SCARPA Alien 1.1 Boot
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.

How does the fit of the Scarpa Alien 1.1 compare to the F1 LT? If I know for certain that my foot fits very well in the F1 LT, will my foot also fit well in the Alien 1.1? And is the sizing of the boots the same?
4/14/2022
Hello Mike. I have an Alien RS, the same lower as the F1 LT according to SCARPA, and the Alien 1.1 both in the same size. The 1.1 is going to have a similar lower that is a bit smaller but also comes with a smaller liner and is definitely snugger. I would think if the F1 LT fits you well without any problems the 1.1 may fit you in the same size.

Hello! I have the Alien 1.1 from 2020 in size 30. It turned out that the boot was a bit small for my feet, lacking both length and width in the front. I had the boot shell blocked two years ago, but i still think it is at bit to small. Any experiance on how much theese boots can be stretched? I am no longer a youth, and have started to prefer comfort over race fit. I think my best bet would be a size 31 boot...
Any other suggestions for big, but lightweight boot? It seems that most boots in this category only come up to size 30.

Hi Erik, with SCARPA sizing, the 30 is also the same shell as a 29.5 (if it existed). The Backland Ultimate is a half size bigger and the shell can be heat molded to fit bigger feet.
Finally, for the first time in skimo history, there may be size 31.0 race boots next season: the Dynafit DNA and Mezzalama are planned to be offered in that size. Note those would also be available in size 30.5 with the same shell, and they are narrow and seem to run a bit small.

I'm a happy user of the old yellow 1.0 Alien (over 6 years and around 200'000 m at 90kg!). Does this newer version have the same sole lenght, so swapping on fix-drilled race bindings isn't an issue?

Hi Martin. These do have the same BSL as the old model. I'm sure you'll love the new boot and hopefully no need to redrill.
3/21/2022
Hi Martin, some folks who have made that switch noticed a difference in BSL (enough to want to add an adjustment plate), despite them being listed as the same. They come from different molds and there can be some discrepancies.

How will this compare to the LS Raceborg in terms of how big a ski it can drive?

Hey David, both are race boots and only designed to drive race skis. With that in mind, the 1.1 would be the better suited of the two to drive slightly bigger skis.

I am also curious about how to use of the 2 sets of "stick-on" pads that come with the boots. I would like to put some extra padding around my calf but am unsure if I should use just one or both sets of padding. Interested to hear what other people have been doing.
3/14/2022
Garrett, The two sets are different thicknesses, so you would use whichever achieves what you need for fit. They cover a lot of the cuff, you can trim and mix and match as needed.
Answer this question:
3/9/2022
Maybe a dumb question, but I can't find any info in the owner's manual or on Scarpa's website or here about use of the 2 sets of "stick-on" pads that come with the boots. I assume they are for the liner as a sort of ankle wrap if needed. Thanks in advance for any guidance.
3/10/2022
Hi Dave,
The foam pads that included in the box are intended to help with filling out areas that are too high volume for your foot. For example, adding foam behind your calf in the cuff to ensure a more snug fit in the cuff area. Another option could be using that pad in the ankle/heel area to increase heel hold. If you have further questions, feel free to reach out to help@skimo.co!

Hi, I already have the pdg2 size 26 and I’m looking for another boots. My feet are 107cm large and 25,8 long. What is the best size for me and to you think this boots are large enough! Thanks
3/7/2022
Hi Marc-Andre,
The PDG2 has a pretty high volume fit for a race boot. Also, based on your foot measurements, it looks like you have a foot on the wider end of the spectrum. The Alien 1.1 has a narrow last width, and would not be the best pairing for your feet. If you are on the lookout for a new set of skimo race boots, I would check out our Boot Fitter tool!

I have size 29 in these and right foot is perfect, but left could use just a touch bigger liner. Is it possible to get a 29.5 liner? Do they make that and how do the shells break on these boots? I think the 30.0 would be too big.
Thank you
Thank you
2/19/2022
Hey Kevin,
If the boots are brand new, I would suggest heat molding the liner with a full toe cap to give the toes on your left foot a little space. Scarpa uses intuition liners designed to be heat molded even in their race boots, so if your toes are just a bit snug, a heat mold might just do the trick for you. In these boots there are no half sizes, so you would have to jump up to the 30.0 if you need more than a few millimeters of space.

IS IT POSSIBLE TO USE A TRADITIONAL LINER (THE INTUITION FOR EXAMPLE) ON THE SCARPA 1.1?
2/8/2022
Thanks for reaching out, Pau. For this boot, you'd be better off with a Palau Ultralight Race Liner, which is a bit more traditional than the bikini style liner that comes with the boot.

Hi Pau, the cuff flaps aren't long enough to encompass an Intuition liner which is really thick in the cuff. The cord will kinda get caught with the flaps going the wrong way.

Hi. I wear a size 26.5 in the Alien RS, what size should I get in the Alien 1.1?
1/17/2022
Hi Robert, to our knowledge, the RS was only available in whole sizes. You would be the same size 1.1 that you are in the RS, noting it's a touch narrower and lower volume so has the potential to not fit if you're tight in the RS.
Answer this question:
I have used the first 1.1 version and now the new color scheme which actually made significant changes to the boot itself.
I had issues with the cord clips on the first version. Specifically how they would catch on the carbon cuff and get bent out of shape. The new version seems to fix that. The clip is much stronger appearing and I have been unable to get it to catch when rubbing the boots together.
The gaiter also seems to be more durable. I had issues with wear on the gaiter and mild tearing of the velcro, but the new version improves the velcro where I don't expect it to tear. One problem with the gaiter however is that it is less stretchy and so makes boot entry and exit a bit more contorted.
Overall a big improvement and worth the upgrade

Hi TZed,
Thanks for your feedback. May I ask specifically what versions are you referring to ? Is the first 1.1 the one with the yellow boa and the new color scheme the one with the orange boa and blue/orange on the sides ?
Would you recommend the latest one ?
Thanks !

I do recommend the blue and orange version. They have been going strong for me

Comment on this review:
For their intended use, they're an amazing piece of technology
I pushed them, skiing 90mm skis in the summer in couloirs. For this purpose I was much happier in a bigger boot, at least an Alien RS. I felt the lack of material in the front of the 1.1
The total lack of ankle resistance on the up is amazing, but the lower poked me in my Achilles if I took too large a stride
Overall though, for what they are, it's amazing what they can do. A little taste of the future, I think

Hey crew! I've had a pair of these for two years and I LOVE them, but I have a pair of liners that are absolutely toast. Do you know anything about the replacement liners for the 1.1s? I can't find them on Scarpa or on your site. Do they exist in the US?

Hi,
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?

Hi Kroman,
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!

Hi guys! I understand these boots comes without a footbed. Are they intended to be used without footbeds, or do you recommend to get some custom ones?
10/13/2020
Hey Stones, basically it all depends on how well the boots fit your feet. If you have them sized a bit tighter as some racers do, there might not be all that much room in the boot to include a footbed which could possibly be why Scarpa didn't add one. So in essence yes, you can include a custom footbed in the boot and depending on the fit it would not detract from the boots overall functionality.

How does the Alien 1.1 compare for regular lightweight ski touring and technical ski mountaineering (non-racing) compared to the Alien RS? I have a pair of Alien 3.0s for racing that I really like, but I'm hesitant to do big days in the mountains with them. I'm looking for a boot that's still really light and can drive a 90-waist ski (Dynafit Carbonio). Is the Alien 1.1 too 'race-oriented' or will it excel for this use?
2/14/2020
Al,
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 haven’t skied the alien RS but I also race in the alien 3.0 and use the alien 1.1 as my touring boot (mainly with a 89mm underfoot ski) and find it to be a great lightweight touring boot with adequate warmth, coverage, durability and ski performance.

Have you had any problems with the medial side hooks? I bent mine in my first outing in an accidental scuff of one leg against the other. I was able to bend it back, but i’m sure this will happen again and that hook will eventually fail. It’s in a pretty bad spot and could likely be moved back and out of the way, much like the lateral side hook. Anyone have experience with this? I can’t be the only one to experience this. Any official Scarpa-endorsed fixes? Thanks!
2/9/2019
Hey Justin,
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!

Hello, has there been any solution to this issue? I have heard of this problem from multiple sources. I am a little hesitant to purchase these boots because of this. It seems like catching this hook during a race would be a likely scenario.
-Thanks
-Thanks
11/16/2019
One thing that has worked reasonably well for me it to run a small strip of duct tape over that spot on each boot prior to each outing. It smooths the edge and seems to prevent catching the hook. Not a great fix, but pretty quick when gearing up.
11/16/2019
Yes, it is possible to catch the medial cord hooks with your opposite leg and cause bending. Usually, it can still hold the cord even after several blows. It works to bend them back, but repeated manipulation may lead to failure. We have replacement hooks and rivets for that situation.
11/16/2019
Thanks Justin! Would love to see a photo of how you apply the tape.
8/28/2020
FYI I have also had this problem three times, twice bent it back and the third time had scarpa replace the hook. I wouldn't worry about it in a race unless there was lots of running. It has always happened when running/fast walking mountaineering
