Brooks Hyperion Max 2: análisis y review

We've discovered in the lab that the Hyperion Max 2 is an outstanding choice for:

• Fans of the Brooks Hyperion Elite 4 seeking a dependable training companion for long runs and speed training, as it features the same midsole technology and offers a similar ride.
• Midfoot and forefoot strikers in search of a stable shoe versatile enough for everything from easy long runs to intense interval workouts.
• Runners who prefer a plated shoe but want to steer clear of max-stacked models and carbon plates, finding this option more grounded and flexible.

We found that the Hyperion Max 2 has undergone significant changes from its predecessor—however, not all modifications have proven beneficial. In our experience, the shoe has gained too much weight, which might not appeal to everyone, particularly those looking for lighter speed trainers like the Saucony Endorphin Speed 4.

Additionally, at a price point of €200, we believe a top-tier foam should be expected, yet the DNA Flash v2 does not meet this criteria for us. For runners seeking the ultimate in energy return within a performance trainer, we suggest alternatives like the ASICS Superblast 2 or the PUMA Deviate Nitro 3.

To kickstart the lab review of the Hyperion Max 2, we turned on our smoke-pumping machine to evaluate the airflow through the engineered mesh upper, which initially appeared well-ventilated based on its materials and design.

However, breathability fell slightly short of our expectations. While not a poor result, we noticed that airflow became somewhat restricted after a few seconds, resulting in a decent 3/5 rating from us.

After completing the smoke test, we continued with our series of evaluations to further analyze the upper. First, we shone a light through the upper to compare variations in thickness and ventilation. Brooks excelled by enhancing the toebox area while simultaneously structuring the sides of the upper for increased stability.

Regarding the toebox, we used our microscope to investigate the cause of the reduced airflow, noting that its predecessor scored a higher 5/5.

Previously, the ventilation holes were unobstructed, but now, Brooks has added a secondary layer beneath the top one, which impedes airflow.

Overall, this upper is quite good, though a bit more ventilation would have been ideal. Nonetheless, it performs adequately in nearly all temperatures, except in extremely hot conditions.

Every downgrade often has its side benefits, and that proved true in our toebox durability test. 

We employed our standard method using a Dremel at 5K RPM and 3.2N of force. And we discovered a noticeable improvement over the first-generation Hyperion Max, as the dual-layered upper increased durability to a solid 3/5 rating.

We continued using our setup with the Dremel to test the heel padding, which is notably plush and comfortable for a speed-training shoe.

We were pleased to discover that this model has improved from the first version, scoring a decent 3/5. While there's room for improvement, we are satisfied with this performance for now.

After noting slow but steady progress in our previous two durability tests, we shifted focus to the outsole, which boasts extensive rubber coverage for being a performance trainer.

We discovered, however, that the rubber Brooks uses is relatively soft, rated at 72.0 HC, potentially impacting its durability. But, of course, here at RunRepeat, we have a specific test for that!

Concerned about the potential for early wear due to the softer rubber, we performed one additional test with the Dremel.

We were happy with the results—after completing the test, we found only a minor indentation of 0.8 mm. That's way better than what we expected with such a soft rubber.

To ensure greater durability, we discovered that Brooks did not skimp on the outsole thickness, adding 3.0 mm to prolong the life of the Hyperion Max 2. 

In fact, given that this is a shoe designed for fast running where weight is crucial, we think they could potentially trim down 0.5 or 1 mm in future versions.

Brooks has traditionally aimed for lightweight designs in the Hyperion lineup, and the first-generation Hyperion Max was impressively light at just 7.5 oz or 213g. That's why we were quite surprised by the heft of the v2 when we first held it in the lab.

At 9.2 oz or 262g, it's not that bad, of course. However, compared to many speed training shoes and especially its predecessor, it's clear that Brooks has room for improvement. Despite the added comfort, cushioning, and inclusion of a plate in the new version, we think that the weight gain it's excessive.

One of the reasons for the weight increase in the HM2 is its midsole.

We used calipers to measure 33.2 mm in the heel area, which is a slight increase not due to additional foam, but because of the inclusion of the nylon plate.

The forefoot has gained 2.2 mm from last year's version, totaling 26.4 mm, which benefits midfoot and especially forefoot strikers. However, as we previously noted, this increase largely results from the inclusion of the plate rather than the DNA Flash v2 foam itself.

The difference between the forefoot and heel results in a 6.8-mm drop, which attracts a wide range of runners, particularly benefiting those who are midfoot and forefoot strikers.

For those accustomed to the regular Hyperion with its steep 12.3-mm drop, this offset might seem unusual. And some of you maybe were wondering if the Max variant maintains the same design path—well, the answer is clearly no.

According to measurements from our calipers, the Hyperion’s midsole thickness is only 2.8 mm, which is thinner than that of the typical shoe.

Now, let's explore the midsole of the Hyperion Max 2, always a highlight of our lab reviews. This version introduces the same DNA Flash v2 foam that debuted in the Hyperion Elite 4 and a novel configuration featuring two distinct foam layers encasing a nylon plate.

The primary DNA Flash v2 layer is positioned directly above the plate, just beneath our feet. We measured its softness at 20.9 HA, nearly identical to the first generation—it's certainly not pillowy, but not overly firm either.

This nitrogen-injected EVA foam surpasses traditional EVA in energy return and weight reduction, thanks to its internal bubbles. However, despite these advancements, it doesn't match the performance of elite superfoams like ZoomX or FF Turbo+, remaining a step behind the market leaders.

While the first-generation Hyperion Max had a single foam layer, the new model boasts two. The additional layer sits beneath the plate and compresses against the ground, offering a softer and more plush feel compared to its predecessor.

To verify our impressions, we pressed our durometer against this secondary layer and recorded a softer measurement of 17.6 HA.

To evaluate the Hyperion's performance in cold conditions, we froze the shoe for 20 minutes and then measured its softness again. The post-freezing test revealed a minor 18.5% change in performance, which is a good outcome for an EVA-based foam.

The most significant update in the Hyperion Max 2 from its predecessor is the addition of a full-length nylon plate in the midsole. We found that this change significantly impacts running performance. 

Although it's not made of carbon fiber, the Speedvault plate adds some stiffness and support, enhancing the compression of the lower foam layer. However, don't expect the aggressive ride found in shoes like the Nike Vaporfly 3, as the plate here is flatter, designed more for stability than speed.

Given its high stack of foam and moderate heel-to-toe drop, it was nearly essential for Brooks to incorporate a pronounced toe spring in the forefoot to smooth transitions—and fortunately, they did.

The heel also features a subtle late-stage rocker (nothing crazy like the Hoka Cielo X1), which indicates that this shoe is better suited for midfoot or forefoot strikers.

For those seeking a stable training partner for fast paces, the Hyperion Max 2 delivers. It features a lower drop and large midsole sidewalls divided into two sections, along with the Speedvault plate and a central groove in the outsole.

We discovered that this combination provides a stable ride for neutral runners and also serves as a solid choice for mild pronators with a forefoot or midfoot striking technique.

From the moment we unboxed and tested the shoe, we noticed it was significantly more rigid than its predecessor, with its rigidity score jumping from 2/5 to 4/5. This increase in stiffness is understandable, as the first version lacked any kind of plate, whereas this second edition incorporates a Speedvault nylon plate.

The heel counter (3/5) features a small cardboard piece, providing a balance of rigidity that is noticeable without being excessive, being very similar to daily trainers. In our tests, we discovered that it offers both comfort and a secure fit for long runs.

While the inclusion of the plate in the Hyperion Max 2 has reduced its natural flexibility, fans of the original's agility and nimbleness will be pleased to know that Brooks at least has maintained controlled dimensions.

Despite the trend of increasingly wider running shoes, the Hyperion Max 2 remains modest in width, offering an alternative from most performance trainers. We measured the forefoot at 114.0 mm, which aligns closely with the average.

In our lateral stability test, we noted that this shoe excels for forefoot and midfoot strikers but falls short for rearfoot strikers, and one big reason for that is its narrow 86.4-mm heel width.

However, those needing even slight stability might benefit from trying a similar shoe with a wider heel, such as the Hoka Mach X.

In our previous discussions about the plate in this lab review, we mentioned that the shoe felt stiffer during our runs, but we hadn't yet quantified this observation. After conducting a 90-degree bend test, we discovered that the Hyperion Max 2 required 29.6N of force to bend, compared to just 25.8N for its predecessor.

The minimal difference stems from the plate being made of plastic rather than carbon fiber. Had it been carbon fiber, we would have needed over 40N to achieve the same bend in this test.

Fortunately, we discovered that after an additional 20 minutes in the freezer, the Hyperion Max 2 only increased in stiffness by 17%, which is a favorable result.

One of the challenges for some runners—and an advantage for others—was the snug, race-like toebox of the original Hyperion Max. We can confirm that the fit remains nearly identical; we measured 96.3 mm at the widest part of the toebox, just 0.2 mm wider than the first version.

Regarding vertical volume, we encountered no issues and discovered ample space for the toes, so we give the green light on this aspect.

While the fit remains snug overall, we were delighted to discover that there is now more room for toes to wiggle, with a measurement of 79.5 mm in the big toe area.

This extra space in the toebox is a treat for runners planning to use this shoe for long runs.

The Hyperion Max's lack of a gusseted tongue was a significant oversight for a premium-priced running shoe. Fortunately, Brooks has heard the running community and rectified this in the latest update, introducing a perfectly executed semi-gusseted tongue that enhances both fit and comfort.

Brooks knew they had a problem with the weight of the Hyperion Max 2, and the tongue received significant slimming, now just 1.9 mm thick compared to the previous 5.4 mm. This transforms it from the tongue of an average daily trainer to that of a racer.

While not everyone might be thrilled with this change, we appreciate it in a performance trainer. We also discovered that Brooks chose not to include typical laces, opting instead for textured laces similar to those on the Nike Alphafly 3—a nice touch that helps justify the price increase.

Brooks rarely uses finger-loop heel tabs, only incorporating them in some trail shoes like the Cascadia 17. In this model, however, they have extended the heel collar to facilitate grabbing it when necessary.

If you're looking to tweak your Hyperion Max 2 with personal orthotics or alternate insoles, the Hyperion Max 2 makes it easy. We discovered that the insole is not glued to the last, allowing for third party orthotics.

It appears to us that Brooks has yet again missed the mark for night runners, as our tests revealed that the shoe lacks any reflective features.
