Brooks Glycerin 22

The Brooks Glycerin 22 came to my feet at a complicated time in my life as an athlete. But I think we all went through it. I was in full preparation for the Seville marathon, but not in the best physical condition. My fitness was poor, I was overweight and, if that wasn't enough, a calf injury had me very limited in my training.

However, I decided to train differently and the Glycerin 22 would help me in my process of returning to physical activity to get back to running with confidence and security.

For me, the Brooks Glycerin has always been a reference model in the category of running shoes with cushioning and comfort. I have tested several previous versions and, in fact, I spent almost all of 2023 running with them, which allowed me to complete the 100 km of road in Millau. One of the most demanding and beautiful races I have ever faced.

With this track record, my expectations for the 22nd version of the Brooks Glycerin were quite high. I expected it to keep all the qualities that had conquered me in previous versions, but with possible improvements that enhance its performance.

Cushioning technology in the Brooks Glycerin 22

One of the highlights of the Brooks Glycerin 22 is the evolution of its cushioning technology. In this new version, Brooks has opted to replace the traditional DNA LOFT v3 technology with the innovative DNA Tuned. This change has a direct impact on the running feel. Both technologies employ nitrogen infused foam, DNA LOFT v3 focuses on providing soft, balanced cushioning, while DNA Tuned tweaks the foam structure to offer a more personalized experience, with an emphasis on shock absorption in the heel and increased reactivity in the forefoot.

It may sound a bit professorial in running, I'll try to explain it better. Like the DNA LOFT v3, DNA Tuned uses nitrogen infused foam, but it is designed with different sized cells: larger in the heel for more shock absorption and smaller in the forefoot. This allows for better comfort and above all a more agile response.

Visually, the midsole presents an interesting configuration. You can notice a layer of yellow foam encapsulated within a translucent protection, which allows you to intuit how Brooks Running has worked on the distribution of materials to improve performance. This new foam not only contributes to improved comfort, but also ensures a balanced and well-cushioned ride. The combination of these elements results in a shoe that provides an extremely comfortable running experience, ideal for long distances and high volume training.

Brooks Glycerin 22 vs Brooks Glycerin 21

Comparing the Brooks Glycerin 22 to its predecessors, especially the Brooks Glycerin 20 and Brooks Glycerin 21 versions, several key performance-enhancing differences can be noticed. The most notable is the change in midsole technology that I just told you about.

But the outsole has also been redesigned. It now features a different arrangement of wear elements, which again optimizes cushioning. Materials have been removed in certain areas to lighten the shoe, although weight is one area where I think Brooks would have room for improvement. Transitions in each stride are more natural and fluid.

In addition, the upper has been completely revamped. It is much more breathable, has no seams and adapts better to the foot, avoiding possible discomfort or chafing on long runs.

As an extra, reflective elements have been added to improve visibility in low light conditions, something very useful for those who train at night.

What I liked best about the Brooks Glycerin 22

Without a doubt, there are many positive aspects to this new version of the Glycerin. Comfort and stability continue to be its strong points, making it an excellent choice for runners looking for a shoe that allows them to rack up miles without worrying about joint impact. Cushioning has been significantly improved thanks to the addition of DNA Tuned, which provides a soft feel without sacrificing energy return.

The upper also deserves a special mention. It is highly breathable, fits the foot well and offers excellent comfort even during prolonged training sessions. In addition, the incorporation of reflective elements is a detail that I really appreciated, as it provides extra safety in night workouts or with low visibility. Finally, the heel and tongue straps make the shoe fitting process much easier, a small detail that makes a difference in the day to day.

Possible points of improvement for the Brooks Glycerin 22

Despite its many advantages, there are some details that could be improved in future versions. The tongue, for example, is not attached to the sides, which can cause it to shift during a run and affect the overall fit. If Brooks fixes this minor inconvenience in future versions, the wearing experience would be even more satisfying.

Another area that could use improvement is the transition in the midfoot area. Although the stability is excellent, some runners might find the structure in this area too firm, which could make the transition in the footstrike not as smooth as in other models.

Finally, although the weight has increased, almost 50 grams to beat the 300 gram mark in a size 9.5. For a comfort and cushioning shoe it is not the heaviest, but this weight change is substantial. I understand it is due to the new midsole compound. And in the end this extra weight is offset by the shoes improved responsiveness.
