Kailas FUGA EX 330 review

Based on our lab tests and running experience, we believe the Kailas FUGA EX 330 is a great trail shoe for:

• Runners who love bold designs and want to try a lesser-known brand.
• Ultrarunners looking for a rugged, heavily-cushioned trail shoe built for long distances.
• Runners seeking a versatile shoe that handles different trail conditions thanks to its variable-depth lugs.

The biggest drawback of the FUGA EX 330 is its steep price tag. Spending $200 on a trail shoe is a tough sell for most runners, and we believe those on a tighter budget should consider alternatives like the ASICS Trabuco 14 or HOKA Speedgoat 7 instead.

We also found the FUGA EX 330 heavier than expected. Therefore, runners looking for a lighter, more agile feel underfoot should check out the adidas Terrex Agravic Speed.

The FUGA EX 330 makes a convincing case for long mountain outings in this test. We measured 136 SA at the heel and 129 SA at the forefoot, with both results comfortably above average.

In our view, the front deserves particular praise for the impact protection it provides, making it a very interesting option for ultra-distance races.

Kailas uses a supercritical foam midsole, and we found a good amount of rebound at both ends. Energy return reached 65.5% in the forefoot and 62.1% in the heel.

We like that the midsole combines solid impact protection with a welcome dose of bounce, making cushioning one of the shoe's strongest features. However, given its premium price, we believe this is the bare minimum we all should expect.

With 39.9 mm, there's a substantial amount of material beneath the rearfoot, putting the EX 330 firmly among the taller trail shoes we've tested in the lab.

For runners who prefer plenty of separation from the terrain, this generous stack is an amazing feature. The trade-off is reduced ground feedback, as usual.

The forefoot doesn't skimp on material either, and we would say that it's even more impressive than the heel. At 34.2 mm, we found a generous platform beneath the ball of the foot.

We measured a 5.7 mm drop, close to the 5 mm that Kailas advertises.

That's a moderate difference in height between the two ends, preserving the relatively low-drop geometry of the model.

The thick midsole has a more resistant feel under pressure than its plush-looking profile implies. We measured 42.8 AC with our Asker C durometer, placing the foam on the firmer side of average although by a slim margin.

Cold resistance brought a positive result. After 20 minutes in the freezer, the foam became just 15% firmer.

The FUGA EX 330 features a pronounced upward curve at the forefoot and a beveled heel. Given its towering forefoot stack and long-distance focus, we weren't surprised to find a rockered midsole designed to promote efficient transitions over extended runs.

The substantial exterior hides a fairly snug interior. After making a gel replica, we measured 92.8 mm across the widest part of the forefoot, a narrower-than-average result.

For an ultra-focused shoe, this is an important limitation. Runners whose feet need extra space as the hours pass should pay close attention to the fit.

Space narrows further near the big toe, where we measured 70.9 mm. The tapered front restricts the room available for the toes to spread, making this a poor match for runners who prefer (or need) a broad toebox.

Vertical room is less restrictive.

We measured a toebox height of 27.5 mm, putting this dimension close to average.

The Vibram Megagrip outsole delivered a very strong result, reaching a coefficient of friction of 0.80 in our traction test over wet concrete. There's plenty of reassurance in that score for runners who place secure footing high on their list.

We measured a lug depth of 3.4 mm, although it's worth noting that KAILAS uses a variable-depth design, with deeper lugs along the sides reaching up to 6 mm.

We found this approach particularly interesting, as most brands stick to a more uniform lug depth. Instead, KAILAS aims to make the FUGA EX 330 more versatile across different terrains without compromising its ability to run fast.

We found triangular lugs arranged in several directions, with small dots along their edges as part of Vibram's Traction Lug design.

The rear uses larger blocks around a central, arrow-shaped opening of exposed foam, with additional grooves in the heel lugs for braking purposes. We like the combination of different tread zones, while the choice of Vibram Megagrip Litebase over regular Megagrip helps keep the weight as low as possible.

We noticed more resistance through the forefoot than usual during our runs, and our 30-degree bend test confirmed this with a reading of 20.3N. Despite having no plate, we found the FUGA EX 330 surprisingly stiff... almost like a plated shoe!

At 10.6 oz (301g), we wouldn't call weight a strength of the FUGA EX 330.

There's a lot of cushioning and upper reinforcement, but the final reading still makes this a substantial shoe to carry over long distances. Runners looking to minimize weight have lighter options to consider, that's for sure.

We wouldn't recommend the FUGA EX 330 for runners with stability issues.

Its aggressive, forward-rolling design is better suited for neutral runners who want to maintain momentum, but the combination of a narrow midfoot and towering stack height makes it a poor choice for overpronators.

We needed 16.1 Nm of torque in our torsional test, placing resistance to twisting close to average.

The heel counter earned 3/5 when we squeezed and bent it by hand. We found moderate resistance, giving the rearfoot some structure while retaining a degree of flexibility, feeling very similar to a road daily trainer.

Across the widest part of the forefoot platform, we measured 117.2 mm.

That gives the shoe a reasonably broad base beneath the front for those that strike with this part of the shoe, with some extra material around the landing area.

The midfoot features an aggressive, highly-tapered design that almost resembles a super shoe. In contrast, the rearfoot is surprisingly generous, with a heel platform measuring 97.0 mm across.

In our view, this is one of the EX 330's most useful stability features. The wider heel provides real extra support during heel landings.

The protective overlay reaches high around the toe, adding coverage in an exposed area. But even so, we would have liked a stronger performance from the TPU reinforcements, as we awarded it a 3/5.

Inside the heel, we found another 3/5 result in our Dremel test. The lining offered reasonable resistance to abrasion, but it didn't emerge as a particularly tough part compared to other trail shoes.

The outsole impressed us more with its grip than its durability. After putting the Vibram rubber through our Dremel test, we measured a 1.5 mm dent, which is deeper than we usually expect from this compound.

We measured just 1.3 mm of outsole rubber beneath the lugs. The Megagrip Litebase construction uses a thinner backing than regular Megagrip, reducing the amount of rubber between the tread and midsole.

We would have preferred more material here in a shoe designed for long distances, especially given the disappointing wear resistance we found in our abrasion test. However, considering the EX 330's already high weight, we suspect that choosing Litebase was more of a necessity than a preference.

Good news for warm-weather ultra races: we rated the EX 330 4/5 after pumping smoke through its upper. The XDiMESH construction allowed good airflow, earning a positive result despite the extensive reinforcement around the toe and sides.

Under our microscope, we found clear openings between the reinforced strands. Those gaps help explain the ventilation, making breathability one of the upper's more appealing features.

Kailas uses thin round cords through fabric loops, plus a metal hook at the upper closure. We discovered before our first run that the AWS 3.0 system lets runners adjust two zones independently, adding useful control over tension. A flap on the tongue covers a pocket for storing the excess cord, although the process is not as fast as we hoped.

Beneath the AWS 3.0 system, we measured 7.8 mm of tongue padding. That's a generous layer between the cords and the instep.

We found a fully gusseted tongue attached along both sides, giving it more anchoring than a tongue left free at the edges. This helps limit sideways movement and keeps small debris away from the instep.

The insole measured 5.2 mm, which is a bit more than usual.

We removed the perforated insole without difficulty, so swapping it for a replacement is pretty fast.

There's no heel tab on the EX 330, although we noticed a tiny gaiter attachment.

We found no reflective elements when checking the shoe in our dark room.

The EX 330 comes with a sky-high price tag, there's no denying that. Despite packing some serious technology, we believe many runners will struggle to justify the cost.

However, for those who find it a perfect match, the investment might be worth it.
