The zombie Alien apocalypse we really wanted has arrived, and it's looking to be a good time. Updated and back from the dead, the SCARPA Alien ski boot got some renovations that improve upon the previous model. Still the prime choice for the skier who sits on the fence between skimo racing and steep and deep backcountry touring, this Alien is frighteningly light and nauseatingly powerful. With the ski/walk lever positioned in walk mode, this boot has a wider range of motion than your ankle does. While in ski mode you'll have the confidence of a much younger, more limber version of yourself. A simplified closure system lost the velcro powerband, cutting a couple of precious grams so you can fly uphill, moving so fast you'll likely be confused for (you know I'm gonna say it) an Alien.

  • Weighing in at well under a kilo per boot, the updated Alien can easily be considered a competitively weighted race boot, while also being a reliable backcountry boot. Bonkers.
  • A Boa closure system serves the bottom shell of the boot, eliminating pressure points that buckles sometimes cause in favor of the Boa's smooth and even compression.
  • Intuition Cross Fit Tour Lite liner (whata mouthful) is comfy cozy right out of the box, but can be heat molded to your foot with a prescription from the boot doctor.
  • A slightly narrower last (99mm) makes this a great choice for the narrower foot, or perhaps just a more performance oriented fit.
  • Keeping with the extraterrestrial theme, a Vibram UFO sole adorns the lower extremities of this fine piece of Italian engineering.
  • As mentioned in the description above, this boot has a wider range of motion that your ankle probably does-- 72 degrees.
  • Adjustable settings of 9 and 13 degrees of forward lean offer customization for the tinkerer and performance skier alike.

Question from Gabriele
 
Hi I'm searching for a boot to match my Salomon slab Xalp skis but I really don't know what to choose besides these alien and the alien rs! I will use them mostly for speed touring sessions up and down the ski slopes and/or for easy touring days (no steep couloir or deep snow). I will like to find a boot capable of high performance on the uphill and no holding back on various kind of downhill.

Last point: I've got a 25.5 cm feet so I guess I should choose size 26 ?
Thanks for your reply!!

Answer from Cole P
 
Hey Gabriele, these boots ski great and provide a great progressive flex. The RS has the carbon-infused Grilamid on them that stiffen the boot up significantly, but doesn't have the same progressive flex that you would feel on the Alien. With not much weight penalty, I would focus on how I want the boots to feel. Alien if you want to feel the flex of the boot and the RS if you want to ski hard in the front of the boot. For the sizing I would recommend size 26. If you have any more questions feel free to email us at help@skimo.co.

Question from Not Trace Leches
 
How’s the power on these bad boys? Wet noodle, beefcake, or somewhere in between? Thinking I might like a ski wider than 80mm at some point, but there’s not way you’ll see me in heavy boots.
3/30/2020
Answer from Brett S
 
Thanks for the question "Not Trace Leches!" The power on these is as you would expect from a race boot. You can click into a pair of bindings mounted to a wider ski with these boots, but if the conditions were less than ideal (i.e. not hero snow) the ski would probably be skiing you vs the other way around. If you after the supreme tourability of a race boot, with a little more "umph," check out the Alien RS (also from Scarpa).

Answer from Not Trace Leches
 
So somewhere in between, got it. How’s the fit compared to an Alien RS? How about compared to the new Alien 1.0? Looks like more or less the same lower to me. Is the shell punchable? The toe box in the Alien RS ended up being a bit too round for my square hobbit feet and it caused its fair share of issues. I punched the hell out of it but wasn’t able to get enough movement. It’s my own fault though, I thought I was being cool by wearing a size smaller than I needed in a boot that’s not technically punchable.

Answer from Brett S
 
It would be a safe assumption to say the fit between this and the Alien RS is extremely similar. It sports a carbon infused Grilamid lower and thus would still probably not be "technically" punchable (unless your Mike Tyson, of course).

Question from Milan
 
Just wondering if the 1.0 and new alien shares the same bottom shell, only difference being the upper cuff Carbon vs Grilamid? Another words the alien 290 fits best would 1.0 be 290 as well
2/15/2020
Answer from Jeff
 
Milan, The Alien 1.0 (or 1.1 as we call it) have the same shell. They also have a full liner.

Question from Shaun Sutner
 
If I'm normally a 27.5, and have a foot that's on the narrower side, should I go with a 27 or 28? Thanks!

Just getting into Skimo training and these are my favorite Ski Boots I have worn! I do a lot of running in the mountains on my Salomon S/Lab shoes (Size 9) and the Aliens (Size 27) fit my narrow feet in a similar way. I have not tested them too much on a boot pack section but feel they would perform greatly. I like the flexibility in walk mode and quick flip of the buckle into ski mode. I have tried both forward lean angles (9 and 13) and feel like I can be somewhat aggressive on the downhill with such. Lastly, the Boa and Cord system make this a simple yet effective boot to wear while touring or racing. The boots pair nicely with my Voile WSP's.

Question from Dave
 
Because of the larger liner does this boot have much more ankle friction than the Scarpa Alien 1.1? I know the mobility is listed as a few degrees less (72 vs 75) but I'm more concerned about the ease of rotation.
12/19/2019
Answer from jbo
 
Hi Dave, yes, the 1.1 has a backless liner (it's just a tongue above the ankle) so there is no resistance to backwards articulation. With this Alien, you have to flex the liner which, while flexible, is not quite as easy to bend as essentially no liner. On the flip side, this boot will have more of a back seat!

Question from mkg
 
Follow up question on my "review" above, which I mistakenly didn't submit as a question...

Looking at my f1s, it looks like Scarpa just used a "picture hanger" d-ring and attached via the hex bolt on the boot. I have some of these d-rings and it looks like a simple mod. question about removing that bolt, tho... is it riveted? do you think I'd need a longer bolt to make it work? asking before I start twisting things, in case you have the info. :)

Thanks.
12/14/2019
Answer from Jeff
 
MKG, that will work. It is a hex bolt into a threaded T nut. As long as the connector on your D ring is very thin, it should be no problem.

love these. question: for the occasional resort day or race requiring them, what do you recommend for attachment point? i can make the cord work, but it’s awkward. my f1s have a d-ring. anything like that available aftermarket? i could also attach some kind of extender to a ring off the boa button, but i don’t love that idea in a fall. i guess i could extend a cord... off the cord. i’m using atk leashes. thanks!

Erik, Both Teddy and myself wear a size 8.5/9 shoe and have a size 26 Alien RS. The whole liner is heat moldable.

Question from Chris
 
How do these compare to the Alien RS?
7/18/2019
Answer from Teddy Young
 
Hey Chris, compared to the Alien RS, this boot will have a shorter cuff height, shorter BSL, and softer flex. It will have the Alien 1.1 lower and a plastic cuff. More of an entry level race boot, whereas the Alien RS has slightly more beef for “race plus” lightweight touring.
