Arc’teryx Acrux LT GTX hiking boot: Design and features
This is a sleek and stylish boot that features some innovative technologies. The design is focused on providing maximum technical performance at minimal weight. And the Acrux LT is remarkably lightweight for a B2 mountain boot, tipping the scales at just 650g (23oz) per boot in a men’s size UK 9/US 10. Few boots offer such technical capability at such low weight, with the possible exception of the new Mammut Taiss Light Mid GTX and perhaps the Scarpa Ribelle Lite.
The midsole is comprised of a 3mm carbon fibre shank embedded in PU foam rubber. This ensures plenty of stiffness and stability underfoot with minimal weight, while the addition of PU offers durable cushioning. A plastic welt insert at the heel enables the boot to be used with C2 semi-automatic crampons.
The uppers are made from an ultralight woven polyester fabric called ‘SuperFabric’, designed to be flexible but exceptionally abrasion resistant. Low profile ‘to-toe’ climbing-style lacing ensures a close, precise fit, with quality metal hardware used for the upper triple sets of lace hooks.
High-wear areas like the heel and toecap are also overlaid with a TPU film. This offers further resistance to abrasion and impacts but saves considerable weight compared to a traditional rubber rand.
The boot is not insulated but is lined with a waterproof-breathable Gore-Tex performance comfort membrane. The tongue is also gusseted to prevent moisture ingress and help stop grit and other debris from finding its way inside.

Arc’teryx Acrux LT GTX hiking boot: Performance and comfort
This boot’s stiffness makes it a very competent and capable performer on steep ground, enabling you to edge with confidence. The highly tapered toe is also an ideal shape for jamming into small rock pockets. That front climbing zone under the toe also works well on a variety of different types of rock. You get plenty of feel too, which makes for good precision – it’s easy to tell where you’re putting your feet. As such, it’s a great boot for technical climbing and scrambling.
It works just as well with a crampon fitted for snow and ice too, which again is largely down to the boot’s stiffened midsole. The pronounced heel welt works well with common C2 clip crampons like the Grivel G12 and the Black Diamond Serac, and we got a secure fit with no issues. For prolonged cold-weather use, we’d recommend wearing heavyweight mountaineering socks (and it’s worth sizing your boots accordingly, to allow for this). That’s because the fabric uppers aren’t the warmest, and though the Gore-Tex lining provides a little insulation, you still need to guard against numb toes.
Similarly, if you’re used to B2 boots with stiff and supportive leather uppers, you might also find the fabric construction lacks a little support and protection. On test in Snowdonia, the SuperFabric weave seemed to hold up well even when subjected to sharp slate and scree, but these still aren’t the sort of boots you can go kicking rocks in.
The boot is very close-fitting, which is partly what makes the Acrux LT feel so agile and precise. But it’s worth noting that the slim, low volume last probably won’t suit those with wider feet, especially if you prefer a roomy toe box.

Arc’teryx Acrux LT GTX hiking boot: overall verdict
Despite a couple of drawbacks, the Arc’teryx Acrux LT is still an impressive package, with a precise feel that delivers superb climbing performance, with or without a crampon fitted. It’s remarkable that such a lightweight boot is also so technically capable. The flipside? Cushioning is fairly spartan and the fit is narrow, both of which make it relatively unforgiving on long walk-ins. As such, we reckon this is a boot best suited to ‘done in a day’ Alpine-style mountain missions.
