Our verdict

The zapatillas de running Brooks neutro amortiguación media talla 36.5 rosas is a robust and well-constructed daily trainer, ideal for those requiring moderate stability. It's extremely cushioned, comfortable, and supportive, with an outsole that lasts forever. However, we also noticed that the upper tends to run warm and the shoe doesn’t perform well at faster speeds, limiting its versatility across different weather conditions or paces. Despite these issues, we think it's still an exceptional pick for those seeking some support without committing to a full stability model.

zapatillas de running Brooks mujer 10k talla 43 | Who should buy

  • Runners who desire a daily trainer that provides fantastic stability without the clunkiness or extra weight typically associated with such features.

Who should NOT buy

Brooks has done a fantastic job with this shoe, but we've found in the lab that it has certain drawbacks, particularly its weight. For instance, shoes like the Brooks Calçat home Casual and the zapatillas de running Brooks 10k talla 35.5 verdes, which we also tested here in the lab, are be better options if you're not looking for a max-stack shoe.

Additionally, we do not recommend this model for most runners with a forefoot striking technique due to its high drop. We suggest the Saucony Tempus as an alternative with less heel-to-toe drop, which we think could better suit that running style.

Cushioning

Heel stack

In the heel, we measured 37.2mm following World Athletics guidelines, firmly positioning the Glycerin as a max-stack, mild-stability running shoe.

While this might initially spark concerns about getting proper support, we can confidently say it does a great job—it's impressively cushioned and remarkably stable.

Our measurements showed the forefoot thickness at 26.5 mm.

Although this dimension offers a closer feel to the ground compared to the thicker heel, it still delivers generous cushioning for forefoot and midfoot strikers.

Drop

The gap between the two prior measurements results in an actual 10.7-mm drop, which nearly matches the official 10-mm drop claimed by Brooks.

By the way, if you're curious about why there are often discrepancies between our findings and the brands' claims, we offer a detailed guide that fully explores this topic.

Midsole softness

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

One aspect Brooks could have considered tweaking in this GTS version is the foam. However, we found that it remains unchanged, featuring the same foam that is used throughout the Glycerin series. From our perspective, opting for a slightly firmer compound could have enhanced stability even more for this model.

Consequently, we discovered that the GTS version continues to use the nitrogen-infused EVA known as DNA Loft v3 (20.9 HA). It's a reliable foam that offers rojas energy return and pop for everyday running.

Rocker

The Glycerin saga has consistently delivered a natural-ride, barely-rockered running experience, and we've observed that it continues this tradition. We consider this a triumph, as it preserves the shoe's core DNA.

Toebox width - widest part

After creating a gel mould of the toebox, we discovered that it's on the spacious side at 97.3 mm, comfortably accommodating even slightly wider feet.

Additionally, Brooks offers the Glycerin GTS 21 in wide (2E) sizes in most countries, ensuring that those with broader feet can also enjoy the mild stability this version provides.

Unlike the Ghost 16 and brooks bedlam review from Brooks, this toebox doesn’t taper as much, providing a bit more room for the toes. Based on our test, this average measurement of 74.0 mm delivers a well-balanced fit.

Stability

Lateral stability test

The "GTS" in the shoe's name stands for "Go To Support," and indeed, support is where this shoe truly excels.

zapatillas de running Brooks neutro amortiguación media talla 36.5 rosas Go To Support

It's important to note that Brooks doesn't market this as a stability shoe for severe overpronators, but rather as a hybrid—somewhere between a robust stability shoe Brooks Løpesko Revel 5.

It's exceptionally effective for runners with moderate stability needs, subtly enhancing gait correction and promoting a smoother stride without being obtrusive.

Torsional rigidity

One standout feature when comparing the GTS with the regular edition is its enhanced torsional rigidity, crucial for its mild-stability role.

We scored this feature a robust 4 out of 5, which is significantly higher compared to the standard model's 2 out of 5. This difference highlights the GTS version's focus on providing more support over a flexible ride.

Midsole width - forefoot

Although the GTS version introduces some changes in rigidity and the outsole, the midsole dimensions are consistent with the neutral version.

We measured 117.3 mm in the widest part of the forefoot, providing stable support that benefits forefoot and midfoot strikers, especially during sharp turns.

The heel reveals a similar story—we encountered the same large silhouette found in the neutral daily trainer, measuring a significant 100.2 mm.

This dimension fits well within the expectations for a mild-stability running shoe, although it's notably large for a neutral trainer. It appears to us that Brooks opted to standardise the sole across both models, but using the GTS version as a foundational blueprint.

Flexibility / Stiffness

Initially, we were concerned about the GTS's torsional rigidity, but our worries were alleviated after conducting our 90-degree bend test.

The force gauge registered only 23.4N—a relatively low measurement that reassures us of its inherent flexibility. This confirms that the GTS is still suitable as a comfortable daily trainer, ideal for easy paces or even casual walking with your dog.

Weight

Despite weighing 10.6 oz (301g), we were quite pleased with the outcome, as it's only 0.8 ounces heavier than the standard version.

Given the additional rubber in the heel, the GuideRails system, and the reinforced heel counter, the slight increase in weight is quite reasonable!

Breathability

zapatillas de running Brooks mujer 10k talla 43 Glycerin 21, the go-to model for neutral runners. This includes the upper's warp knit material which, unfortunately, does not excel in breathability.

After our evaluations, we assigned it a modest 3 out of 5 rating. While not terrible, it definitely shows potential for improvement, particularly for those seeking a shoe for hot weather runs.

When we shone a powerful light through the sliced upper, the near absence of light passing through highlights the limited ventilation.

zapatillas de running Brooks neutro amortiguación media talla 36.5 rosas microscope

Delving deeper, we examined the knit upper under our microscope and noted a very dense material with barely any ventilation holes—just tiny spaces that don't allow much air to flow through.

zapatillas de running Brooks neutro amortiguación media talla 36.5 rosas upper

Despite these shortcomings, the thick upper does contribute positively to comfort, a quality we confirmed through hands-on testing.

Similarly, we were pleased to find substantial padding in both the tongue and heel, consistent with the neutral version of this model.

Durability

Toebox durability

Our initial test using the Dremel on the GTS 21 focused on assessing the toebox's durability. We awarded it a modest score of 3 out of 5, which is a positive result, especially for a knit upper.

We're quite satisfied with this, considering the Glycerin's luxuriously plush upper. This performance confirms our belief that the shoe offers decent resilience, especially given the softness of its materials.

Outsole hardness

We turned the shoe over to examine the outsole closely, starting with the hardness of the Roadtack Rubber. The GTS variant, designed specifically for mild-stability runners, includes additional coverage in the midfoot to mitigate wear from overpronation.

In our final Dremel test, we doubled the speed to 10K RPM to challenge the Roadtack Rubber outsole of the Glycerin GTS 21 more aggressively.

Remarkably, the rubber of the Glycerin GTS 21 has proven itself to be exceptionally resilient. Despite the intensified testing, we noted only a slight indentation of 0.5 mm. That's an A++ in our books.

Misc

Reflective elements

It came as a letdown to find out that the Glycerin 21 GTS lacks any reflective elements, much like its non-GTS counterpart. We are convinced that incorporating reflective details could significantly benefit runners who prefer late-evening or early-morning runs.

Tongue padding

The tongue of the Glycerin GTS 21 is well-cushioned, featuring a plush, pillow-like main foam surrounded by a slimmer layer.

zapatillas de running Brooks neutro amortiguación media talla 36.5 rosas laces
The lacing system is straightforward and functional, exactly what you'd expect from a daily trainer, free from any unnecessary additions or complicated designs.

We measured the padding at an impressive 11.5 mm! While we think this might be a bit excessive for some and could be used to shed some weight, we can confirm that it offers exceptional comfort.
