Topo Phantom 4: análisis y review

In our experience, the Topo Phantom 4 is a strong choice for:

• Runners who liked previous Phantom versions and want the most cushioned and refined update yet.
• Those looking for a reliable daily trainer with a wide, foot-shaped forefoot.
• Anyone with high-volume feet who need an upper that offers generous space in all directions.

The Phantom 4 still relies on ZipFoam, and we found in the lab that its energy return remains low. If you’re chasing a more modern-foam sensation underfoot, we do not recommend this one. From our perspective, options like the Altra Experience Flow 2 or the New Balance FuelCell Rebel v5 deliver a more bouncy experience at a similar MSRP.

We also think it’s not the best choice for runners with low-volume, narrow feet. In our experience, the roomy, anatomical fit can feel overly spacious and hard to lock down. Check the PUMA Magnify Nitro 3 or the HOKA Mach 6 instead.

One of the defining traits of the Topo Phantom 3 was its limited shock absorption. With the market clearly shifting toward more highly-cushioned designs, it’s no surprise that this version delivers greater underfoot protection, registering 139 SA in the heel and 112 SA in the forefoot.

However, bounce is still missing from the equation. With just 49.4% energy return in the heel and 53.3% in the forefoot, the Phantom 4 feels flat underfoot and does not reward faster paces, so it’s worth keeping that in mind.

The Phantom 5 needs, at the very least, a supercritical EVA foam as soon as possible.

Topo hinted at a 2 mm stack height increase in the Phantom 4, and our measurements confirmed it. At 34.6 mm of total stack in the heel, there’s a small yet noticeable bump for heel strikers that brings the shoe closer to the current daily trainer standard.

The forefoot also gains additional foam, although the increase is more modest than in the heel. We measured just 0.8 mm more, bringing the total stack height to 27.6 mm.

The heel-to-toe difference measured slightly higher in our lab than what Topo Athletic states. While the brand lists a 5 mm drop, which is even printed on the shoe, we recorded 7.0 mm. It remains best suited for midfoot strikers, yet versatile enough to accommodate a wide range of runners.

Topo also claims that the ZipFoam formula was updated to deliver greater softness in this version. We verified that, as it's clearly softer than previous Phantom models, although this change does not translate into improved responsiveness as we proved before.

Using our Asker C durometer, we measured the foam at 33.2 AC, a result that closely matches the soft-leaning feel we experienced during our runs.

The added stack height also introduces a slightly more pronounced rocker, with a steeper curvature, particularly in the heel. It’s not a dramatic shift if you’re coming from version 3, but it does help nudge the shoe toward a more modern geometry.

Topo is widely recognized in the running shoe industry as a strong alternative to Altra’s anatomical fit, offering a similar foot-shaped design but with higher drops, and they stay true to that philosophy here.

The Phantom 4 began our fit assessment with a forefoot width of 96.7 mm, yet with this brand, it’s the second measurement that truly defines how the shoe fits.

Our second measurement, taken directly in the toebox, came in at 80.4 mm. That’s an unusual figure in the lab, yet entirely consistent with the foot-shaped design philosophy that defines Topo shoes.

There is also generous vertical space in the toebox, allowing the toes to move freely without feeling restricted.

In our third and final fit measurement, the Phantom 4 again scored above average, reaching 31.1 mm.

In our traction test, the outsole recorded a 0.50 score, marking a slight step forward from its predecessor.

While it’s far from the best in pure traction performance, it delivers reliable grip on dry pavement and remains steady in light rain too.

The outsole design has been fully reworked, now extending more coverage into the midfoot area and addressing the weak point found in its predecessor.

Unfortunately, it may not be immediately obvious to you due to the color combination of this version, but it was the only one available at the time of our purchase.

To evaluate longitudinal stiffness, we performed our standard 30-degree bend test and recorded a force of 12.9N to flex the Phantom 4. That’s only a slight uptick compared to the previous version and not something we noticed while running.

This result places it squarely within the average range for daily trainers, flexible enough to be comfortable at easy runs without feeling overly unstable.

The redesigned outsole is largely responsible for the 4% weight reduction in the Phantom 4. It may not be a groundbreaking change, but a lighter build is always welcome in a daily trainer.

Still, we can’t help but wonder how much more dynamic this shoe could have felt with a supercritical foam instead of the current ZipFoam.

The upper of the Phantom 4 is a clear example of why lab testing shoes matters. Simply judging it by appearance or relying on a few winter test runs would lead us to misleading conclusions.

At first glance, the mesh looks packed with ventilation holes, and visually, it suggests strong airflow. However, beneath that outer layer sits a secondary lining that restricts most of the ventilation, which ultimately led us to assign it a 2/5 in breathability.

Once we examined the material, the explanation became obvious. Having a thick upper means that airflow is significantly limited despite the perforated appearance.

Previous Phantom versions featured larger openings and earned a 3/5 score, so the drop in ventilation this time around didn’t come as a surprise.

As is usually the case with Topo, the upper feels well constructed and durable, leaving us with few structural complaints. Still, runners who log miles in hot summer conditions should be aware that this shoe retains heat, which could become a drawback in warmer climates.

The Phantom has long sat between a neutral trainer and a mild stability option. With the softer foam in this fourth version and a few changes, it leans more clearly toward the neutral side and it's not a good option for those with support needs.

The redesigned outsole also results in slightly reduced torsional rigidity, which aligns with our earlier observation that the shoe now feels more neutral in character. In our assessment, it earns a 3/5 from the 4/5 of its predecessor.

The plastic heel clip from version 3 has been removed, and as you may guess, that change makes the shoe feel more neutral and slightly less stable in the heel area. Here, it scores a 2 out of 5 in our test.

The shoe’s platform dimensions have also been revised compared to version 3, and the Phantom now presents a narrower footprint. We measured 109.8 mm in the forefoot, which is well below average and 3.5 mm less wide than its predecessor.

The heel platform also stays below average at 87.1 mm, a characteristic we’ve seen repeatedly across many Topo models. Anyway, the brand has long leaned toward designs that favor midfoot and forefoot strikers.

Durability may not grab headlines, but it plays a crucial role in a daily trainer expected to log high mileage and likely see regular everyday use, especially among casual runners.

Beginning with the toebox, we recorded a solid 3 out of 5 in our abrasion test.

On a less encouraging note, the heel padding received the lowest possible score of 1 out of 5. That result will undoubtedly raise concerns for some runners.

The rubber compound in the Phantom 4 proves slightly more abrasion-resistant than in its predecessor, as we removed only 0.8 mm in our durability test. That’s a welcome improvement for runners aiming to maximize mileage and get plenty of life out of this shoe.

With 3.5 mm of rubber protecting the foam and solid abrasion resistance in our tests, the Phantom 4 shows strong durability potential. Early wear shouldn’t be a concern, aside from sections where the foam remains exposed.

The insole measures 4.1 mm in thickness, which is very much in line with what we typically see in daily trainers.

The Ortholite insole, promoted as featuring high-rebound foam, is fully removable and easy to swap out. However, based on our lab findings, its rebound performance is not exactly a compelling reason to keep it inside.

ZipFoam blends TPU with EVA, and thanks to this formulation, it maintains its softness impressively after 20 minutes in the freezer. In our test, it lost just 12%.

The Phantom 4 lacks reflective elements, perhaps something to look forward to in version 5.

Topo doubles down on its classic design by using two tongue lace loops to keep it centered, instead of the single loop found in most shoes. It has clearly become a recognizable trademark for the brand.

The tongue measures 6.4 mm in padding, striking a thoughtful balance between comfort and weight that suits the Phantom 4 especially well.

The tongue design we mentioned earlier likely stems from the absence of a gusseted construction. Although we would have preferred the tongue to be secured to the sides, it at least stays in place and doesn’t shift around like in many other shoes.

The heel follows Topo’s classic design, lacking a heel tab but incorporating structural reinforcements and displaying the shoe’s official drop.

The Phantom 4 comes with a slight price increase, which feels somewhat hard to justify given that energy return remains relatively low. It’s not a deal-breaker, as it still aligns with many competitors in the category, but it reinforces our view that a more energetic foam would help to keep this shoe competitive.
