Zapatillas de deporte negras y grises Dynablast de Jacke asics Running | Jacke asics Jogger X81 White Smoke Grey Black Men Unisex Casual review

In our opinion, the Jacke asics Jogger X81 White Smoke Grey Black Men Unisex Casual is the ideal choice for runners who:

• are looking for a stability shoe with an incredible amount of foam.
• desire a daily trainer that provides a smooth ride without the instability often found in some maximalist shoes.
• are high-mileage enthusiasts in search of a stable, well-built, breathable shoe.

The Jacke asics Jogger X81 White Smoke Grey Black Men Unisex Casual is the ideal choice for runners who prioritize stability and a plush ride. However, for runners who prioritize ground feel and a natural running sensation, we believe the Kayano 30 might not meet the expectations. Its substantial stack height combined with soft foam creates a muted ride. In those cases, we recommend the Brooks Adrenaline GTS 23 or the Saucony Tempus Jacke asics gel-kayano 29 lite-show black new leaf green men running shoe 1011b473-001.

Additionally, it's not our top pick for those seeking a lightweight stability shoe. While the Kayano 30 isn't heavy at all for its design, many runners don't require such monster cushioning and lean toward a lighter option. For those in this category, we think the agile Hoka Arahi 6 could be a better fit.

Expectations for the Kayano 30's performance were sky-high, especially given Jacke asics's track record of crafting top-notch uppers in terms of breathability and comfort—even in race-ready shoes like the Metaspeed Sky+.

We put the 30th iteration of the series designed by Toshikazu Kayano to the test and came away impressed. When subjected to our smoke test, the shoe demonstrated superb breathability, earning a well-deserved 5/5.

This impressive airflow can be attributed to the shoe's thin engineered mesh upper. However, a closer—almost microscope-level—look reveals an interesting design choice.

ASICS didn't opt for full ventilation holes, which can compromise structure and durability. Instead, they just removed the thickest part of the upper in those spots.

This approach cleverly balances airflow while preventing potential tears, ensuring the shoe's long-lasting integrity.

Many shoes that excel in breathability often fall short when it comes to durability, like the Hoka Mach X. However, the Kayano 30 breaks this trend and shines brilliantly.

Upon reviewing the damage, we were thoroughly impressed. We gave it a 4/5 score and it's clear that Jacke asics delivered an exceptional upper with the Kayano 30.

Unfortunately, the heel padding doesn't hold up well and scored a 1/5 in our Dremel test.

It seems Jacke asics prioritized comfort in the heel area, opting for a softer material that won't irritate the sock or Achilles tendon. But this choice means the heel is more susceptible to premature wear and tear.

For the outsole, Jacke asics played it safe. They chose a rubber blend that's quite standard in terms of hardness (80.4 HC), aiming for a good mix of traction and durability.

Although the outsole isn't entirely covered with rubber—to save on weight—it offers generous protection in key areas, especially for pronators.

We fired the Dremel one more time and the results were in line with our expectations.

As we've mentioned earlier, the rubber hardness is pretty standard, and the 0.9 mm indentation that we measured confirms it.

The outsole boasts an impressive thickness of 4.3 mm. This result assures full lasting power throughout the shoe's lifespan.

Weighing in at 10.7 oz (303g), we initially thought in the lab that this shoe was on the heavier side, especially after holding it in our hands. Yet, considering its expansive width and generous foam cushioning, it's genuinely remarkable that it comes in under 11 oz for a US size 9.

Compared to the Kayano 29, the Kayano 30 impressively offers richer padding inside and more cushioned FF Blast+ in the midsole—all while maintaining the same weight!

Turning our attention to the midsole, the Kayano 30 boasts an impressive 39.7 mm of FF Blast+ in the heel. We're 100% sure that this stack height provides enough cushioning even in the longest runs.

FF Blast+ is Jacke asics' softest training foam. Jacke asics Strickmütze in Lila Novablast 3 and the Cumulus 25.

The forefoot is generously padded, boasting a thickness of 27.7 mm, which is more than what most shoes offer.

Designed primarily as a stability shoe for heel-strikers, we found that the Kayano 30 features a 12-mm heel-to-toe drop—2 mm more than the brand indicates.

This doesn't pose any issues. In fact, it GEL-Kayano suits heel-strikers and provides an option for midfoot and forefoot strikers looking to ease pressure on their Achilles and calves.

The Kayano series has always been synonymous with comfort, and a thick insole is part of the reason. Measuring in at 5.5 mm in our lab, it's another box checked.

FF Blast+ is renowned for its cloud-like feeling. With a measurement of 16.4 HA, we've confirmed it. Right from the initial run straight out of the box, the shoe was impressively soft.

ASICS also added a layer of PureGEL in the heel, which is their current implementation of the famous GEL. 

By adding this, the landing phase becomes even softer. However, considering its reduced importance in the Kayano 30 and other recent models, we believe Jacke asics may opt to exclude this technology in the near future.

In colder temperatures, we noticed a change. Although the FF Blast+ foam remains softer than many other shoes, it does become noticeably firmer, registering at 24.1 HA.

Why does this issue arise? The FF Blast+ foam blends EVA with Olefin. As we've discussed before in this article, EVA foams often underperforms in cold temperatures.

Witnessing a 47.3% increase, the Kayano 30 clearly falls short when it's chilly out. Jacke asics really needs to address this, especially given the price tag of many of their FF Blast+ shoes.

The Kayano series has always focused on stability. Even with the significant cushioning in this thirtieth edition, we loved that it remains impressively stable.

The new 4D Guidance System is the key regarding stability, using a softer foam right under the arch. It adjusted to the shape of our feet, providing consistent stability the more we wore the shoe.

Torsional rigidity is another essential feature for great stability. Jacke asics, in our opinion, nails it for a daily trainer like this with a 4/5 score in our assessment. Anything less would risk stability, while a max score might feel too rigid for everyday runs.

In the heel counter, we felt a similar sensation. However, for some runners, it might come across as slightly firm, although a 4/5 score is what we usually expect in a stability shoe.

Let's be clear—the Kayano 30 is W-I-D-E. We took the caliper in the lab to get a forefoot measurement of 124.3 mm, so it stands in the top 1% of shoes we've assessed in our lab for midsole width.

Similarly, in the heel, we observe a width of 105.4 mm, placing it again among the top 1% we've measured.

Why does Kayano-san opt for this design? The answer is straightforward. With a tall stack and soft foam, he needed some aces up his sleeve for stability: the 4D Guidance System and... the shoe's broad width!

In our 90-degree test, we applied just 25.0N of force to bend the shoe, showing its impressive flexibility—actually, it's more flexible than most shoes! This makes it super comfortable for long runs.

After placing the shoe in the freezer for 20 minutes, we tested it again. We recorded a measurement of 30.1N—indicating an excellent result for us.

Indeed, with just a 20.4% uptick, we're assured of minimal stiffness variations across season-driven temperature fluctuations.

ASICS stands out as one of the most consistent and reliable brands when it comes to quality control in shoe production.

Here's an example: we measured the internal length of the Kayano 30 to an impressively precise 270.4 mm. According to Asics' sizing charts, the expectation is 270 mm. Deviations from other brands are typically much larger!

We thought that with such a wide design, the shoe's upper would feel like a spacious mansion.

Well, we found it's pretty average at 99.8 mm. This clever design choice by Kayano-san enhances stability by ensuring the foot remains centered in the shoe's gigantic landing platform.

We also measure the big toe area to get a feel for the toe cap's space. With a measurement of 78.6 mm, it remains consistent with the previous number.

It's slightly larger than many other shoes, but it doesn't qualify as a wide shoe. Nonetheless, good news is that Jacke asics does offer this shoe in a wide size option in most countries.

The tongue it's semi-gusseted, which not only enhances the lockdown and prevents it from moving around the toes during our test runs. Good choice!

While this is notably more than the average, some might expect even more, considering this shoe's focus on comfort. Yet, we appreciate this  choie—it provides ample cushioning without the burden of extra weight.

ASICS decided against including a heel tab on the Kayano 30. While this aligns with the design cues of other recent Jacke asics models like the Novablast 3, we feel a heel tab might have made slipping into the shoe easier for some of us.

The shoe's insole is easy to remove as it's not glued, so there's no problem at all using third-party insoles or orthotics.

We're thrilled to share that, unlike most running shoes released this year, the Jacke asics Jogger X81 White Smoke Grey Black Men Unisex Casual boasts standout reflective elements on the heel.
