In words

Intro
Scarpa's semi-carbon boot designed especially for women. Unchanged for the past few years, it continues to set the standard for women racers the world over who are looking for a boot that is slightly more easygoing than a pure race model, but just as powerful. The cuff is in carbon fiber, the shell in Carbon Grilamid LFT. It has no real competition from other models with W in the name.

Walking
More easygoing compared to its race siblings thanks to a roomier toebox and more generous volume, it strikes the right balance between responsiveness and comfort, letting your foot breathe so you can wear it for long periods without too many problems. The 75° cuff rotation offers complete freedom of movement, be it when hiking on technical terrain or skinning uphill. Light on the foot, it delivers verticals and performance. An excellent training option.

Lab
It's halfway between the Alien and Alien 4.0. The liner is thinner and less stiff than the pure race models, has a long padded tongue, and covers the ankle bones and Achilles heel while leaving lots of freedom of movement. There are further gains to be made from bootfitting and the ski/walk mechanism is simple but effective, both in ascent and in descent.

Skiing
As powerful as only a race boot can be in descent; it's less twitchy than a full carbon, and you don't need to drive it hard for it to bend. The right amount of progressive flex, it accompanies you when turning or sideslipping without shaking the fillings from your teeth. The high tongue protects the shinbone from pressure when the cuff is closed, and you can ski for a long time without any real problem. A real warhorse if you want to push vertical limits, be it in ascent or descent.

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.
