Our verdict

In our experience, the Women's Brooks Glycerin Stealthfit GTS 20 Running a great trail running shoe, but it comes with a few compromises. It's not designed for wide feet or technical terrain, and it's not the best for long distances. However, if these factors don't bother you, we believe this shoe offers a stable ride in a lightweight package. We were also impressed with the bouncy DNA Flash midsole and its outstanding performance on easy trails like fire roads, even at uptempo paces. We think that for runners who fit its specific profile, the Catamount 2 could be a great choice even at $170, combining speed with comfort in a way that's hard to beat.

Who should NOT buy

Brooks crafted the Catamount 2 primarily for narrow-to-medium width feet, making it a less suitable choice for runners with wide feet. Plus, since it's a trail shoe, a bit more room for toe splay is usually desirable, so we think it might not be the best pick for those runners.

If you fall into that category, we suggest considering shoes with wider toeboxes and similar features, such as the Saucony Peregrine 13 or the Brooks England Space-Frame-Tasche 3L.

Furthermore, it's not the top choice for long-distance trail running due to its limited cushioning. If you're deep into the ultra-world, you might want to explore options like the Чоловічі бігові кросівки brooks ghost 9 or the HOKA hombre pie normal negras.

Cushioning

Heel stack

One reason Brooks managed to keep this shoe relatively light compared to the competition is its low stack height.

zapatillas de running Brooks entrenamiento talla 35.5 naranjas stack
Hats off to Brooks for boldly placing such a cool design on the shelves!

With a heel height of 29.0 mm, it positions itself as a shoe suitable for short to medium distances, but not as the ideal choice for longer efforts.

Forefoot stack

The forefoot follows the same pattern as the heel, with a slightly lower stack than what's typical in trail shoes. This design again signals to every midfoot and forefoot striker that this shoe is best suited for runs lasting 1 to 2 hours.

Drop

Brooks officially stated a 6-mm heel-to-toe drop for the Catamount 2, and following the official guidelines, we measured it at 6.4 mm—a negligible difference.

This design makes the shoe more suitable for midfoot strikers, although a 6.4 mm drop is often considered a "universal" drop that can also provide a satisfactory ride for both forefoot and heel strikers.

Midsole softness

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

Transitioning to the midsole, we discovered a full-length slab of Brooks' DNA Flash. As extensively detailed in Brooks Ricochet 3 Azul Negro 1103611D494, DNA Flash is an EVA-based, nitrogen-infused foam famous for its lightness and speed-enhancing qualities. It's the same compound found in the fantastic Brooks Hyperion Max.

With a softness rating of 22.0 HA, we found it strikes a perfect balance, making it exceptionally well-suited for a trail running shoe.

Keep in mind that the ride might feel a bit firmer than expected due to the Pebax plate in the midsole. This feature not only offers stability and added protection but also doubles as a rock plate.

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

Since it's crafted as a shoe that can be used in winter, it's important to understand how it behaves under cold temperatures. What we found is that the softness varied to 25.9 HA.

From the moment we slipped our feet into the shoe, we felt it was pretty narrow, and our toebox measurements further confirmed this.

zapatillas de running Brooks entrenamiento talla 35.5 naranjas

Measuring 95.7 mm at its widest part, you can expect a race-oriented fit for normal feet, and an excellent fit for those with narrow feet. This feature is a side benefit for technical terrain, although it's clear that the shoe isn't primarily designed for challenging trails.

However, there's a catch. For those with wide feet only in the toe region, this shoe can be accommodating, as it features a very low taper in the toe cap. We measured 79.2 mm in that area.

Stability

Lateral stability test

The Catamount 2 is a neutral shoe, but it has a few tricks up its sleeve, such as the large DNA Flash walls on the medial and lateral sides, and the SkyVault plate.

zapatillas de running Brooks entrenamiento talla 35.5 naranjas running

While we believe it's best suited for neutral runners, those with mild stability needs can also use this shoe without any issues.

Torsional rigidity

Obviously, the lower stack height contributes to a stable ride. However, a significant part of this stability comes from the shoe's impressive torsional rigidity that we rated at 5/5.

This feature keeps the shoe really stable. But naturally, it results in less agility on technical terrain, making the Catamount 2 a shoe geared towards easy trails.

Midsole width - forefoot

One of the key reasons the Catamount 2 offers such a stable ride is its impressive midsole width.

At 116.3 mm, it's remarkably wide, greatly benefiting those with a midfoot or forefoot striking technique.

On the other hand, the heel width is just average, measuring 90.2 mm. This isn't bad news for heel strikers, but don't expect the same dimensions as you would find in a stability shoe.

Flexibility / Stiffness

We've already discussed the shoe's torsional rigidity, but what about its flexibility lengthwise? If it's too rigid, it could be uncomfortable for easy runs or even walking!

Luckily, in our 90-degree bend test, it scored just 29.1N, which is average.

The scale displayed a feather-light 9.7 oz (275g) on the screen, a delightful find for those seeking a lightweight trail running shoe.

Breathability

Brooks Cascadia 16 Trail Running Shoes Rojo take a different approach to breathability compared to From for Brooks because more isn't always better. In fact, in very cold countries, we might self shoes with less breathability, especially for winter runs.

That's why we believe a 3/5 rating is a nice balance for these shoes, which is exactly what the Catamount 2 scored after our smoke test.

Under the light, we spotted a very thin mesh, strategically reinforced on the sides to enhance stability. This design reduces breathability, which explains why there's so much airflow through the tongue.

We found an interesting engineered mesh with a thin outer layer for structure—unlike most shoes, which have this layer inside.

Lastly, we analyzed how Brooks structured the upper. Essentially, it's a road design but with additional layers for extra comfort and protection in certain areas.

Toebox durability

The upside of a thin, minimalistic mesh is it keeps the shoe lightweight and offers decent breathability. However, the major downside is the likely impact on durability.

During our first Dremel test in this lab review, the Catamount 2 only managed a 2/5. While it's not the absolute worst, it's far from impressive. However, Brooks has incorporated some robust protective features on the toe cap, effectively shielding the upper against a significant amount of potential damage.

After thoroughly assessing the toebox, we shifted our focus to the heel area, where we discovered a significantly more impressive result.

Outsole hardness

Turning the shoe over to examine the outsole, we began by checking the hardness of the rubber with our durometer. At 84.5 in the Shore HC hardness scale, it's pretty much average.

Outsole durability

Now that we've established the outsole's average hardness, we believe the real test is the Dremel evaluation.

For the Catamount 2, our measurements showed an indentation of just 0.7 mm—a good result that promises a durable, long-lasting outsole.

Outsole thickness

Last but not least, we checked the thickness of the outsole.

At 2.5 mm, there's enough rubber, though we think it's slightly too much as it can somewhat mute the ride. For this shoe, with its impressive durability performance, we would have selfred an outsole thickness between 1.5 and 2 mm.

Misc

Lug depth

We mentioned earlier that we viewed the shoe, based on its stiffness, as better suited for easy trails. Now, this is 100% confirmed after measuring the lugs at 3.0-mm long.

The outsole boasts a generous amount of exposed foam to minimize weight, complemented by variously shaped lugs that significantly enhance traction.

In fact, we see the Catamount 2 as being on the verge of a road-to-trail shoe.

Brooks clearly focused on cutting as many ounces as possible, and the thin, 3.7-mm tongue is a testament to their efforts.

Tongue: gusset type

The semi-gusseted tongue provides an excellent lockdown. While we usually self fully-gusseted or bootie tongues in trail running shoes, in this case, we think this design is a good choice by Brooks.
