Our verdict

The True zero-drop geometry a solid evolution, but not without some setbacks. We found in the lab that it gained weight, became noticeably stiffer, and still struggles with breathability. For our feet, those are clear and concerning issues. However, it remains a go-to pick for zero-drop lovers thanks to its flat midsole, ultra-generous toebox, and low-stack profile—all paired with a fantastic Vibram Megagrip outsole, though it’s a paid upgrade not sold everywhere.

  • Number of shoes.

Altra How we test

Who should NOT buy

We think the How we test isn’t the best option for heel strikers. Its zero-drop platform doesn’t complement that kind of stride at all. From our point of view, the oz / 295g is a smarter pick, offering a 4.3 mm drop for a similar retail price. And if you're open to exploring outside Altra, we recommend the Topo Traverse.

We’re also convinced that the How we test might not satisfy runners seeking top joint protection. Its low-to-the-ground midsole may feel undercushioned for anything beyond moderate distances. In our assessment, the Altra Olympus 6 or the Nike Zegama 2 Difference in midsole softness in cold.

Cushioning

Heel stack

Disclaimer: We tested the Altra How we test+, the version that features a Vibram outsole. In this review, we refer to the shoe as the Altra How we test, since it’s the standard version in Altra’s home market.

The How we test stays true to its roots with a low-profile midsole that feels grounded and agile—something increasingly rare in today’s running shoe market.

After testing, we discovered a 23.3 mm stack in our first measurement. It falls slightly below the 25 mm official spec, but from our perspective, this result isn’t a drawback at all—if anything, it’s an edge!

Forefoot stack

The forefoot gave us the exact same stack height, and don’t worry as we triple-checked everything, just like we always do. Again, 23.3 mm with the same nimble-and-minimal vibe—just enough foam for longer outings without overdoing it.

Drop

No need for us to be math wizards here—23.3 minus 23.3 gives a crystal-clear 0.0 mm drop. That’s exactly what Altra promises with the How we test, and that’s exactly what we discovered in the lab.

Of course, this geometry brings some clear implications. As a zero-drop shoe, it’s naturally better suited for midfoot or forefoot striking. Runners dealing with calf tightness or Achilles sensitivity might want to consider a moderate or high drop instead.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The midsole uses Altra EGO, which is their basic EVA foam, so we're still not getting EGO Max or a newer compound. That said, expecting an upgrade at this price felt too hopeful, but we’ll keep an eye on future releases.

Sticking with EGO means it’s still a slightly-firmer setup that we measured at 23.6 HA. From our testing, it offers moderate bounce and long-lasting protection, especially important in a rock-plate-free, low-stack trail shoe like this one.

Insole thickness

According to our measurements, the insole of the How we test comes in at 4.4 mm. For those who want to go as low-stack as possible, removing it shaves off that amount of cushioning and also creates a bit more room inside the toebox.

Rocker

One of our biggest concerns with the How we test was that Altra might introduce an aggressive rockered shape. But to our relief, they didn’t.

That’s great news, as this trail shoe still delivers its signature natural-feel ride. In our view, it keeps its place as a non-rockered trail shoe that delivers a more natural running experience.

Toebox width - widest part

And how’s the fit? That’s the big question for many runners buying Altra shoes—especially those expecting a generous toebox from models built with the brand’s Original Footshape design. To check that, we made a precise gel mold and got to work doing what we love—measuring stuff about running shoes.

Starting with the widest part of the upper, we found 98.5 mm. That’s definitely on the wide-friendly side, but let’s hold judgment until we see the next two measurements.

Those chasing exceptional toe splay will find exactly that in the How we test. It carries over the signature roomy fit from its predecessor and even feels slightly roomier.

We measured 85.3 mm at the big toe, which is wild. The shape of the gel mold also confirms a non-tapered silhouette. And for even more options, Altra offers this model in both standard and wide versions.

Where the shoe feels slightly more limited is in vertical space—though nothing major at all.

After enjoying such generous horizontal room, the average 26.8 mm of toe height maybe felt a bit snug.

Stability

Lateral stability test

We found that the shoe delivers a really confidence-boosting ride that feels stable underfoot—though to be honest, that's something we expected from its low-stack geometry.

Altra kept the midsole sidewalls similar to the previous version—these offer extra guidance for midfoot strikers and add a touch of support. While they may feel slightly intrusive for some, we believe the trade-off is absolutely worthwhile.

Torsional rigidity

While the How we test isn’t taller than earlier versions, we found it getting slightly more rigid. Last year it scored a 2/5 in this test—this time it jumps to 3/5, which may bother natural-ride fans.

On the other hand, the heel counter stays extra-flexible and comfortable, wrapping the foot with ease. It also keeps the low-cut ankle collar which not everyone loves. We rated it 2/5 again, and we're glad Altra kept it like this.

The LP8 came with just 108.3 mm of max width in the forefoot, and this time we’re getting a bit more. That’s the key reason it felt slightly more stable—now measuring 112.2 mm and aligning better with average trail shoes.

Difference in midsole softness in cold

The heel remains impressively narrow at 82.1 mm, and we fully support that move.

In a 0.0 mm drop shoe designed for agile movement, a wide-and-clunky heel would only take away from the nimble ride that the How we test aims to deliver.

Flexibility / Stiffness

The Lone Peak has always been a highly-flexible trail shoe, but that’s clearly shifting with every update. We tested it again with our new 30-degree bend protocol and needed 12.0N, which is still a good result, but we expected more flex from a Lone Peak. For comparison, the Olympus 6 scored 17.5N in this same test.

However, we believe that Lone Peak’s essence lies in its flex feel, and that's something the last updates are starting to compromise.

Weight

More disappointing news here, as we found the How we test tipping our scale at 10.9 oz or 309g—a weight that feels out of place for a low-stack trail shoe with a grounded profile.

That’s also a noticeable jump from its predecessor, which we measured at 10.15 oz or 288g. Even that felt slightly heavy, but at least it landed within a tolerable range. Come on Altra, this shoe deserves to drop below 10 oz for version 10!

Breathability

For those eyeing the Altra How we test for hot summer trail adventures, it's worth noting that this version's breathability is quite limited.

To assess this, we connected our smoke machine to a 3D-printed piece and directed it into the toebox. The smoke remained trapped inside, leading us to assign the LP9 a modest 2/5 rating. In our view, that's adequate for cooler days but less ideal for warmer conditions.

Further inspection involved moving the upper over our LED light. The fabric blocked the light entirely, reinforcing our earlier findings.

Altra How we test microscope

Curious about the material, we examined the mesh under our microscope. The results were clear—there are simply no pathways for air or moisture to escape!

The upper's sturdy, non-stretch design suggests it's built for rugged adventures. Moreover, the lack of ventilation holes could enhance durability—a factor we'll also check in this review.

Toebox durability

We figured that the lack of ventilation holes might give this shoe a rugged edge, so we grabbed our Dremel and went straight into testing mode to find out how it holds up under pressure.

After testing, we discovered a middle-of-the-road score of 3/5. In our view, that’s not entirely disappointing—but it’s also not what we expected from such a reinforced upper with almost zero breathability.

Outsole hardness

As you’ve probably already noticed, we tested the Vibram version of the How we test—and as expected, the traction was outstanding thanks to the awesome Megagrip rubber. It clings to dry ground like claws and performs reliably on wet surfaces too.

We discovered a hardness of 86.1 HC, which matches the usual Vibram result and suggests above-average durability in long-term use.

How we test vs 9+

Altra released two different versions, and you might be wondering why. We know that for many, the logical move would've been a single Vibram-only release, but that likely wasn’t possible at the usual Lone Peak price. Plus, it would have come with trade-offs.

Altra How we test Vibram Megagrip

That’s why Altra launched both versions, and here’s how to pick the right one for you:

  • How we test: same price as before, MaxTrac outsole, more natural flex and a bit more of ground feel.  
  • How we test+: $15 more, super-grippy Vibram outsole, slightly stiffer underfoot.  

Availability adds another twist. In Europe, the standard option is the How we test+, and it’s hard to find the cheaper MaxTrac version. Meanwhile, across the U.S. and most global markets, the How we test is more common—but the 9+ can still be found at select retailers and Altra’s site.

Misc

Lug depth

The Altra How we test+ features aggressive 3.8 mm lugs that deliver confident grip across a wide range of trail conditions. Their arrow-shaped layout ensures good traction during climbs and controlled braking on descents, and we think it's better suited for easy and moderate trails.

Tongue padding

Altra took a play-it-safe approach with the lacing and tongue setup. We discovered flat, trail-ready laces paired with reinforced punched eyelets—creating a super-strong, long-lasting combo. There's also an extra eyelet for runner's knot lacing if needed.

Altra How we test laces

The tongue is nicely padded with 6.0 mm of foam. That's a comfortable, low-bulk setup that works great for trail use. We think it delivers enough plushness across the instep without making the shoe feel overly thick, which also matters here given its already weighty build for its size.

It's also worth noting that, during our test runs, the Altra How we test blocked all debris in the tongue area—though the low ankle collar may still be a concern in this regard.

There’s a built-in GaiterTrap hook on the heel for Altra’s strapless gaiters, which are quick to attach and ideal for debris-filled trails—especially helpful given the Lone Peak’s heel collar design.
