Intro
This is twin brother to the Skorpius CR II, with which it shares the shape, closure systems, ski/walk mech, and last and sole. Like the Skorpius, it’s engineered from Pebax Rnew, but with no carbon filaments in the plastic. The result is a boot that maintains the same focus on practicality and comfort, combined to provide even more accommodating skiing performance, making them ideal for all-round use.

Walking
The Skorpius’s spec sheet is spot on: there’s ample room in the forefoot before any bootfitting work, which favors a natural walking action, aided also by good, friction-free cuff range of motion. The liner is quite sturdy, provides good balance to the ample cuff mobility and delivers good support, even on missions carrying heavy packs. The swing-lock ski/walk system is less bulky than many traditional ones—it just takes a few goes to get accustomed to the action.

Lab
Put them on, close them up, and go ski—just like an alpine boot. They’re easier to put on than the average boot in this class, and just as easy to get out of, and once on, the feeling of comfort is immense. An amenable boot, even for those new to touring. Plus, it has many features that make operation a breeze, from the removable PU insole, to improved thermal insulation when needed, to the wide Velcro power band combined with the upper buckle with numerical scale for precise micro adjustment.

Skiing
The few (though substantial) differences when compared to Skorpius CR II yield a boot that will suit more general use by intermediate-level tourers. The carbon-free plastics are more forgiving and have an elastic response that’s easier to exploit by those with a less powerful, more tentative skiing style. Plus, the room around the front, which makes for easy walking, makes for a more instinctive steering feel, a factor that could appeal to intermediate tourers, whereas the more advanced might prefer something that fits a little snugger. The flex is plush and progressive, but does tend to collapse with aggressive inputs or heavier weights, making it ideal paired with light, not overly fat skis, the kind that sit centrally in this class. Supportive if you find yourself in the backseat, and sensitive edge control.

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.
