8 reasons to buy

  • Many people commented that the upper unit of the Altra Lone Peak 4.0 was sturdy and secure.
  • The toe box received praise for having a roomy construction that welcomed natural toe-splay.
  • The outsole design of this running shoe was lauded for being helpful with movement over uneven terrains.
  • Most consumers were happy with the longevity of this product’s components; they stated that the elements resisted wear-and-tear while also evoking excellent quality.
  • The midsole unit was appreciated by runners because it was reactive but not flimsy.
  • Most users didn’t notice the weight of this shoe at all; they felt that it was suitably light for all-day use.
  • A majority of those who have tested this shoe claimed that the sizing scheme followed their regular anticipations.
  • The width profiles of the men’s and women’s versions were appreciated because they suitably housed feet that have medium and low volumes.

5 reasons not to buy

  • A few people stated that the lacing system caused the tongue unit to pinch the skin, resulting in hot spots and chafing.
  • Some testers weren’t happy with the design and color schemes; they claimed that the aesthetics looked outdated.
  • A couple of purchasers felt that the sole unit of the Lone Peak 4.0 was a bit heavy.
  • The back end of the collar has a curve that rubbed against the heel irritatingly, several runners complained.
  • The upper seemed like a sponge to a couple of runners; the fabric apparently tended to take in liquid and not let it dry off.

Bottom line

Many people were happy with the Altra Lone Peak 4.0. They were ecstatic because of this trail companion’s durable construction, precise outsole traction capacity, and lightweight build. Yet the part that got the bulk of the praise was the broad design of the forefoot section; people felt that it permitted the foot to relax and assume a natural position during the run. But there were complaints about the irritating upper aspect, as well as the water-magnet of an upper.

The Altra Lone Peak 4.0 is a product meant for trail running enthusiasts and those who have neutral running gaits.

    Altra Lone Peak 4: You have almost everything I need. Almost.

    More photos

    By all accounts, I have a wide foot. It is something I’ve known for years. Sitting in my local REI and perplexed by how the measuring foot thingy worked, the associate comes over and slides the parts around my foot and proclaims: “You are a true wide.”

    And there you have it, folks: I have Fred Flintstone Feet.

     

     

    So, you would have thought that Altras would be a gift from the heavens for me, right? Manna falling from the sky? Well, not quite.

    If you’ve spent any considerable time hanging out with trail runners, you’ll often find yourself in a sea of Altras. Given the die-hard adoption of this brand, I figured I must be missing something good.

    So, I coughed up the full-price of $120 for a pair of Lone Peak 4s. The size seemed right (not too much space at the top). They were super comfy walking around the store and felt unbelievably light (ladies: 8.5 oz, men's: 10.2 oz). I was sold!

    The thing with Altras is that they are zero drop—all models. Generally speaking, I’m not that cool with zero drop shoes, but I figured I could always add a lift under the insole as do quite a few of my Altra-wearing friends.

    I took them for a 4-mile spin on the local Marian Bear trails. They felt fast and plush! It was like I was running around in Cadillacs.

    But, I did notice on that shorter jaunt that my foot did not feel secure and would shift around laterally while taking quick turns and steps over more technical spots.

    Given my calves and shins found that zero drop experience to be a little taxing, I dropped about 6mm of foam lifts I bought off Amazon under the insoles. I found nothing was lost on the fit and security of my heel by doing this.

    So, if heel security is a fear of yours, fear not! No heel slippage with these shoes—even with lifts.

     

    Some of the other features in this shoe that are top-notch

    • Gaiter Support: In my opinion, it’s the best in the market and supports different types of gaiter attachment.

     

     

     

    • Grippy McGripperson outsole

    The lugs are prominent but not stiff, and they don’t seem to wear that quickly. I have a super high cadence (very short legs = 190+ steps per minute at my marathon pace).

     

     

    So, I wear my outsole faster than my taller counterparts. At 50 miles, I see almost no wear, which is rare for me. Traction is excellent on the sand, hard-packed dirt, soft dirt, rock, and asphalt.

    • Super plush and springy for the weight
    • Great flexibility through the forefoot—not at all stiff

     

     

    • Protective rock plate without losing much ground-feel.
    • Material is breathable without letting in lots of dirt and sand
    • I dig the look and colors.

     

    Things that drive me bananas about this shoe

    • Even with a standard double knot, the laces come untied. They are also really long with no laces garage in the tongue.

     

     

    • Sloppiness on anything remotely technical and/or narrow/rutted
    • Even with my aforementioned wide foot, I can’t tighten them enough to feel like my foot is secure. I have pulled the laces as tight as they can go so I’m at a loss what more I can do (and a smaller size would have been too short in length so that would not fix it).

     

    Basically...

    What I have found with these shoes over the last two months is while they have nearly all the features and qualities I want in a trail shoe, they do not work for even moderately technical trails. They are far too sloppy.

    A couple of weeks ago, I ran a 16 miler in these shoes out in a slightly rocky stretch of Cuyamaca State Park.

    At one point, as I was navigating a few rocks and ruts, my foot slid sideways in the shoe, I lost my balance and kicked the inside of my ankle, yelped in pain, and then nearly landed in a bush.

    As far as I can see, if I’m running on a non-technical wider dirt road or super well-groomed trails, this shoe will be fine. But, that is a rare thing here in Southern California, never mind it’s a whole lot less fun.

    Likely, I will hit 200-250 miles in these shoes doing easy 7-milers in them, call it good, and retire them.

    It’s too bad they missed the mark with fit because everything else is fantastic. But, without a sound, secure fit, what’s the point?

    Altra Lone Peak 4: Getting more in touch with nature

    Before getting into the review, it’s worth mentioning a very cliche story that most runners go through at some point!

    I read "Born To Run" and was inspired. I wanted to try a more ‘natural’ running shoe. I didn’t want to go barefoot and thought about making the transition slowly starting with the brand Altra.

     

     

    Altra is known for using a wide toe box and high flexibility to engage the foot better—I was sold!

    The upper

    I have a number of issues with the Altra Lone Peak 4's upper. One is that there are not enough eyelets for the laces that would help to lock the foot in. Moreover, the laces are far too long.

    There are also too many overlays. I have always been a fan of more simple uppers. 

    There are definite durability concerns. The front of the shoe came apart so quickly that Altra swiftly sent me a new pair.

     

     

    The heel and early parts of the midfoot were dialled down nicely. However, the front third of the foot was all over the place.

    I would blame it down to my narrow foot, but given the rest of the shoe is fine, I don’t think this is the issue. On smooth terrain, the problem was less exaggerated.

    However, as soon as you take it on the trails, it’s not an enjoyable experience. My foot would slide everywhere, and I had little confidence at high speeds.

    On a more positive note, despite the wide toe box, there was never any bunching of material even when you tighten the laces heavily.

    The material also worked well in wet conditions, being quite ‘hydrophobic’ but oddly is not being particularly breathable (I was running in Costa Rica, which probably didn’t help).

    The midsole

    The midsole was something I can get behind. Bouncy, soft yet responsive, not thick and very flexible. What more could you want?

    This is the first (and last to date) Altra I have used and was impressed with the midsole. If the shoe was based purely on midsole and outsole, this would be very close to scoring a 10/10.

    It has a lively ride with seemingly good energy return that just makes you want to go fast. It never felt harsh.

    I also never felt the need for more cushioning, even after a two-day hike up Costa Rica’s largest mountain.

    Of course, following Altra’s mantra, the shoe is very flexible. And despite having a history of pronation, this was not a problem and engaged my foot nicely.

    The low drop was very welcomed, fast on flat terrain and great for training. Not much else to mention here, it’s a good midsole that works well.

    The outsole

    The outsole was one of the standout features of the Lone Peak. A very mixed lug pattern meant it was able to handle variable terrain well. They also seemed to hold up well.

    On road, the areas that would wear fastest have wider, less aggressive lugs. These are surrounded by lugs that only come into play when the going gets tough.

    On top of this, the lugs are conformed into a foot shape pattern, meaning they don’t aggravate the foot on smoother terrain, riding similar to a road shoe.

    The conclusion

    The Good: This is perhaps the best outsole I have ever come across. Meanwhile, the midsole is also something truly special.

    The Bad: The fit. Unless your forefoot is hugely bigger than the rest of the foot and you can fill the toe box out properly, this is sloppier than Oliver Twist’s second helping.

    Hopefully, this image shows the beginning of the issue I had with my first pair of Lone Peak’s with the grey pair being the replacement—a really exciting colour, I know.

    The outsole could be slightly lower profile and the upper overlays slimmed down to get there.

  • 95 / 100 | Runner's World | | Level 4 expert

    While the majority of wear-testers praised the Lone Peak 4’s traction, a few runners were impressed with the shoe’s updated upper as well. It’s made of a quick dry air mesh with a built-in toe guard. “The durability seems to be the biggest improvement with this shoe,” said a tester. “In the Lone Peak 3 the toe delaminated quickly from the upper; this has not happened yet after a few hundred miles in the Lone Peak 4.”

Become an expert

  • Altra running shoes are known for the zero-drop platforms and technology-laden builds. They are also recognized for the capacity to welcome the natural shape and motion of the foot. One might say that such characteristics are only applicable to their road options, but they’re also present in their trail running line.  The Lone Peak 4.0 is an example of an off-road runner that’s meant to permit the natural biomechanical capabilities of the foot without sacrificing protection, comfort and outstanding traversal.
  • The upper unit of this product utilizes Quick-Dry Air Mesh. It is supported by stitched-on overlays that also serve as trappings for securing the foot in place. The tongue unit has a webbed surface that aims to cinch against the foot and avert sideward slipping. There are drainage ports at the bottom to remove water from the interior chamber (if water exposure is part of the run).
  • Ethylene vinyl acetate (EVA) and A-Bound™ serve as the primary cushioning system of the Altra Lone Peak 4.0. These elements work together to ensure reactive and resilient support while on the trails. The MaxTrac™ rubber outsole and the StoneGuard™ film are the technologies that handle the rocks and other debris that litter the unpredictable outdoor terrains.

The Altra Lone Peak 4.0 is a bit larger when it comes to size. Runners are encouraged to get a pair that’s half-a-size smaller to achieve a pleasant in-shoe coverage. But trying on the shoe first before purchasing can ease the mind and enervate any concerns about a shoe that won’t acclimatize well to the outline of the foot.

Widthwise, the available options are D – Medium and B – Medium for men and women, respectively. Those who have low or medium foot volumes are the ones who are likely to welcome the in-shoe experience.

The semi-curved shape of this product, as well as the foot-shaped construction of the silhouette, welcomes the inherent curvature of the human foot.

The outsole unit of the Altra Lone Peak 4.0 is made up of the MaxTrac™ technology, a compound that is durable and able to withstand the damaging nature of the surfaces. This layer is also constructed to provide surface adherence, a property that is highly essential when traversing uneven topography.

Curved gripping lugs form the TrailClaw™ configuration. These prominent nodes act like hooks that clamp onto the ground, thus delivering heightened grip. The opposite-facing layout enables foot-to-ground control during upward and downward traversals.

The trail rudder is fundamentally an extended outsole structure. The extra length permits additional surface control, especially when handling descents.

The A-Bound™ technology is a full-length topsole that’s designed to provide robust cushioning to the underfoot of the wearer. The material itself is made using environmentally friendly materials to reduce material wastage and buildup of plastics.

Ethylene vinyl acetate (EVA) is an industry-standard compound that’s used for many running shoes. This piece acts as the midsole foundation, supporting the top layer and the foot at the same time. It doesn’t sag quickly or lose structure after each run.

The StoneGuard™ technology is a sheet of thermoplastic polyurethane (TPU) that is sandwiched between the midsole and outsole. The job of this layer is to protect the foot from the abrasive elements on the trails. It’s robust but flexible enough to follow the natural movement capacity of the foot as it bends and gears itself for each step.

Additional cushioning is provided by the 5-mm contour footbed. This extra piece can be removed or replaced with a custom orthotic insert if the wearer chooses it.

The upper unit of the Altra Lone Peak 4.0 is made up of the Quick-Dry Air Mesh. This fabric offers breathability and security without luring in trail debris. Ventilation holes are present in this material, but they’re not prominent. The Quick-Dry distinction means that it’s made to stave off water absorption and retention.

The Heel Claw construction involves the curved collar design that’s supposed to clamp the back of the foot and keep it in place. The padding that graces the shoe’s rear also helps when it comes to preventing accidental shoe removals and in-shoe wobbling.

The stitched-on overlays of the Lone Peak 4.0 are meant to shield the mesh from scratches and potential cuts. They’re also intended to help the traditional lacing system when it comes to adjusting the tightness or looseness of the fit.

The 4-Point Gaiter Trap is comprised of several overlays on the upper unit that are made to be anchors for separately-purchased gaiter attachments. The four spots that welcome the hooks of the gaiters ensure optimal coverage, thereby protecting the foot from the elements.

The heel-to-toe drop of a running shoe determines the level of heel cushioning and the slanting position of the foot with regards to forward-propulsion and efficacy of the motion. A higher heel profile would mean that the platform is always geared for the toe-off while also focusing more on the support given to the back of the foot.

But running shoes that have low drops mean that a close-to-even plane is available for the foot; natural motion and surface steadiness is encouraged. A low heel-to-toe differential doesn’t mean a thin midsole, though there are options that put an emphasis on proprioception.

Here are examples of shoe families that embody low heel-to-toe drops:

Hoka One One Speedgoat

Hoka One One is a company takes pride in crafting running shoes that have thick midsoles. The Speedgoat series is an example of the brand’s commitment to delivering max cushioning to those who like to take to the trails. The moniker is inspired by Karl Meltzer, one of the most prolific ultrarunners in the world. The Speedgoat shoes that have seen the light of day were also made in collaboration with ‘Speedgoat Karl’ himself.

Trail running requires a shoe’s midsole to have a low (or even zero) drop to adapt well to the uneven terrains. Speedgoat Karl desired freedom of movement and max support at the same time, so the 4-millimeter drop became a sweet spot for a near-even-plane underfoot experience of the products that bore his nickname.

The Speedgoat 3 and its predecessors, the OG Speedgoat model and the Speedgoat 2 are examples of this popular line.

Merrell Trail Glove

Merrell is a company that offers trail running shoes that emphasize proprioception (or the perception of the ground beneath the foot) while also ensuring protection against the abrasive nature of the outdoor topography. The Trail Glove series is the embodiment of a vision of excellent surface adhesion in a flexible package. The name itself aims to point out the importance of a glove-like fit that doesn’t mar the inherent speed and movement capacity of the foot, especially since its sole unit is not substantial in thickness.

Like the Lone Peak 4.0, shoes like the Merrell Trail Glove 5 and its antecedents have a zero drop platform that permits the anatomical positioning of the foot relative to the being on a flat plane.

Topo Athletic MT-2

Topo Athletic strives to be a company that provides products that are fashion-forward yet also highly efficient. They don’t have a lot of models in their roster, but the present ones are made with strict compliance to in-brand quality standards and universal expectations for excellence.

The Topo Athletic MT and its brother, the Topo Athletic MT-2 are products of a design philosophy that involved a straightforward use of industry-standard components like EVA and lightweight mesh, as well as modern shoe-tweaks like a seamless design and the use of printed overlays. The 3-mm drop embodies the near-even heel and toe heights and the push for movement control and natural traversal techniques.
