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.
