Our verdict

The Brooks Glycerin 20 GTS enhances the tried-and-true features of its neutral sibling with special consideration for overpronators. With substantial DNA LOFT v3 cushioning and a GuideRails system, it ensures a stable ride. While its cost may be on the steeper side and its weight could limit speedwork, we see it as a reliable companion for easy and moderate-paced runs.

zapatillas de running Brooks pista talla 41 | Who should NOT buy

If you're on the hunt for a lightweight yet stable running shoe, the Glycerin GTS 20 might not be your best bet based on our lab tests. Consider a lighter and more affordable option like the Saucony Tempus.

In our view, this shoe might also not be the best choice for midfoot or forefoot strikers due to its significant heel-to-toe drop. For runners who strike with this part of their foot, a flatter shoe with stability features, such as the Кроссовки brooks ghost 12, is a more reasonable choice.

Cushioning

Heel stack

Brooks took a conservative approach here, providing a generous amount of foam in the heel. They are aware that most overpronators are heel strikers who need extra cushioning in this area.

With 36.5 mm of nitrogen-infused DNA LOFT v3, there's no possibility of feeling the ground through this shoe.

zapatillas de running Brooks pista talla 41 | Midsole softness

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

DNA LOFT v3 is a nitrogen-infused midsole, making it lighter and more responsive than the standard DNA LOFT.

But don't anticipate a super-plush experience like in a Nike Invincible 3. With a softness measurement of 23.4 HA, this foam delivers a balanced, comfortable feel that's well-suited for stability-focused shoes like this one.

Following a 20 minutes exposure to freezing temperatures, the foam continues to strike a very balanced note—it's neither too soft nor too firm. Our subsequent round of measurements yielded a 28.9 HA value.

This represents a 23.5% increase, a result that aligns nicely with the average. It's precisely what we anticipate from a foam based on EVA. Things could indeed have been worse...

Torsional rigidity

Stability in any shoe necessitates at least a moderate level of torsional rigidity, and the GTS 20 confidently embodies this trait. Our assessment scores it a solid 4 out of 5, a rating that unquestionably surpasses the average result.

Heel counter stiffness

The rigidity of the heel counter plays an essential role too. Despite the potential discomfort some might feel with a firm heel counter, it becomes almost indispensable in stability-focused shoes. It helps prevent the shoe from lateral collapse, especially crucial for heel strikers.

In the GTS 20, we've discovered a built-like-a-tank 5/5 heel counter. While we might have preferred a bit more flexibility, we comprehend and support Brooks' whole-hearted commitment to this design, being their ultimate goal to ensure top-tier stability for heel strikers.

Midsole width - forefoot

An additional stability-boosting tactic often employed by brands involves expanding the shoe's landing base. Quite intuitive, isn't it?

Brooks has opted for an ultra-wide design in this case. With a forefoot width of 119.5 mm, it ranks among the widest shoes we've ever analyzed in our lab!

High torsional rigidity is almost a given for any stability shoe, but this isn't necessarily the case when it comes to stiffness. Indeed, it wouldn't make sense for a shoe designed for daily runs to be super stiff.

In alignment with this, our measurement for the 90-degree bend test came in at only 24.9N, which falls below the average result. This explains why the shoe provides such a comfortable ride during easy aerobic runs.

Weight

A significant disappointment with this shoe is its excessive weight. The scale reveals a 10.9 oz (309g) reality for a US size 9—just too much by contemporary standards.

We are eagerly looking to the next release, hoping that Brooks will take the necessary steps to bring this shoe's weight under the 10 oz benchmark.

Breathability

Even though the engineered mesh upper that Brooks incorporates doesn't offer the ultimate ventilation, we gave it a respectable 4/5 in our breathability test. 

The results show that even in warmer climates, the shoe maintains its cool. Yet an added advantage of not being overly breathable is that it can keep your feet warm during winter when paired with thick socks.

Upon testing with light, it's clear that Brooks prioritized ventilation in the toe box. This strategy is one of the most effective for maintaining good airflow and ensuring adequate ventilation.

Durability

Toebox durability

Our initial impressions of a shoe often come from the feel of it in our hands, before we even start the tests.

For the Glycerin 20 GTS, it was evident early on that the upper might not be sturdy at all. Of course, we always hold out hope that we might be surprised.

Regrettably, our concerns were confirmed once we the Dremel met the upper. The engineered mesh from Brooks couldn't withstand the pressure—it disintegrated instantly.

With such disappointing results, we had no option but to assign the Glycerin 20 GTS a score of 1/5.

Tongue padding

Brooks designers likely decided a gusset wasn't necessary for the tongue because of its massive padding. With a thickness of 9.9 mm, it's like a pillow for your instep, enhancing a snug lockdown.
