Hoka Tecton X 4 First Run Review: A Familiar, Energetic Trail Racer
Hoka's flagship carbon trail racing shoe returns with a more breathable upper and a lively Profly midsole. Our first impressions after seven miles of mixed coastal trail.
Introduction
The Tecton X 4 is Hoka’s pinnacle trail racing shoe, built for the longest distances and technical terrain, the kind of shoe aimed at races like UTMB. It sits at the top of the brand’s trail lineup above the Rocket X trail racer, which is geared more towards lighter trails and gravel. Within the range, the Tecton X 4 is the flagship carbon racer.
This fourth version stays fairly similar all around to the Tecton X 3, with changes that tweak the fit and the shaping of the carbon parallel plates, plus a new, more breathable matrix micro upper. Pricing sits at £220 or $275, and the shoe weighs 269 g or 9.5 oz in a UK size 9 (US 9.5). The men’s spec is a 5 mm drop with 40 mm of stack at the heel and 35 mm at the forefoot.
Fit and Sizing: Consider Going Half a Size Up
Fit is the area where the first run raised the most practical questions. In a normal Hoka road shoe size, the fit was okay, but with a reinforced upper and ultramarathon distances in mind, there is a strong case for going half a size up. Our tester ran in a UK 9, half a size up from normal, and considered that the smarter choice, giving enough clearance towards the end of the toe box.
Even with that extra room, the toe sits quite close to the top of the big toe. The matrix upper with its stretchy vamp does spread and give a decent amount of flex and toe room, which is nice for an ultra-friendly fit across the toe knuckles. Still, more clearance would be welcome over the long haul to avoid black toenails. There was some forward slipping on the first run that will need firmer lacing on subsequent runs.

Upper and Gaiter: Familiar and Functional
The new matrix micro upper uses very lightweight materials with reinforced sections around the toe box and sides for extra protection and structure on the trails. The built-in gaiter carried over from the Tecton X 3 rises over the ankle and stops debris getting inside the shoe. Even if you don’t run in conditions where a gaiter matters, it doesn’t detract from fit or comfort; it just makes the shoe slightly harder to pull on.

The heel collar is quite thin, with not much by way of heel counter, so there can be a bit of movement and a slight tendency for the collar to dig in. Over very long runs that could become a problem. Around the heel and midfoot, hold was decent, and the gaiter adds some structure to the upper. The upper is not the most forgiving or cushioned compared to a road shoe, but it was perfectly comfortable over a first run of just over 10 miles.
Midsole and Carbon Plates: Bouncy but Balanced
Underfoot, the Tecton X 4 uses a dual density Profly midsole, a PEBAX-based foam with a slightly softer layer on top and a firmer layer beneath. Two parallel carbon plates run the length of the shoe, and because they are not a full stiff plate, the shoe keeps flexibility both fore-aft and side to side. That matters on uneven ground and sharp rocks, where a little flex is valuable while still adding the propulsive and stabilizing benefits of carbon.
The ride is energetic and immediate in its return, with genuine bounce, especially noticeable when landing further back on the heels. On runnable stretches it runs like a dream, giving back a lot of energy and protecting from what is coming up underfoot. Compared to the Nike Ultra Fly Trail ACG, which feels softer and more absorbent, the Tecton X 4 leans more immediate and springy. There is still a bit of ground feel in the forefoot, which keeps you feeling in control.
At faster paces the response from the midsole grows noticeably, and it starts to feel like a shoe you could race a trail marathon in. At easy paces it feels nicely cushioned, and you don’t feel the plate pushing you forward aggressively. It is firmer and more stable than a road-focused carbon shoe like Hoka’s Cielo X1 3.0, which is much more aggressively rockered and softer.
Grip: Vibram Megagrip with Traction Lugs
The outsole is Vibram Megagrip with Hoka’s traction lugs, small protruding elements that add bite. The 4 mm lugs are relatively flat, giving extra grip and a smoother ride on harder trails, with enough bite for soft terrain as long as you are not venturing into very deep mud.
On the first run’s dry, dusty and sandy sections with loose stones, grip was fine with no slipping, and the shoe coped well with everything underfoot. Grip on wet and soft ground remains to be tested properly.

Ride and Handling on Mixed Terrain
The first run covered seven miles of the North Devon Coast Path through a textbook mixed bag of terrain: hard-packed runnable trail, grassy sweep downhills, narrow rutted sections, steep steps and steep narrow descents littered with loose stones and debris.
On the runnable stuff, the shoe gave back loads of energy and felt really lively. In the narrower, more rutted bits where careful foot placement is needed, the midsole liveliness sometimes made things feel a little wilder than ideal, and the bounce could fire you off in different directions on steep downs. If you are not especially confident on technical trails, that is worth keeping in mind.
When the foot turns on uneven terrain, the outer heel collar rises up into the ankle slightly. It was not bad on the first run, but over a long day it might accentuate. Otherwise the platform felt nicely secure, and this is not a wildly unstable shoe. Compared to something like the Adidas Terrex Agravic Speed Ultra or Speed Ultra 2, which have narrower designs, the Tecton X 4 feels like it gives you a bit more stability plus punch from the midsole setup.
First Verdict After Seven Miles
The first impression is a familiar Tecton X ride: punchy, lively and energetic, best when you can attack runnable ground and get lots back from the midsole. If you liked the Tecton X 3, this is a fairly familiar setup. It feels like a modern trail shoe built for efficiency and moving fast over mixed terrain, with the main benefits coming from comfort and added bounce over long distances and the ability to handle a wider range of terrain than some rival trail super shoes, which lean more towards the light trail and gravel end.

There is still real testing to come on harder trails and in wet conditions, and a direct comparison with the Tecton X 3 is planned. But as a first impression, Hoka has again found a nice balance, adding fun and bounce without making the platform unstable.
Conclusion
The Hoka Tecton X 4 is a comfortable, well-supported and lively carbon trail racer that makes the most sense for runners tackling ultramarathon distances on runnable to moderately technical terrain. The practical advice from the first runs: consider going half a size up for the toe clearance you will want over long distances, lace down firmly to manage forward slipping, and expect a firmer, more immediate ride than softer trail super shoes rather than explosive bounce.
