Arc’Teryx’s new lightweight mountaineering shoe won’t weigh you down as you climb those alpine peaks


Arc’Teryx has launched a lightweight three-season GORE-TEX mountaineering shoe. New to the SS21 range, the Acrux LT GTX boot is designed for precision and efficiency.

It is part of the same range as the technical trekking shoe, the Arcteryx Acrux TR GTX – number 3 in our ranking of the best hiking boots – and the Acrux AR mountaineering shoe, which is intended for the exploration of the mountain. mountain all year round. The Acrux LT GTX sits somewhere in between: it’s more specialized for tough alpine hikes and climbs than the TR, but lighter and with less insulation than the AR, making it more comfortable for spring and summer trips.

At the heart of the design is a carbon midsole with PU foam core, slim 3mm thick and super light, and adds stiffness from heel to toe. The idea is that it allows climbers to move confidently over difficult terrain. This boot weighs 650g, which matches other good, lightweight mountain boots on the market.

There’s a Vibram MONT outsole, which is a version of the same grippy material that provides traction on the best hiking boots, but specialized for more extreme use. It is designed to maintain its grip at low temperatures, and is firmer, to make it more suitable for use with crampons (these are compatible with semi-automatic crampons). This is paired with the same brand’s ‘Litebase’ technology, which essentially means it’s significantly lighter and thinner than traditional Vibram Megagrip soles.

A rubber toe cap has been 3D molded, and there’s a toe profile designed for precision on the trails. And of course there is GORE-TEX for reliable waterproofing.

The Arc’Teryx Acrux LT GTX boot is available for purchase now, with a suggested retail price of £ 300 GBP / $ 400 USD.
