Altra Paradigm 8 review

The Altra Paradigm 8 is a shoe made for:

• Runners with low to moderate stability needs who want a zero-drop shoe.
• Anyone looking for a flat midsole that feels natural for both walking and running.
• High-mileage runners who want a durable Altra daily trainer with a bit more stability than the Torin 8.

We found that the Paradigm 8 only shines for midfoot and forefoot strikers, and in our experience heel landings feel awkward with its zero-drop design. Therefore, we do not recommend it for heel strikers, and options like the ASICS GT 2000 14 or Brooks Adrenaline GTS 24 deliver a better ride for that group of runners.

We also think the EGO MAX midsole lacks bounce. After testing, we discovered its energy return is really low for the price point of the shoe. We believe there are better choices if you are looking a bouncy-yet-stable feel, such as the Saucony Hurricane 25 or the Adidas Supernova Solution.

As with most zero-drop shoes, the shock absorption feels very similar across the midsole of the Paradigm 8. We tested it and found 116 SA in the heel and 109 SA in the forefoot, which is one of the first signs that this shoe favors midfoot or forefoot striking more than heel landing. Just use our charts and see how it compares in the heel and forefoot against other shoes...

The Paradigm 8 and found it uses Altra’s EGO MAX midsole, which is marketed as a step above EGO. However, it felt dated to us, and that's clearly reflected in our energy return results of just 47.5% in the heel and 50.2% in the forefoot.

From our perspective, the Paradigm needs a foam update to something like EGO P35, as seen in other recent Altra models like the Experience Flow 2. While EGO MAX works fine for easy runs or walking, we found it feels slow and dull once pace increases.

Altra lists a 30 mm stack, and we measured 29.4 mm in the heel. That’s fairly limited for long distances, although as we noted earlier, this shoe is clearly not designed for heel striking except maybe when walking.

With 27.3 mm of cushioning in the forefoot, the Paradigm 8 sits above average and can support longer efforts for runners who land on the midfoot or forefoot. That amount of foam does real work where it matters for this type of stride.

This is a zero-drop shoe, and while we tested it and measured a 2.1 mm difference, this sits well within normal manufacturing tolerances from the insole, foam, or outsole rubber.

It feels truly flat on the run and delivers the expected ride of a real zero-drop design, but as we always warn: runners coming from high-drop shoes should transition slowly and with care to reduce injury risk.

Altra has slightly adjusted the EGO MAX foam in the Paradigm 8 to make it softer than in the previous version. The Paradigm 7 measured 19.4 HA, while we recorded 17.5 HA this time, which brings a more forgiving feel underfoot.

This change helps the shoe feel more in line with current expectations. The softer tuning improves comfort on easy and long runs without turning the ride overly plush or unstable, keeping the Paradigm 8 clearly positioned as a supportive daily trainer.

As you can see in our photo, the Paradigm 8 features a very light curve in both the forefoot and heel, which promotes a natural feel underfoot and fits the purpose of this shoe well. It’s good news that Altra keeps this model rooted in a classic design.

The Paradigm 8 continues to use Altra’s Standard FootShape last, which sits between the wider Original and the narrower Slim options. It’s the brand’s middle-ground fit.

In our first measurement, we recorded a very standard 95.8 mm. That gives about the same room in the ball of the foot as many other shoes, so we needed to dig deeper to see where the fit really stands.

Here’s where the Paradigm 8 really stands out. With 82.3 mm of toebox width, it offers loads of room for natural toe splay, making it a great option for runners with wide feet or anyone who prefers a truly foot-shaped running shoe.

Toebox height comes in at a solid 26.2 mm, providing a standard amount of room that feels comfortable for both running and walking.

We don’t expect most runners to run into any issues here.

There’s a small step back in traction compared to the previous model, dropping from 0.55 to 0.50 in our test. It’s far from a deal-breaker, as the change is minor and likely unnoticeable on the run, and the score is still solid on both dry and wet surfaces.

The outsole design has changed slightly, with less rubber than version 7, which helps explain the small drop in traction. It still keeps Altra’s familiar layout, using flex cutouts that follow the natural shape of the foot bones, along with a reinforced medial area to protect against early wear from pronation.

We secured the Paradigm 8 to our machine and flexed it to 30 degrees, measuring 15.1N. It’s a balanced result overall, although we honestly would have liked to see a bit more flexibility.

We put the Altra Paradigm 8 in our scale and found 9.8 oz or 278g, which is about 5% heavier than its predecessor. Similar to what we saw with traction, this increase is not a deal-breaker, but it's there.

The weight still sits in a reasonable range, yet we honestly hoped for a reduction instead of a gain in this update. This is another area where a better foam choice would help immensely.

Right away, we noticed that the Paradigm 8 upper looked more dense than light or airy, but looks can be misleading, even for us.

Using our smoke machine, we found decent airflow, which was definitely good news. As a result, we gave it a 3/5 score on our breathability scale.

When we held the upper against a light to see how much passed through, the result was similar. It’s clear this upper was built with priorities other than airflow, as it blocks most light.

We also examined the engineered mesh under our digital microscope and found very tight yarns, with little space for air to move through and no large ventilation holes.

It’s clear to us that Altra focused more on durability and support than breathability, which makes sense given the Paradigm’s role in Altra's lineup.

The Altra Paradigm 8 delivers non-intrusive support through Altra’s GuideRail sidewalls and a wide, supportive midfoot platform.

This setup gently keeps the foot centered without feeling restrictive or forcing correction. Compared to earlier versions, it feels a bit more stable overall, likely due to its slightly reduced flexibility, which adds a more controlled ride.

Twisting and bending the shoe is harder than some might expect from an Altra, but with nearly 30 mm of stack height across the platform and a thick layer of outsole rubber, achieving more than a 3/5 in flexibility would have been difficult.

We were a bit surprised to find a flexible, 2-out-of-5 heel counter with no rigid parts, which is uncommon for a stability shoe. That said, as we noted earlier, the Paradigm suits midfoot and forefoot strikers best, so prioritizing comfort over heel rigidity may actually be the right call.

The shoe is not especially wide, and that’s exactly how it feels on the run, which is why we see it more as a moderate stability option rather than a full support shoe like the ASICS Gel Kayano 32.

This works well for runners who want a bit of extra support without a bulky feel, especially since the 113.2 mm width is even narrower than the average shoe.

The heel is also slightly below average at just 90.2 mm, but it’s important to note that the midfoot is very wide, which plays a key role even in a moderate-stability shoe.

In our view, these reasonable dimensions make it ideal for everyday use or even for doubling as a zero-drop walking shoe.

During our first hands-on with the Paradigm 8, we noticed that the upper clearly leaned more toward durability than ventilation, and we tested it to confirm that impression.

The Paradigm 8 fully delivered here, earning a very strong 4/5 score in our first Dremel test, which confirms its durable and well-built upper.

Heel padding also scores well at 4/5, which is a meaningful improvement over the 2/5 we measured in the previous version and helps reduce the risk of early wear for some runners.

In our final Dremel test, the outsole showed a strong result with just 0.9 mm of rubber worn away, which is especially important for a stability shoe.

Altra knows many runners with pronation issues wear out the outsole faster than neutral runners, so they added extra rubber to deliver a much longer lifespan. Instead of the usual ~3 mm found in most daily trainers, we measured a whopping 4.4 mm.

The stock insole sits on top of the EGO MAX foam and adds 5.0 mm of extra cushioning to the Paradigm 8.

You can remove the insole and swap it for a custom one without any issues. The only challenge is finding an insole that truly matches Altra’s foot-shaped toebox.

We found that the Paradigm 8 became 20% firmer after spending 20 minutes next to our ice creams, which is actually a good result.

Altra skipped reflective elements on the Paradigm 8, and we can’t say we agree with that choice. They’re always a welcome bonus.

We tested the lacing system and found that it keeps the same concept as before, with punched eyelets and a central lace loop, but Altra refined it since the previous version felt hit or miss.

We also discovered that part of the added weight comes from the new tongue, which now has much more padding at 9.9 mm, nearly double what version 7 had, and whether this feels like a good change will depend a lot on personal preference.

The tongue is partially attached to the sides, which helps keep it in place, but the design could be improved with a taller gusset that provides a more secure wrap.

The Paradigm 8 drops 10 bucks from its predecessor, and we double-checked it because price cuts are almost unheard of in the running shoe world. We’re so used to increases that seeing a decrease feels surreal.

That said, the Paradigm 7 was clearly overpriced, and version 8 still sits near the limit for what it offers. And of course, if the Paradigm were selling like hotcakes before, Altra wouldn’t be lowering the price...

The heel features a horizontal finger-loop tab that feels borrowed from a trail shoe design.
