Running on trails is an excellent way to stay fit and healthy, and has just as many benefits for the mind as it does for the body. We love it because of the incredible variety, the connection to nature, and most of all because of the potential for adventure. There are lots of different styles and types of trail running shoes, many of which are designed for specific purposes. We hope this article has helped you with your decision making process, and that you end up with a pair of shoes that you are not only happy with, but that can be a partner on the memorable adventures to come.
