The Brooks Running Glycerin line has been one of the reference models for all runners with neutral footstep, intermediate weights and for running at a wide variety of paces for several years now. It is certainly one of the silhouettes that best represents the philosophy of the American brand: happy running. Now that feeling is maximized with the arrival on the market of the renewed Brooks Glycerin 21

In RUNNEA we present you all the details of one of the most valued running shoes on the market. The Brooks Glycerin 21 represents a very noticeable change from previous editions, but without losing its perspective of offering maximum comfort and maximum protection in each stride.

Main characteristics of the Brooks Glycerin 21

With that hallmark of offering maximum comfort and protection, these new running shoes from Brooks, the new update of the Glycerin 21, will implement very notable and important new features with respect to its previous edition of the Brooks Glycerin 20

Interesting changes can be seen in the midsole geometry with an increased height of its profile. Thanks to its exclusive DNA Loft v3 foam, the model gains in softness and comfort, without losing a bit of stability. The purpose is none other than for the runner to enjoy a smoother, more stable, lighter and more responsive stride. Of course, the model is one of the most comfortable that you can buy in the running shoes market.

Both the upper and outsole also bring with them some changes to improve support and fit, as well as more efficient traction on different surfaces.

Ideal Brooks Glycerin 21 runner

Despite all the changes to these Glycerin 21, the Brooks Running staff has not changed their strategy with this model, and this twenty-first edition of the Glycerin remains the model that every runner is looking for for their daily workouts over all kinds of distances and for different running paces, from 4:30 min/km, and even lower. A set that maintains its classic 10 millimeters of drop.

Thus, the maxim of the Brooks Glycerin 21 will maintain its essence of running comfortably, without worries, and without looking at the time.

Technical specifications of the Brooks Glycerin 21

Some of the most important technical details of the new Brooks model for asphalt Glycerin 21 can be found in its midsole. With the incorporation of the DNA Loft v3 foam, Brooks bets for a lighter and more dynamic model, but that manages to maintain its comfort and softness in the tread. As if that were not enough, the fit of its upper is noticeable, also coming with up to 59.7 of recycled materials.

For its part, we speak of these running shoes for men and women as one of the models that are sure to make waves in the Brooks catalog and in the market, which maintain a reduced weight of only 277 grams and a total drop of 10 millimeters.

Comparison: Brooks Glycerin 21 vs Brooks Glycerin 20

The Brooks Glycerin 21 introduces several significant improvements over its predecessor Glycerin 20, with the goal of providing a more comfortable and efficient running experience. One of the main new features is the updated DNA LOFT cushioning technology , which now encompasses the entire midsole, offering enhanced softness and shock absorption with every step. In addition, the upper has been redesigned with a more advanced mesh material that improves breathability and fit, adapting better to the shape of the foot and providing a more comfortable and secure feel.

The Glycerin 20, on the other hand, while still high-quality shoes, do not incorporate these advanced improvements. The DNA LOFT cushioning, while present, does not extend throughout the midsole as it does in the newer model, which may translate into a less even cushioning experience. Overall we can say that the Brooks Glycerin 21 is a notable evolution in the line, providing an improvement in comfort and performance that is especially beneficial for runners looking for a softer ride and a more adaptive fit.

Review of Brooks Glycerin 21

22 April 2024

Brooks Glycerin 21, it has everything to maximize your long distance running experience.

My analysis of the recently launched Brooks Glycerin 21 began with my debut at the 2024 Mitja Marató Barcelona. The results? Exceptionally positive and fulfilling.

In Barcelona, my aim wasn’t to set records but to finish the 21k with superb running sensations—a mission accomplished with the Brooks Glycerin 21 running shoes

First sensations of the Brooks Glycerin 21

The Glycerin 21, as suggested by its name, is the 21st iteration of this standout American model. It signifies more than two decades of continuous improvement, underscoring the shoe's longstanding appeal and success.

Brooks has been creating, working on and improving the Glycerin concept for more than 21 years. And it's been more than 21 years that this shoe first found its audience, otherwise, obviously, it would not have achieved this longevity.

Brooks Glycerin 21 runner profile

Now let's get into the actual test of these Glycerin 21 from Brooks Running.

Firstly, to answer the obvious question: "What is Glycerin?" The hallmark of the Glycerin range is its exceptional balance of cushioning and comfort.

Regarding the runner profile, one of the standout features of the Glycerin 21 is its suitability for a broad spectrum of runners. It's particularly well-suited for those with a neutral gait, aiming for a versatile shoe that performs well in both training and competitive long-distance events like marathons.

What I liked the most about the Brooks Glycerin 21

Foremost, the shoes provide superb cushioning and comfort with every mile. This version, the Glycerin 21, features the premium DNA Loft 3 compound, which excels in shock absorption while maintaining responsiveness.

From my perspective as both a runner and a reviewer, it's clear that these shoes are perfectly tailored for the everyday runner tackling a half or full marathon.

It's impossible to overlook the improvements in this model. The midsole is bulkier yet lighter than previous versions, enhancing the experience at the Mitja Marató Barcelona 2024 with its lightness and responsive cushioning. Running has never been more enjoyable with the mantra "RUN HAPPY" in the Brooks Glycerin 21!

Another positive aspect of the Glycerin 21 is the durability of its outsole. After 10 weeks of training, the shoes are just beginning to show signs of wear. The strategically placed durable rubber pieces not only ensure optimal grip but also enhance stability compared to the Brooks Glycerin 20.

The heel area is robustly protected; it maintains a traditional design in this area, sticking to a tried-and-true approach. The upper is made from a generous, elastic fabric that conforms well to the foot’s shape, offering ample ventilation through tiny gaps.

Brooks Glycerin 21: improvement opportunities

Despite my affiliation with the RUNNEA TEAM, I must candidly suggest that Brooks Running should hesitate before releasing a new version. The Brooks Glycerin 21 has achieved such a refined balance of features that it might just be the best iteration ever designed.

As it stands, there are few, if any, significant areas for improvement.
