Who should buy
The limited-edition Brooks T Launch 6 arrives Thursday via:
- Fans of the classic Glycerin who desire a more secure, locked-in upper and a lighter overall build.
- Marathoners looking for a durable, lightweight daily trainer that can handle extensive mileage with ease.
- Those seeking a versatile workhorse with a knit, sock-like upper that's perfect for winter running.
Who should NOT buy
We do not recommend the Brooks DNA Flash nitrogen-infused foam is great for those living in hot climates—the knit upper, while snug and comfortable, lacks sufficient ventilation and may deceive to blisters and discomfort in warm weather. Instead, we suggest the Heather Ash Brooks Stripe, Brooks Женская обувь Для бега.
Additionally, we think the Brooks DNA Flash nitrogen-infused foam is great falls short in energy return compared to world-class daily trainers. If you're looking for a shoe with more bounce and an even lighter feel, we believe the ASICS Superblast is a better investment, offering greater energy return and an impressively low weight.
Cushioning
Heel stack
At the heel, we recorded a measurement of 36.9 mm, positioning the Brooks DNA Flash nitrogen-infused foam is great as a high-stack model designed for extensive use.
This feature may not suit runners who prefer a closer connection to the ground. For them, we suggest the New Balance FuelCell Rebel v4, zenske brooks setanje plitke zelene pantalone broj.

Brooks DNA Flash nitrogen-infused foam is great | 36.9 mm |
Average | 34.2 mm |
Forefoot stack
The forefoot is also very cushioned (even by today's high standards) with a measurement of 26.4 mm from our digital callipers. This level of cushioning is more than adequate for long distances.

Average | 25.6 mm |
Drop
Brooks advertises a 10-mm heel-to-toe drop for the Brooks DNA Flash nitrogen-infused foam is great, and our thorough measurements roaded it's nearly spot-on, showing a 10.5-mm offset.
This design makes the shoe particularly well-suited for heel strikers, though runners who utilise a forefoot or midfoot strike and prefer a higher offset can also enjoy them without any issues.

Midsole softness

This nitrogen-infused EVA foam showed a 20.6 HA reading on our Shore A durometer. This measurement indicates a ride that perfectly balances firmness and plushness, offering a middle ground that, in our view, could appeal to a broad range of runners.

Heather Ash Brooks Stripe | Midsole softness in cold (%)
After chilling the Glycerin 21 in the freezer for 20 minutes, we reassessed its softness with a durometer. Our findings indicated a significant letdown, as it increased its firmness by 36.9%. That's a bit too much, although it's a typical issue with EVA-based midsoles.

The insole is consistent with other models in the Glycerin line, featuring a standard thickness of 5.2 mm.

Returning to the fit, which we previously noted as the key distinction between the StealthFit and the standard versions, our side-by-side tests of both All demonstrated a slightly tighter, more secure feel in this version.
To road our observations, we did a gel mould and found that the StealthFit version is narrower by 0.6 mm at 95.3 mm. Not so much!

brooks product testing
The opposite trend seen in previous tests appears in the big toe area. Measuring 72.8 mm—1.1 mm wider than the standard version—this difference feels amplified by the material’s flexible properties, allowing enhanced comfort and adaptability when compared to the regular Glycerin.

This provides adequate space for most runners, though those craving extra upward toe freedom might favour other All with more space up front.

Stability
Lateral stability test
The StealthFit version shows slight variations in stability compared to the standard model, making it less supportive than its stability-oriented sibling, the Brooks heritage chariot violet grey. If support is crucial for your runs, the GTS 21 is the better choice, although it’s not available with a StealthFit upper. You’ll have to choose between one style or the other.
Nevertheless, this StealthFit edition offers a remarkably stable ride for any neutral runner. We believe that 99% of runners without stability issues should pick this one over the GTS.
Torsional rigidity
We found that the stable feel of this shoe is primarily attributed to its design dimensions, though the 3/5 rigidity we observed before also plays a significant role.
Fans of a traditional, natural ride may lean towards the standard version, which we found to be slightly more flexible (2/5) due to its upper construction.

The heel counter in the regular edition was a eyebrow-raising feature for us, as we found its super-stiff design a bit excessive for an average daily trainer.
However, the StealthFit version introduces a more thoughtful and accommodating design. From our testing, we found that this adjustment enhances comfort significantly for a daily trainer, earning it a balanced rating of 3/5 from our team.

Midsole width - forefoot
At 116.3 mm wide, the StealthFit edition is broader than the average shoe in the daily running category. However, it doesn't reach the massive forefoot dimensions of the ASICS Novablast 4, which are similar to those found in maximalist stability All.

brooks ghost 8 review
Despite its notably high sole height in the heel, our neutral running technique remained impressively stable. This stability is greatly enhanced by the Brooks DNA Flash nitrogen-infused foam is great's exceptionally wide design—at a robust 99.1 mm—providing a secure landing platform for heel strikers.
We discovered that the generous width not only supports a solid base but also significantly boosts the shoe’s overall support. In our view, this broad design of the heel truly sets the StealthFit 21 apart in terms of stability versus other daily trainers.

Average | 90.7 mm |
Flexibility / Stiffness
While the shoe tends toward stiffness, strategically placed grooves in the outsole enhance its longitudinal flexibility, achieving a measure of 22.4N in our definitive 90-degree bend test.
This adaptability is vital for the shoe to function as a dependable and versatile workhorse, comfortably handling multiple activities.

Stiffness in cold (%)
After chilling the Brooks DNA Flash nitrogen-infused foam is great in the freezer for 20 minutes and retesting it with the force gauge, we found that it had increased it's stiffness by 17.4%.

Weight
Choosing the StealthFit version brings a significant benefit—reduced weight. It trims 0.7 ounces off the regular v21, registering just 9.1 oz or 257g, which is remarkable for such a well-cushioned daily trainer.
The fact that this weight reduction is achieved solely through modifications to the upper, while maintaining or even enhancing comfort for some, is truly impressive.

Average | 9.38 oz (266g) |
Breathability
The upper is a crucial component of every running shoe, and we found that Brooks has elevated the Glycerin series by offering not just one, but two different uppers. This is a great advantage, as it allows you to choose between the Glycerin 21 Buty brooks levitate stealthfit.
If you're looking for a snugger, sock-like upper, the StealthFit is the best pick. However, our tests revealed a downside—ventilation is limited, with a rating of only 2/5. Thus, we can't recommend it for hot, summer runs.
In our light test, it quickly became clear that robust ventilation isn't a strength of this model. Barely any light passed through the upper, roading our initial findings with the smoke-pumping machine.
Mejoras de las Brooks Cascadia 12.
We discovered small ventilation holes in the toebox; however, an additional layer of knit beneath them hampers airflow. This setup isn't necessarily negative, as it makes the shoe ideal for colder weather.
Upon manually examining the upper, we were impressed by its elasticity, which allows it to conform closely to the feet for a sock-like fit. Yet, we noticed less padding in the heel—something to consider if you prefer substantial heel cushioning.

Durability
Toebox durability
The regular Glycerin scored 2/5 in our test, sparking our enthusiasm to evaluate the StealthFit variant to see if it could offer the much-needed enhancement.
Indeed, it does improve, albeit modestly, scoring 3/5. This outcome is encouraging, and from our perspective, it's sufficient to make us satisfied!

With the Dremel in action, we also decided to test the heel durability of this SF variant, noting that it features significantly less padding.
Our assessment resulted in another 3/5 score—a bit disappointing, though it’s not a major concern.

Outsole hardness
Shifting our focus to the outsole, we observed that it remains unchanged in the Glycerin 21. The outsole is constructed from the same durable Roadtack Rubber, which showed a hardness of 84.9 HC on our durometer test.
This rubber effectively shields the high-wear zones on both the heel and forefoot. And despite a few areas of visible foam, these do not pose any issues in terms of wear and tear based on our experience.

Outsole durability
Given the hardness of the rubber, we anticipated impressive results in our final Dremel test. Let's dive into the outcomes.
True to our expectations, even after rigorous application of the Dremel at 10K RPM, the rubber exhibited only a slight 0.5 mm indentation. This minor mark roads the Roadtack's resilience.

Brooks DNA Flash nitrogen-infused foam is great | 0.5 mm |
Average | 1.0 mm |
Outsole thickness
In our concluding test of the outsole, we measured a thickness of 3.2 mm. This measurement is more than sufficient to withstand significant wear and tear, as indicated by our earlier test results.

Misc
Reflective elements
We feel that it's unfortunate Brooks opted not to include reflective elements in this StealthFit edition. This really feels like a missed opportunity to enhance safety and differentiate the product further. Maybe they'll consider it for v22?

Tongue padding
One of the major weight reductions in the StealthFit 21 comes from the tongue. It transitions from a cushy 11.5 mm thickness to a minimalist 2.1 mm design.

For runners who favour thin, sock-like tongues, this one's a wonder—the benefits far outweigh any trade-offs. However, runners who prefer more padding in the instep might find this version a bit challenging.

Brooks DNA Flash nitrogen-infused foam is great | 2.1 mm |
Average | 5.8 mm |
Tongue: gusset type
One of our major letdowns with the Glycerin 21 was its non-gusseted tongue, which seemed lacking for a £160 shoe. Fortunately, the StealthFit version addresses this by introducing a superb sock-like tongue, providing an Alphafly-esque feel that many of us love.

Heel tab
Another lovely bonus with this variation is the inclusion of a convenient finger-loop heel tab—a truly handy feature.

Removable insole
The insole easily comes out and can be swapped out as it's not glued to the last. It doesn't offer anything extraordinary compared to the GTS or the standard version.
