In words

Intro
Unchanged from last season, it’s now in its sixth edition, with each iteration receiving minor refinements aimed at improving the overall performance. A few grams have been added with the latest upgrade, but only where needed, while it still remains one of the reference boots when it comes to absolute minimalism (see the hollow heel). The enhancements include the addition of a soft foam layer on the sole on the outside of the forefoot to enhance foot roll, and a higher gaiter.

Walking
The layer of soft foam on the outside of the forefoot around the sole adds a little extra power to your stride, attenuating slightly that jerking motion underfoot that puts it halfway between the Gignoux and the natural gait of the Alien 4.0. There's nothing to say about the cuff rotation, it is as free in its movement as it is from friction. Il tallone non è bloccato in sede come su Alien 4.0 e tende un po’ a scalzare in camminata (ma anche a essere conciliante con piedi meno magri posteriormente).

Lab
The fit is full carbon, but compared to its direct competitors, there’s a tad more space, with some wiggle room for the toes. The cuff foam is thick and one of the best out there, providing a good balance between stability and damping. It takes a bit of time to figure out the best tension for the ski-walk mech and closure system. The well-designed buckle makes sure the cord stays put during races. A modicum of care is needed when donning crampons, as the heel is super minimalist.

Skiing
Several factors contribute to making it the reference boot in terms of skiing performance, starting with the thick foam in the cuff, which improves progressive flex and damping. But it’s really the overall package that contributes to the result: a high and extended flap that closes well allowing for better turn control and fast driving during descents; the perfectly calibrated forward lean; the pivot point placed high and rearward on the shell to deliver the most effective geometry; the overall rigidity of the structure. Skier inputs are directly and precisely transmitted, allowing for corrections to be transferred to the ski-binding system instantly. On the downhill, it’s the best out there.

Intro
Safety, a culture of doubt

Beyond the basic definition, there’s nothing as variable as snow conditions and the human psyche when under emotional stress. That's why, after purchasing the right self-rescue kit and airbag backpack, it’s paramount you do your research, train, scrutinize your decisions and, if necessary, opt for plan B. And, at least for now, don’t rely on artificial intelligence.

Intro
Products for mountaineers

Once you’ve chosen your skis, boots and bindings, your thoughts then turn to harnesses, crampons, ice axe and helmet, though perhaps not everyone, and not straight away. While it’s true that when starting out, especially for those transitioning from resort skiing who just want to start surfing some pow, the important thing is to get self-rescue equipment. It’s equally true, however, that the sport we love is a combination of two words: skiing and mountaineering.

Split All Mountain
Intro
Boards, boots, and bindings for splitboarding

Materials are evolving, which is increasing the opportunities for pushing the boundaries of mountaineering splitboarding. It’s no longer just about easy tours, a few jumps and a beer. Thanks to innovative new setups and growing knowledge within the community, long ascents and steep terrain no longer intimidate.

2025
Intro
Skimo bindings

They’re probably the element of your setup that’s evolved the most and seen the most crossover between disciplines. Which is why in general lighter bindings have adapted to make allowances for the trend for opting for wider skis, with hybrid drilling patterns and a greater selection of ski brakes. But the aspect that requires most scrutiny is the height difference between the front and rear pins.
