A fixture at the head of any skimo race, the original Alien 1.0 established a higher performance-to-weight benchmark. It’s difficult to imagine improving on a winner like this, but no one is arguing the reformulation doesn’t do just that. We’re calling it the Alien 1.1 (SCARPA still calls it “1.0”, but hey, that’s confusing. Maybe the Alien 1.0 v2?).
Keeping the full-carbon cuff, single throw ski/walk mechanism, and BOA instep closure that gave the 1.0 its racing and adventure successes, SCARPA smartly didn’t change what wasn’t broken. Instead, they’ve taken the minor areas of weakness and turned them into strengths, which is sure to continue this boot’s legacy performance. The lower is now made of Carbon Grilamid LFT material (from the Alien RS) which brings levels of stiffness and support at a low mass. The BOA closure system remains over the instep but is now internal, providing a closer fitting and more secure closure over the foot. A pain point of the original 1.0 was the difficult-to-enter sock-style liner; SCARPA has replaced it with a Crossfit Intuition BT liner featuring a full-length tongue that provides additional support and comfort. Some folks will be most excited by the integrated gaiter which increases the weather resistance and decreases instances of soaked feet. The SCARPA Alien 1.1 is an even better ski boot than the original, at a better price to boot (yay, puns).
- Carbon Grilamid LFT shell increases stiffness and responsiveness.
- Integrated gaiter keeps your feet dry and warm, a novelty!
- Vibram UFO sole provides lasting traction on ridges and boot packs.
- Internal BOA system provides better foot hold for precise edging.
- Proven Alien ski/walk lever is still the quickest way to transition.
Update 2021/22: An updated color scheme and slightly thicker liner for comfort and performance will accompany the model.

Questions & Reviews
I wonder what is the difference between 1.1 and cheaper, standard Alien.
Weight difference is obvious, but in terms of stiffness, ski performance and durability - do they differ noticeably?
The Alien 1.1 and the standard Alien have the same lower shell in both material and shape. However, the boots do have significant differences:
- The Alien has a full liner, while the Alien 1.1 has a bikini liner with a full tongue which increases the rearward ease-of-motion. This difference in liners creates a nuanced difference in fit, and means that the standard Alien will be slightly warmer.
- The Alien 1.1 has a carbon cuff. This saves weight, and makes this boot the stiffer of the two. However, carbon makes the flex less progressive. On the other side of things, the standard Alien will be softer, but it will have a more progressive flex.
If you have any further question, I would recommend filling out a Boot Fitter!
In considering your skis at 90mm underfoot I would suggest the Alien RS as the more appropriate boot. It will also give you a little more protection from the elements on those long days playing in the mountains. I hope this helps!

I've had the Alien 1.0, but due to the carbon "triangle" ond both sides in the lower shell, I couldn't punch my area of pressure. Does anybody know whether there are similar "sheets of carbon" in the lower shell or ist the whole shell out of this matt black "carbon/grillamid mix"?
I have the same boot and had the exact same issue last week. I did the same thing, bent it back, and hopefully will suffice without breaking off. I can't think of anything else to do in the meantime to beef it up. Cross my fingers and hope it doesn't break!
The boots comes with a plastic front cuff, not the carbon front cuff that is shown in the photo. I ski this boot and love the plastic because it doesn't crack like the old ones when cinching down. Plus they ski great. Hope this helps.

If you are referring to punching out the Alien 1.1, it is not recommended by the manufacture; however it can be done. I have done it on my own boots without a problem.
although scarpa does not recommend to punch it..how did you do it? With a heat gun or with these "punching machines" where the shell can be mounted to and then e.g. a heated metal ball is pressed into the shell?
Cheers from Switzerland, stay safe!
Alien 1.1 vs 1.0: The new boot is stiffer (at least compared to my well-used originals)!! They ski better with only a marginal weight penalty (about 40 grams per boot in size 25). Compared to the original, the new 1.1 lower is quite a bit stiffer. I believe this is the primary performance upgrade, as there is essentially no lower boot flex or cuff bowing. In addition, the boa wires are internal and hold the foot much better than the original's exterior wires. Due to these modifications, the new boot is also more comfortable. With the original 1.0, I had to crank the boa as tight as possible to ski well. This resulted in pinching while skinning. The 1.1 does not require maximum boa tension to ski well, and my feet have not experienced discomfort due to over-tightening. The innovative 1.1 liner also enhances performance. Despite being a race boot, the 1.1 tongue is quite beefy and helps not only with forward comfort, but also with enhanced performance. Conversely, there is no thick liner on the back of the calf. Rearward calf pressure directly onto the stiff carbon cuff translates into shockingly instant power and control. The 1.1 front cuff also rides slightly higher on the shin which makes the new boot feel closer to a "real ski boot." Some will argue that the 1.1 does not articulate as freely as the original (due to the beefy tongue and the friction with the new boot's gaiter). A side by side comparison supports this notion, however once I started skinning I never said to myself "gosh, these are unpleasantly stiff to walk in." Additionally as the tongue and gaiter have broken in, the friction has improved. These aren't full carbon boots with a bikini liner, but they are still race boots. These will definitely perform better than the originals in races with long, challenging descents or with varied conditions. BTW, I toured and broke trail without gaiters or stir-up pants and my feet stayed dry and warm!
1.1 vs TLT7 Carbonio: The TLT's are a more substantial boot. Full coverage, full liner, heavier. While the TLT7 may be amongst the lightest touring boots, and the 1.1 is a more substantial race boot, the weight and articulation between the two are quite noticeable. The Carbonios are a stiffer, heavier boot, and while skiing rough terrain this translates into less deflection and less skiing effort (you can't cheat physics). However, the 1.1 are pretty comparable. My current touring skis are the Voile Objectives and the Dynafit Denali's. For my purposes, my lightweight touring skis, and my style of skiing, the 1.1's are more than adequate and the downhill performance is closer to the TLT7 than to original 1.0.
I will probably keep all three so as not wear down the new boots too quickly. The 1.0's will be a good training and Tues night race boot. The TLT7 is also a fantastic downhill, well-articulating, comfortable, and lightweight boot. I'll likely use these on deep powder days with wider skis when trail breaking is slower and there is a potential to get snow into the boots...or on really cold days. However, for those who are race /speed touring/scrambling oriented the 1.1 is possibly the best "quiver of 1" out there, and I imagine would be adept for most skimo applications.
I have had the opportunity to ski these boots on a pair of Ski Trab Magico skis and a pair of La Sportiva Vapor Sveltes in variable conditions that have included boot deep fresh powder, dust on crust, consolidated powder, sun crust, sastrugi and packed powder at the resort. I can report that they are just as effective as my former pair of boots, however, have satisfied my aforementioned goal of permitting more rapid ascents. I cannot comment upon their durability as I have only skied with them on just under ten occasions thus far. I am also unsure of how they will perform in spring type conditions. The only drawback that I have noticed is that the carbon cuff seems to comparatively abrade my ankle a bit more when sidehililng in steeper terrain. This makes sense as the boot lacks a traditional liner that extends to the top of the boot. With that said, I am optimistic and look forward to utilizing them as my sole touring boot henceforth.
Scarpa decided to call this the Alien 1.0 but this Alien 1.0 is a very different boot in a lot of ways than the older Alien 1.0. In order to make sure that you get the correct parts when you order spare parts for your old (or new) Alien 1.0/make sure that we are talking about which boots are comfortable on which skis/which boots fit a certain way/any other number of reasons, we thought an easy (though not perfect at all) way to differentiate was just to call this the Alien 1.1.
I have been looking at the weight of these and thinking of the possibilities! So am I dilusional or could these be good for week long powder touring trips?
Please note, at the beginning of last season Scarpa released a huge tech document that details the capabilities and guidelines of each boot in their lineup. They claimed that the Alien 1.0 (the previous Alien 1.0) shouldn't be skied on anything wider than 65mm underfoot otherwise they wouldn't warranty it. That being said, we have seen way more skiers "disobey" that guideline and use it on bigger skis than we have seen actually adhere to that standard. Just a thought to keep in mind. Not even sure if this boot is going to fall under that same standard or not, only time will tell.
Based on what I've heard from a handful of people (like superhuman Mr Teague Holmes' mentioned) there is way more than enough power behind this boot to really get a pretty sizeable ski going, especially in powder. I think it's going to be a ton of fun, I can't wait to get a pair.
I think the boot will fit a wider variety of feet while still holding lower volume feet just fine. I don’t think it’s wider, I think it does allow a little bit more room for high in-steps so I just added a little foam shim to take up space for my low volume feet.
It does keep the feet a little bit dryer with the gator.
And it’s way way easier to get in and out of with the intuition liner.
If you’re looking for a full on competitive race boot that can also handle proper mountaineering on a normal size ski, I can’t even imagine a better boot out there.
