Great
  • Gravel 85
  • Versatile 81
  • Technical 68
We think the Altra Timp 6 is exactly the kind of update that longtime Timp fans wanted. We found in the lab that Altra improved the midsole foam, increased the room in the toebox, and paired the shoe with a Vibram Megagrip outsole. The ride remains natural, flexible, and easy to trust on long days outdoors. In our opinion, it works wonderfully as an all-purpose trail companion for runners and hikers who value a zero-drop design, although the price increase pushes it closer to the premium zone than we'd like.

Pros

  • Ideal for wide feet
  • Vibram Megagrip outsole
  • Improved and softer midsole foam
  • Balanced cushioning with strong forefoot protection
  • Highly breathable for year-round use
  • Excellent toebox and outsole durability
  • Roomier fit than previous Timps
  • True zero-drop platform
  • Flexible build
  • More comfortable step-in feel

Cons

  • Low heel stability
  • Probably a bit overpriced
  • Weight increase
  • Not for narrow feet

Who should buy

The Altra Timp 6 could be your next shoe if you:

  • Want an Altra trail shoe that sits right between the Lone Peak and Olympus.
  • Are looking for a versatile zero-drop model that works equally well for trail running, hiking, and everyday outdoor adventures.
  • Found previous Timp versions a bit too snug and want a roomier fit that feels closer to Altra's classic models.
  • Need a well-cushioned shoe that remains flexible and natural, paired with a spacious toebox that allows your toes to spread comfortably.

Who should NOT buy

For runners seeking a zero-drop shoe with maximum stability, the Timp 6 is unlikely to be the best choice. Instead, we recommend looking at the Altra Olympus 6 or the lighter Olympus 275, both of which offer a more stable platform while staying true to Altra's zero-drop philosophy.

We also believe that heel strikers are not the ideal audience for the Timp 6 due to its geometry and narrow rear platform. Within the Altra lineup, the Experience Wild 2 is a more suitable option, while the Topo Ultraventure 4 stands out as an excellent alternative for those open to exploring other wide-foot-friendly brands.

Cushioning

Shock absorption

With 119 SA in the heel and 120 SA in the forefoot, the Timp 5 delivers a nearly level cushioning profile that fully embraces its zero-drop design. While the heel lands slightly below the trail-shoe average, the forefoot stands out when compared to most competitors.

Energy return

One area where the Timp 5 fell short in our testing was energy return. Fortunately, the Timp 6 delivers a meaningful upgrade, boosting rebound to 56.5% in the heel and 58.5% in the forefoot.

While these figures still don't rank among the best we've measured, they now feel much more in line with both current market standards for trail shoes. As a result, the foam no longer stands out as a weakness.

Heel stack

We always appreciate it when brands provide accurate stack height figures, although that's still more the exception than the rule.

Altra Timp 6 side details

Altra got it exactly right with the Timp 6, advertising a 30 mm heel stack that matched our digital caliper measurement down to the millimeter.

Forefoot stack

The forefoot came in just slightly lower than advertised at 29.2 mm versus Altra's claimed 30 mm.

However, we're talking about a difference of only 0.8 mm here, which is practically negligible in the real world. In our view, Altra deserves credit for being highly accurate once again.

Drop

As you may have already guessed from those measurements, the resulting drop is just 0.8 mm. That's such a tiny difference that no runner could realistically distinguish it from a true 0.0 mm setup while running.

Therefore, we confidently classify the Timp 6 as a genuine zero-drop trail running shoe.

Midsole softness

Updated
Note: Low measurement: softer. High measurement: firmer.

The Timp 5 leaned slightly toward the firmer side of the spectrum, but Altra has softened things up with the Timp 6. The updated EGO MAX foam feels definitely a bit more forgiving underfoot.

Using our Asker C durometer, we measured the midsole at 36.8 AC. According to our lab data, that places it squarely in the middle ground, avoiding both overly-soft and excessively-firm extremes.

Rocker

Trail shoes seem to get more aggressively rockered with every new release, but we're pleased to see that some brands still preserve the identity of some models. In our opinion, adding a pronounced rocker to the Timp would have been a questionable move, as many runners who keep returning to this series likely prefer the natural ride that comes with a more traditional geometry.

As our photo clearly shows, the Timp 6 stays true to that philosophy. The forefoot features just a subtle amount of rocker to help smooth transitions, but the overall design remains refreshingly old-school, avoiding the highly-curved profiles that now dominate much of the trail market.

Width / Fit

The Timp series has long been a reliable option for runners with wide feet, although it has never ranked among the roomiest models in Altra's lineup. However, after evaluating the sixth generation, we came away with a somewhat different impression.

We created a gel cast of the shoe's interior to compare it against both competing models and previous Timp versions. The very first measurement revealed an impressive width of 99.2 mm.

Toebox width

However, the area where Altra traditionally separates itself from the competition is the toebox.

This is also where the Timp 6 has the biggest fit update, as we measured a generous 81.9 mm compared to the 79.6 mm recorded in the previous version. In our view, this extra space helps explain why the shoe felt to us more Olympus than Timp.

Toebox height

The Timp 6 also offers plenty of vertical space in the toebox, enhancing overall comfort while allowing the toes to move more naturally. In addition, this extra volume can help improve air circulation inside the shoe.

Our third measurement confirmed this generous design, revealing 28.6 mm of toebox height.

Traction / Grip

Lug depth

The Timp 6 uses 3.3 mm lugs that, in our experience, are better suited for gravel roads, buffed-out trails, and hard-packed terrain than truly technical routes. However, longtime Timp users are unlikely to be surprised, as this series has traditionally favored a shallower lug design over an aggressive setup.

Altra Timp 6 Vibram

We also noticed that the outsole lacks Vibram's Traction Lug technology. Given the shoe's high price tag, we believe its inclusion would have been a reasonable expectation.

Outsole design

Despite the absence of Traction Lug technology, the outsole uses Vibram Megagrip, one of the most trusted compounds in the trail-running world and a proven performer across a wide range of surfaces. In our opinion, that alone is enough to inspire confidence.

We also spotted Altra's signature outsole layout, which mirrors the structure of the foot's bones while leaving portions of the midfoot exposed to reduce weight and maintain the brand's distinctive design philosophy.

Altra Timp 6 Outsole design

Flexibility / Stiffness

Thanks to the outsole layout mentioned above, the Timp 6 delivers better flexibility than most trail shoes, requiring just 13.0N of force in our 30-degree bend test.

We were especially impressed by this result considering the substantial amount of foam packed under the forefoot, a setup that often leads to a noticeably stiffer ride.

Weight

Version 6 comes with a negative trade-off in form of added weight:

  • Altra Timp 4: 11.15 oz / 316g
  • Altra Timp 5: 9.5 oz / 269g
  • Altra Timp 6: 10.2 oz / 289g

While the Timp 6 is a major improvement over the Timp 4, it unfortunately gains a bit of weight compared to the Timp 5. We don't see this as a major drawback, but we were hoping Altra would at least maintain the previous model's weight rather than move in the opposite direction.

Breathability

Breathability test

Updated

Those who choose the Timp 6 will likely use it as their go-to trail shoe, handling everything from hiking to running and from winter to summer. Because of that, strong breathability is an important part of the package.

We placed the Timp 6 inside our temperature-controlled chamber, where a heated footform releases artificial sweat at a constant rate. Using advanced sensors embedded in the foot, we measured how effectively the shoe moved moisture away from the skin. And the Timp 6 performed very well and earned a solid score of 76 BR.

We also recorded a solid result in our second test, which evaluates a shoe's drying capability.

This assessment measures how much of the accumulated moisture the Timp 6 can release back into the air, effectively removing it from the interior. The Timp 6 managed a 50% result, which is certainly respectable, although it falls short of the best performers we've tested.

Stability

Lateral stability test

The Altra Timp 6 offers a stable ride for both midfoot and forefoot strikers, as its geometry naturally favors runners who land in these areas. However, heel strikers may find it slightly less supportive, since the rear platform is noticeably narrower compared to other trail shoes.

That said, we only recommend this shoe for neutral runners.

Torsional rigidity

Updated

Like most Altra shoes, the Timp 6 prioritizes flexibility and a natural ride over outright rigidity. Because of that, we weren't surprised to record a below-average result of 12.5 Nm in our torsional rigidity test.

This approach works especially well for runners seeking a trail shoe that offers a substantial amount of foam underfoot but that also allows the foot to move naturally, avoiding the stiff and restrictive feel often associated with highly-cushioned designs.

Heel counter stiffness

The heel counter is intentionally designed for comfort and freedom of movement rather than aggressive rearfoot support, which is why it earned a low 2/5 in our assessment. This further reinforces our earlier point that the Timp 6 is not the most stable option for heel strikers, particularly compared to shoes with a more structured rear section.

Nonetheless, runners who consistently land on the heel are rarely the target audience for a zero-drop shoe in the first place, making this trade-off less concerning for the runners most likely to choose the Timp 6.

Midsole width - forefoot

We were pleased to see that Altra kept the Timp 6 at a moderate width instead of pushing it into the extra-wide territory. 

Measuring 113.9 mm in the forefoot, it strikes a versatile balance that accommodates a wide range of runners and activities without feeling overly specialized, much like a daily trainer for the roads.

Midsole width - heel

The heel is exceptionally narrow at 84.4 mm, a design choice that helps keep the Timp 6 nimble and maneuverable whether you're hiking or running. However, as we noted earlier, that agility comes at the expense of rearfoot stability, especially for runners who tend to land on the heel.

Durability

Toebox durability

Altra reinforced the toe area with durable overlays, yet we targeted the engineered mesh itself during our toebox durability test. And even under those harsher conditions, the upper earned a strong 4/5 score, demonstrating impressive resistance to abrasion and suggesting excellent long-term durability.

Tongue padding

We were impressed by the Timp 6's lacing system, as it does an excellent job of spreading pressure evenly across the instep. The high-quality flat laces play a major role here too, helping create a secure and comfortable fit without unwanted pressure points.

Altra Timp 6 tongue

The tongue has also undergone a major redesign compared to the previous version. It now features a generously padded construction, measuring 9.0 mm in thickness. While this upgrade likely contributes to the weight gain we noted earlier, it also delivers a noticeable improvement in step-in comfort.

Price

The Altra Timp 6 arrives with a $10 price increase. The ride has undoubtedly improved thanks to the updated foam, and having the Vibram Megagrip outsole brings a premium touch. Even so, we feel the MSRP is a bit difficult to justify.

That said, Altra models frequently receive substantial discounts, and that can completely change the equation. Be sure to check the latest deals before making a decision!
