We analyze Adidas UltraBoost, Asics Nimbus 21, and Brooks Glycerin 16. Which one will you choose?

Three aces, three emblems, the three "pretty girls." In short, three fantastic running shoes, each with its charm and differences that make them unique and yet almost equivalent.

Choosing a running shoe involves significant analysis and selection, model comparison, technology analysis, and product testing, among other things. The major running shoe brands strive to outdo themselves with each new model and to surprise both runners and the competition.

Pay attention to this comparison of the most in-demand new running products on the market. It's no surprise that when comparing top-of-the-line running shoes, doubts arise. Today, we're going to analyze the differences and advantages of 3 star running models: Adidas UltraBoost, Asics Nimbus 21, and Brooks Glycerin 16.

What's good about the ASICS NIMBUS 21

Cushioning and Firmness. Of the Asics Nimbus 21, we can say that the "tank" is no longer such a "tank." At first glance, we highlight its last, a bit wider than the previous one (making it ideal for those who use orthotics). However, it still maintains an amazing fit. The biggest change from its previous version comes in the cushioning, with the Gel placed a bit differently. Specifically, in this new edition, the gel is not found on the outer edge of the midsole; instead, Asics has varied and angled it.

With this, we get even more cushioning, if possible. Its weight is 315g; it has been further lightened compared to its predecessor. The drop is 10mm (23mm heel and 13mm forefoot) to provide a sensation closer to the ground and more reactivity in each stride.

With the introduction of the incredible MetaRun, there was a slight doubt about the Nimbus, but it has now become clear that it remains the "star" of the Japanese brand, and they are doing everything to make it even better. The upper is completely heat-sealed, with no seams.

In short, if you want security, joint protection, and a firm cushion feeling under your feet, here's the answer: Asics Nimbus 21.

"If you want security, to protect your joints, and a firm cushion feeling under your feet, here's the answer: NIMBUS 20"

Why choose the BROOKS GLYCERIN 16

To talk about Glycerin is to talk about a "sure bet": robustness without losing sight of an excellent stride transition, so characteristic of the American brand. Who would have thought a few years ago that we would see runners' feet populated by this model, which at first was met with more rejection than acceptance, and which, little by little and without much fanfare, but with much substance ;).

It has become an indispensable shoe in the running scene. To the point that the magnificent Valencia Marathon had its own "Glycerin 14." (a model adorned with Valencian motifs such as paella, horchata, oranges, etc.).

Regarding its predecessor and technologies, this shoe maintains the highly successful SuperDNA in the midsole and adds the Rounded Heel as a major new feature. This provides a more rounded heel to give that extra stability needed for heavier runners.

As for the drop, Brooks maintains 10mm for this model; highly appreciated for better stride response and with a weight of 337g, it remains in line with "lightening but without losing substance," a goal sought by all.

Advantages of the ADIDAS ULTRA BOOST

Boost taken to the highest power, never better said. An extremely reactive shoe but with the softest feel on the market by far, that "cushion" that makes many feel like they are running barefoot.

The Primeknit upper: interwoven fibers that provide a perfect fit yet offer that much-needed freedom of movement. We describe it as "a sock made into a shoe."

The midsole is maximized with Boost. For those who want to log many kilometers at a relaxed pace, this is a true travel companion. If we demand performance, it will respond wonderfully with that quick rebound effect that Boost users are already familiar with. The Torsion System is essential for providing the necessary stability.

A significant and, I would say, mandatory new feature in Adidas's most technical model, compared to the previous UltraBoost, is the introduction of the Continental compound. We all wondered why the original UltraBoost didn't use it, but Adidas corrected it—as wise people do—and this version now offers the perfect grip provided by Continental rubber.

We also highlight as an improved novelty the sanding on its 92 contact lugs on the sole, which, in the first version, did not perform as expected in wet conditions. This is another major plus in these new shoes. A 10mm drop (27mm heel and 17mm forefoot) and a weight of 305 grams provide sufficient lightness for a shoe specifically made for many comfortable kilometers.
