Our verdict

The ASICS Gel Kinsei Max is massive, comfort-loaded, and unapologetically heavy. In our runs, it felt more like a lifestyle-performance hybrid than a solid daily trainer. We were surprised by its colossal GEL piece in the heel, which offered cloud-plush landings, but we think that the high weight and steep price tag make it a hard sell. In our opinion, it’s best suited for casual runners who want a bold-looking, comfortable option and don’t mind the extra heft underfoot.

Pros

  • Deep, plush cushioning
  • Rocker geometry for smooth transitions

  • High-quality upper
  • Ideal for heel strikers
  • Can be used as a sneaker or travel shoe

Cons

Who should buy

The ASICS Gel Kinsei Max is a solid pick for:

  • Loyal fans of ASICS' old-school GEL tech eager to enjoy it again in a premium daily trainer.  
  • Those seeking a comfort-focused shoe for jogging, walking, travel, and light workouts—packed with a towering stack for extra underfoot cushion.
  • Casual runners with a generous budget who land on their heels and prioritize comfort.

Who should NOT buy

We believe that the substantial weight of this shoe, detracts from its appeal as a modern running option. For those prioritizing a lightweight experience, the ASICS Novablast 5 offers a more agile alternative at a lower price point.

Additionally, we think the ASICS Superblast 2, despite its similar price, provides enhanced responsiveness and reduced weight, making it a superior choice for runners seeking a more dynamic ride.

ASICS Gel Kinsei Max parts

For those emphasizing comfort without the added bulk, the ASICS Gel Nimbus 27 it's probably a more reasonable choice. Exploring options beyond ASICS, the HOKA Skyflow stands out as a fantastic alternative, combining a lighter construction with substantial cushioning.

Cushioning

Heel stack

The Kinsei Max is a maximalist shoe—there’s no doubt about it. With a towering 38.8 mm stack and the signature GEL cushioning system, it delivers more-than-enough protection for heavier runners or anyone craving deep underfoot padding.

Forefoot stack

The forefoot also meets the maximalist standard, going past the 30 mm mark with a measured stack of 30.2 mm. This makes the shoe a solid choice for long runs, even for midfoot and forefoot strikers.

Drop

The difference between the forefoot and heel reveals an actual 8.6 mm drop, just 0.6 mm off ASICS' advertised figure. That’s impressively close, confirming you’ll get the same underfoot feel the brand states in their spec sheet.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

The midsole of the Kinsei Max combines the classic GEL cushioning with a generous layer of FF Blast+ ECO, which is a moderately-soft foam also found in daily trainers like the ASICS GT 2000 13.

For a shoe in this price range, we expected something a bit more cutting-edge, but FF Blast+ ECO still delivers a reliable ride. We measured 19.1 HA on the durometer, but thanks to the GEL technology, it feels much softer than the number suggests.

Rocker

The ASICS Gel Kinsei Max features a moderate rocker design that encourages smoother heel-to-toe transitions. Thanks to its flare-shaped heel and curved forefoot, we found it delivers an interesting rolling sensation, which is especially helpful for heel strikers.

ASICS Gel Kinsei Max side

From our perspective, this rocker geometry shines on long runs, where rhythm matter more than raw speed. We tested it extensively, and with its heavy-duty build, it benefits greatly from having a curved midsole setup.

Hybrid Gel

Sporting a newer version called Hybrid Gel, ASICS refuses to let go of its long-standing proprietary tech despite its high weight and low rebound. In our runs, we discovered that it delivers cloud-plush landings as always, but definitely lacks any energetic bounce.

Toebox width - widest part

The fit of the Gel Kinsei Max caught us off guard. From its oversized look, we expected a roomy toe area, but that spacious feel never showed up during our runs.

After testing, we discovered through our gel mold that the max width reached only 93.4 mm. That’s narrower than most average daily trainers and makes this shoe better suited for those who prefer a secure, race-inspired fit or have naturally slim feet.

Toebox width - big toe

At 73.8 mm, the big toe area leans toward an average fit, but it still features an obvious taper that doesn’t follow the natural toe shape—so you’ll need to be at peace with that.

Toebox height

In terms of vertical room for the toes, the Kinsei Max truly lives up to its name.

With 30.3 mm of clearance, it’s an upper that won’t press down or cramp your toes from above.

Stability

Lateral stability test

We found solid stability in the Kinsei Max despite its towering build, though it didn’t catch us off guard. The shoe is loaded with tweaks that help keep the ride centered and steady!

Torsional rigidity

One of the key stability tricks is the sky-high torsional rigidity we discovered while trying to twist the shoe. It scored 5/5, behaving laterally like a carbon-plated racer. This setup keeps the ride centered and motion-guided, but it also takes away from natural foot movement.

Heel counter stiffness

Another trick pulled from ASICS’ stability playbook—another 5 out of 5. Runners who dislike stiff heel counters won’t enjoy the Kinsei Max either, as it feels like a block of stone locking the heel!

Midsole width - forefoot

This shoe also felt impressively stable thanks to its extra-wide midsole, offering a jumbo-sized landing platform for both midfoot and forefoot strikers. We measured 120.0 mm, but it felt even broader during our runs.

Flexibility / Stiffness

While the Kinsei Max is incredibly rigid when twisted, we were relieved to find it’s much more forgiving in longitudinal flex. Scoring 28.7N, it works surprisingly well for daily runs and even some casual walking.

Weight

One of the things we dislike most during lab testing is when a shoe looks feather-light but turns out to be a brick. That’s definitely not the case with the Kinsei Max: it looks heavy and delivers on that impression.

In fact, at 11.35 oz or 322g, it's one of the heaviest shoes we've tested. We found its tank-like build hard to overlook, and we’re not going to sugarcoat it. If you're into comfort and don’t care about weight, it might be fine—but otherwise, this weighty monster won’t work for you.

Breathability

Achieving a balance between breathability, comfort, and durability is often challenging, and ASICS aimed for a middle ground with the Kinsei Max.

We settled on a 3/5 score after analyzing this shoe with our smoke machine. That's not a bad outcome, though at the price of this shoe, some may have expected better airflow for summer runs.

When we moved the upper over the light, it became clear to us that ASICS engineered this shoe as the opposite of most models—ventilation is prominently on the tongue but scarce on the toebox. Curious.

ASICS Gel Kinsei Max microscope

We confirmed the lack of airflow in the toebox with our microscope. While there are some openings, those are blocked because the secondary layer is not perforated.

In fact, while most maximalist shoes usually have plush tongues, the Kinsei Max has a thin one. What a weird shoe!

Outsole hardness

Flipping the shoe to check the outsole, we recorded an average 82.2 HC reading—nothing unusual there. However, just like the rest of the Kinsei Max, this outsole takes a different path with an offbeat design.

ASICS Gel Kinsei Max pads
There’s a massive central void that might easily trap stones.

ASICS went with thick layer of FF Blast rubber to create extra-smooth landings and topped it off with only three small pieces of AHAR+ rubber in high-impact zones of the heel.

Based on our testing and past experience with similar hybrid-rubber setups—like on the Cumulus 26—heel strikers should see standard wear, but others may see faster-than-average outsole erosion.

Misc

Price

The Kinsei Max comes with a steep price tag that’s tough to justify. While the build quality and materials are great, they’re not groundbreaking compared to similarly priced options.

If you love GEL cushioning and aren’t bothered by the extra weight, it might still be a solid pick. Otherwise, we think most runners would be better off exploring alternatives or waiting for a price drop.

Reflective elements

We were glad to find reflective details on the heel of the Kinsei Max—something we believe every running shoe should include for added safety during low-light runs.

Tongue padding

Despite the shoe’s substantial weight, the tongue is surprisingly thin.

We measured just 2.6 mm of padding between the laces and the instep, which might feel lacking for runners seeking a plush, cushioned step-in experience.
