Hoka Tecton X 4 Review: The Carbon Plated Racer for Any Trail

Design & Features

Hoka made the Tecton X 4 using its ProFly X series of technologies. The idea was to make a shoe that feels legitimately speedy, even on super gnarly terrain. This, after all, is a shoe that Hoka athletes wear in their biggest, most competitive races around the world.

A significant element of the construction is parallel carbon plates to increase pop in the gait cycle, and there's also a new Matryx Micro textile upper that enhances breathability during all-out efforts. The shoe is built with two layers of PEBA midsole foam underneath, and finished with an extended knit collar and updated lace structure for better lockdown and support than the previous iteration had.

While I was visiting the Hoka FlyLab in Chamonix, Jared Smith, the brand's senior product line manager, explained that the Matryx Micro textile upper is something that Hoka has continued to use through each iteration of the Tecton. “It’s a balance of durability and water mitigation. It's hydrophobic, meaning it doesn't allow water to be absorbed into the material, which prevents blistering, stretching of material, and it's also incredibly durable, lightweight, and breathable.”

For cushioning, the Tecton X 4 utilizes two different densities of PEBA compound to make the shoe responsive and lightweight. “On that top layer, we're using a softer compound that's right underneath the foot,” Smith said. “Then just underneath that top layer, we have the dual parallel carbon fiber plates that run the length of the shoe from heel to toe.” The decision to use dual plates instead of a single plate addresses technical terrain, like what a runner encounters on, say, a 100-plus-mile loop around Mont Blanc. “Running a full carbon fiber plate can challenge what that stability looks like. So using the parallel plates allows us for a little bit more suspension.”

Hoka Tecton X 4 Testing Impressions

Feel on the Trail: Poppy, Grippy & Well-Cushioned

I’ve run in tons of carbon-plated road shoes, but never a carbon-plated trail shoe. While there is a specific and undeniable boost—the shoe has much more pop than something like Mount to Coast’s T1—the Tecton X 4 doesn’t have that “holy moly this changes everything” underfoot feel that characterizes road supershoes. Maybe one of these days I'll take them to the track just to see what kind of splits they could throw down.

Flat out, the shoe does not slip or budge on the trails. In all my runs, never once did I experience that little skid-scare where you think you’re going to butt-plant a steep section. Going up and down was like having little lightweight Jeeps on my feet—this shoe was made for this. That’s thanks to the Vibram Megagrip, a high-performance, sticky rubber outsole compound engineered to deliver traction on both wet and dry surfaces.

With its double-layer midsole, this shoe also notably cuts down on the trauma the body experiences during big efforts. After a full morning of launching off rocks on the steep descents around Chamonix, my (distinctly non-elite) body didn’t feel like I had done the numbers that I had. A 10-mile day with 5,000 feet of climbing would typically leave me really feeling it in my ankles and knees. Having run in the Tecton X 4, I felt just a normal amount of tired (that is, tired, but not wrecked).

On the Update: Versatile & More Stable

At a group run in Chamonix, Hayden Hawks, who has been a Hoka athlete for 10 years, said he has appreciated the versatility of all versions of the Tecton. “I actually won the CCC 100K in 2024 in the Tecton X 2.5. I was able to podium at Western States in that shoe, and then I also won Black Canyon 100K in that shoe," he told me. "And the reason I bring up those three is that they’re completely different races. Everything from more runnable desert-type terrain, like Black Canyon 100K to the mountains in Chamonix.” Hawks was on the team of elite athletes that tested early prototypes for the fourth iteration of the shoe and gave feedback for the final product. None of my test runs reached the 100-kilometer mark, but they did include the full span of surface variety, and the shoe felt good on all of them.

Hawks also admitted that while the Tecton X 3 was a solid shoe, there were noticeable differences between the 2.5 and the 3 that informed the design of the new model. “I really love that the Tecton X 4 feels more stable. It feels like you sit in the foam rather than on top of the foam. I felt like in the 2.5, I sat in the foam. In the 3, I felt like I sat on top of the foam. But the 4, it feels like you are back in the foam, like it was in the 2.5.”

I never ran in previous models, but I agree that the foot seems to fit inside the foam rather than on top of it. Those who were disappointed with the 3 might find themselves renewing their Tecton X loyalty with the 4.

As for Hawks, he was supposed to run CCC this year, a 100K with 20,000 feet of elevation gain, but injury kept him sidelined. If he had been able to start, he said he definitely would have run in the Tecton X 4.

Sizing: Not a Perfect Fit

My only major complaint with the Tecton X 4 is sizing. It is absolutely necessary to size up. In my opinion, every single person buying this shoe should size up a half size, and some will need a full size. Buyer beware when purchasing online. (Go buy it at your local specialty run store!)

For context, I usually wear a women’s 11, and often shift to a men’s 9.5. When I put on the men’s 9.5 Tecton X 4, it was a total no-go. A men’s 10 was better, and a men’s 10.5 was perfect. That’s a pretty significant difference. I’m not sure if they’re doing that so they can claim a men’s size 10 weighs 9.7 ounces, or if the shoes really just turned out small, but the sizing is way off.

About That Gaiter…

The other component that takes some getting used to if you’ve never worn gaiters is the knit collar. Once you’ve worn them a few times, you don’t even notice the feature, and it certainly does its job of keeping rocks and debris out of the shoe. But putting it on the first few times is a little awkward—you have to put your foot into the collar first, then secure it in the shoe. You'll want to wear a taller sock to avoid rubbing; for this one, super-low and millennial no-show socks are a no-go.

Our Final Verdict

When I was in Chamonix, I sat down with Bekah Broe, senior director of product performance at Hoka, to talk about the evolution of the Tecton X 4. Broe is convinced that trail running is getting to the same place that road running has been for a while now, where shoes are changing the game entirely. “We’re seeing Western States and UTMB come down to a matter of minutes, if not seconds. We’re seeing athletes being able to sprint at the end of running 16, 17, 18 or more hours.” Case in point: Ben Dhiman and Blandine L'Hirondel both set new course records at the 2026 UTMB. Dhiman was the first man to run it under 19 hours, and L'Hirondel became the first woman to go under 22-hours.

But the benefits of high-powered shoes like the Tecton X 4 aren't just for the elites. Once you’ve got the shoe on—which might take an extra minute or two—and in the correct size, this is a dream for long days on technical trails, whether you're running through the mossy forests of the Pacific Northwest or the rocky peaks of the French Alps. It might be overkill for casual trail running, though; I’ll be reaching for this shoe for anything technical over two hours—like a full day on the Wonderland Trail in Mount Rainier National Park—and especially for longer trail races when I really want that dual carbon-plated pop.
