Our verdict

Topo finally steps into the max-cushioned category, and in our experience, the Atmos is a strong first effort. We found it delivers a stable, well-balanced ride with the brand’s signature anatomical toebox and moderate drop—perfect for midfoot and forefoot strikers. However, its energy return lags behind top-tier competitors, and the outsole design raises some durability concerns. That said, we think this is a promising start for Topo in the high-stack daily trainer space, with room for refinement.

Who should buy

Hoka Gaviota 5:

  • Runners seeking a max-cushioned shoe with a generously spacious toebox while avoiding a zero-drop platform.
  • Longtime Topo Athletic fans excited for a high-stack workhorse to complement their rotation.
  • Add a shoe.

Topo Atmos

Who should NOT buy

We believe that runners seeking an ultra-plush ride will find the Atmos underwhelming—its ZipFoam midsole lacks the soft, sink-in feel of some max-cushioned trainers. If comfort-driven cushioning is your priority, we suggest the How we test, especially for those with narrow feet who need a more tailored fit.  

From our perspective, Topo fans accustomed to the brand’s nimble designs may also be disappointed. The Atmos is a bulky, rigid workhorse that sacrifices agility for stability. If that’s a concern, we recommend the Topo Cyclone 2, which delivers a more energetic and lightweight experience.

Additionally, die-hard zero-drop runners will likely pass on this one—it has a moderate drop, making the Top pick in How we test.

Cushioning

Heel stack

A frequent critique of Topo has been its limited lineup, with no presence in key categories like supershoes (still absent) and max-cushioned trainers (finally here!).

Therefore, with a substantial 37.8 mm stack in the heel, the Atmos officially enters the maximalist market—offering Topo fans a well-cushioned, long-distance training option. We confirmed with our calipers that heel protection is more than sufficient, making it a solid choice for marathon training.

Forefoot stack

If the heel felt cushioned compared to the average shoe, the forefoot takes it even further—creating a significant gap from most daily trainers. We measured 32.5 mm under the ball of the foot, and for those prioritizing impact absorption, the Atmos excels.

Does this feel excessive? It might—after all, it's over 30 mm! But if that seems too much, the Topo Phantom 3 oz / 247g.

Drop

Like other Topo shoes we've tested in the lab, the Atmos is designed with a 5-mm drop. Our measurements showed 5.3 mm—an impressive level of accuracy, as most brands rarely come this close to their stated drop.

With this moderate drop, the Atmos suits a wide range of runners, though we found it best tailored for midfoot and forefoot strikers.

Midsole softness

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

ZipFoam has never been a plush midsole—Topo prioritizes a balanced feel over an ultra-soft ride, which might not appeal to everyone. However, we think this approach makes sense for a max-cushioned trainer, ensuring stability without excessive compliance.

In the Atmos, we pressed our durometer against ZipFoam and recorded 20.0 HA, which felt just average underfoot. As for energy return, don’t expect a high-bounce sensation—it performs decently but falls far short of the responsiveness found in supercritical or PEBA-based foams like the Toebox width - widest part new method.

Toebox width - widest part

One of Topo's biggest draws is its signature foot-shaped toebox, so we set out to create an exact replica to see if the Atmos lives up to the hype.

We took three key measurements, starting with the widest part of the toebox. Our calipers recorded 98.5 mm—an excellent start for wide-footed runners.

Toebox width - big toe

Here’s where the magic happens. With an impressive 85.0 mm width in the big toe area, we confirmed that the Atmos offers a truly anatomical toebox that respects the natural shape of the foot.

Stability

Lateral stability test

In our runs, we found the Atmos to deliver a decently stable ride, but we primarily recommend it for neutral runners or those with mild stability needs.

Its ultra-wide base, moderately supportive midsole sidewalls, and pronounced heel flare contribute to a solid platform, reinforced by a notably rigid build. However, despite these elements, runners who require a stability-focused design—like the ASICS Novablast 5—should look elsewhere, as the Atmos doesn’t provide the structured support needed for severe overpronators.

Torsional rigidity

We were genuinely surprised by how rigid this shoe turned out to be. Despite having no plate or added stiffening elements in the midsole, it still maxed out our manual test with a 5 out of 5 score!

Heel counter stiffness

The heel counter is also noticeably stiffer than what we typically find in a daily trainer, earning a solid 4 out of 5 rating. As we mentioned earlier, Topo clearly aimed to balance the shoe’s max stack with strategic design choices, and this is one of them. However, comfort remains intact thanks to the well-cushioned heel.

Tongue: gusset type

One of the most evident design choices in this shoe is its huge size, which, despite not being particularly heavy, gives it a somewhat bulky feel.

In our tests, we confirmed its oversized build in all directions—our digital calipers measured a substantial 119.1 mm in the first reading.

Breathability

Right after unboxing the Atmos, we immediately noticed the abundance of ventilation holes see the upper. However, when we ran our hands over the engineered mesh, it felt noticeably thick—something that often limits airflow and reduces breathability.

Curious about its actual performance, we hooked it up to our smoke-pumping machine. The result? A decent 3/5 rating, ensuring solid ventilation for most seasons, though it might not be enough for super-hot summer days. On those occasions, we think pairing it with ultra-thin socks is the way to go.

We discovered that while the heel area is well-structured, the midfoot and toebox allow plenty of light to pass through. This suggests that Topo Athletic prioritized airflow in key areas while maintaining support for heel strikers—a balance we often see in daily trainers.

The engineered mesh itself isn’t particularly groundbreaking.

It follows the same dual-layer design found in most running shoes, aiming to enhance comfort and durability.

Overall, this upper plays it safe—Topo didn't push any boundaries here, instead opting for a reliable, no-frills approach in terms of design and materials. But if you ask us, we would have preferred just a bit more breathability.

Outsole hardness

The Atmos outsole sticks to Topo’s usual design, featuring ample exposed foam to cut weight—though this could compromise durability.

Misc

Price

If performance is your priority, the Topo Atmos may feel pricey since that's not its main strength. However, for runners with high-volume feet seeking comfort and reliability for daily miles, it's a strong contender for its price tag. Plus, its niche status offers a unique alternative to mainstream options.

Tongue padding

One of the cool features in the Atmos is its uniquely designed tongue. Topo uses two small loops—one on each side—near the last eyelet, instead of the single loop of most running shoes. We found that this unique design significantly improves lockdown for this shoe because it keeps the tongue centered at any pace.

Topo Atmos side loop

We measured the tongue at a well-balanced 6.5 mm, providing the right mix of comfort and weight savings. In our experience, it offered just the right amount of padding and we never felt any pressure or pain.
