HOKA Tecton X 4 Review 2026: Trail Super Shoe Tested

The HOKA Tecton X 4 launched globally on 20 August 2026, and UK stock landed the same week — so instead of the usual pre-launch guesswork, we can now confirm the full spec sheet, UK pricing and what’s actually changed. For triathletes tackling off-road runs (XTERRA-style events, technical run legs, or long trail training days), the Tecton X line has always been HOKA’s carbon-plated option built for grip and protection on rough terrain rather than pure road speed, and the fourth generation keeps that formula while tightening up the fit and trimming a little weight.

Key Features

• Dual parallel carbon-plate system, now fully hidden inside the midsole — HOKA has ditched the exposed carbon “winglets” at the sidewalls that defined the Tecton X 3’s look.
• Two-layer PEBA supercritical foam midsole (PROFLY X), with the plate structure adjusted to add more “pop” through the gait cycle versus the X3.
• New Matryx® Micro woven upper, more breathable and less water-absorbent than the X3’s upper, with an extended knit collar and reworked lacing for lockdown.
• Vibram® Megagrip Litebase outsole with 4mm lugs, trimming outsole weight — HOKA says the X4 is about half an ounce lighter than the X3 despite matching stack height.
• Confirmed weight and stack: men’s 275g (US M10) at 40mm heel / 35mm forefoot; women’s 234g (US W8) at 39mm/34mm. Both carry a 5mm drop.

Our Verdict

The Tecton X 4 is aimed squarely at triathletes and trail runners racing technical, mixed-terrain courses who want a carbon-plated push without giving up HOKA’s trademark underfoot stability — think XTERRA-style off-road legs, mountain ultras, or any race where you need propulsion on singletrack rather than tarmac. It’s a race-day shoe, not one to log big weekly mileage in.

Compared with the Tecton X 3, the headline change isn’t the plate count or the foam — both carry the same dual-PEBA, dual-carbon-plate concept forward — it’s how that plate is packaged (hidden rather than visible at the sidewall) and a fully reworked Matryx Micro upper. Weight is essentially a wash at 275g for a men’s size 10, in the same range as the X3 rather than a dramatic drop, but the shoe carries that weight with a noticeably more locked-down, breathable upper.

At £220, it sits at the top of the trail super-shoe market alongside the likes of Salomon’s S/Lab Phantasm and Nike’s Ultrafly. For a deeper dive with mileage-tested comparisons against the X3 and rival trail racers, see Road Trail Run’s multi-tester review and Believe in the Run’s review.

Buying Tips

• Try before you commit if you can — the reworked Matryx Micro upper and lacing run more structured through the midfoot than the X3, so if you’re between sizes on the outgoing model it’s worth checking fit in-store or via a retailer with a returns policy.
• UK stock is currently with independent trail-running retailers (Run North West, Achilles Heel) rather than HOKA’s own UK site, which still lists the model as coming soon — worth checking both for your size and colourway.
• This is a race-day carbon shoe with a low-durability PEBA midsole, not a daily trainer — save it for key off-road races and hard efforts, and keep a durable trail trainer in rotation for everyday mileage.
