Intro
It may have the same ski/walk mechanism and BOA dial, but the similarities with the Alien 4.0 end here. Scarpa's semi-carbon model is altogether different in terms of responsiveness and overall concept. It's presented as the missing link between the race and fast & light segments, thanks to a sturdier liner with a stiff tongue. Though less extreme, more forgiving and comfortable, it remains a solid choice at a competitive level—just below the top of the results table.
Walking
Similar to the Alien 4.0 in terms of walkability, though it doesn't reach the same heights in terms of smoothness and performance of the top-of-the-line boot as the sole is less rounded. On the plus side it has more internal volume, which is well distributed to let the foot drive and breathe at the same time. The cuff rotation approaches that of a full-carbon model, with a nice balance of fore and aft movement. Its raison d'être is Grande Course races, fast & light escapades and sprints the finish line—unless you're up there with the likes of Robert Antonioli.
Lab
As with the Alien 4.0, you just need to tip the cuff back; entry is pretty easy with the liner in the shell. In terms of fit, it's more accommodating than its sibling, though still technical. The liner is low like a bikini liner at the back and higher at the front, with a nice firm padded tongue that is longer than the cuff, definitely one of its strong points. The ski/walk mechanism keeps it nice and stiff in ski mode, and free and easy in walk mode, and is easy to handle and engage.
Skiing
A semi-carbon behaves differently to a full-carbon boot on the downhill, and the Alien 1.0 is probably the most balanced for a number of reasons. The stiff, padded tongue is supportive and stops the plastic from pinching. Then there's the effective forward lean that works together with the low, forward pivot point on the shell. Not as stiff as a full-carbon, it's softer, yet progressive, flexing at the right moment. You need to know how to manage it in terms of fatigue and skiability. And if you get it right, you'll benefit enormously, both on and off the race track. There's a reason that it's the top choice for elite skiers during training or on their own time.

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.
