SCARPA Alien 1.1 Boot

1) Out of the box I noticed the cuff hardware was very loose on one side of one boot. Attempts to tighten this screw+nut mechanism have not worked. Any tips to tighten this mechanism or is it being quite loose normal?

2) Any recommendations for a gaiter for winter use to keep snow out? I see the old alien one listed on the site. I have the 27 mondo boot and it looks like that old model only has up to 26 listed as fitting.

Thanks!

I currently have a size 28.5 and struggling with the heel pocket on these as i cannot get away from heal burn when the pitch goes up. I've tried insoles to lock my foot in place, ground out the back of the shell to try and round it out and smooth it, to no relief.
Any thoughts on getting this to fit better? I'm curious if a larger liner (since I think the 28.5 also is a 29?) and maybe the smaller liner is not fitting the foot well? Any suggestions before I drop another 1K on skimo boots that just dont seem to fit and no options in my area to try these on. Thanks!

hi folks, I'm a hardboot splitboarder coming from a modified Atomic Backland Carbon. I have a pretty wide foot and Scarpa mountaineering boots usually fit me like a glove. I ride a size 28 in the Backlands, would I want to size these any differently? Any other thoughts on using these for skimo objectives and/or touring use? I'd keep the backlands for really cold days, but would also consider grabbing the full length Alien liner to add some warmth to these if it would expand their use. Thanks!

These boots are amazing. I have a Scarpa foot. I fit well in the Alien RS before I got these. The Boa dial on these boots is a big improvement over the Alien RS. And, I can get the cord to lock down the rest of the boot plenty tight. I use them primarily for skimo laps, but I also put them through some serious ski mountaineering objectives. The carbon cuff is incredibly stiff laterally, and the fore-aft flex is better than you'd expect with a lightweight boot. I have a really narrow, low-volume foot, and the forefoot is a bit roomy for me, but that's true in any boot I own. If you like Scarpa boots, these things can't be beat for a skimo race boot or ultralight mountaineering boot. Do it!

Will the size 27 fit a 27.5 linear? I know some old aliens the shells were sized 27-28.

Thanks!!

Would it work to put scarpa alien full length liners in the alien 1.1? I own the 1.1 and the plastic on the sides of the carbon upper rub against my calf causing discomfort.

Hello, I currently have a pair of sz 27.5 PG Race 400 that are great on the width but a bit small on length and volume. I make the boots work for racing but am likely sizing up slightly and adding a training boot to the fleet. How would the forefoot width and volume of Alien 1.1 compare with the PG Race 400/Dynafit DNA?

Try these boots! When I first got these, I'd never skied anything other than 4-buckle boots. Wow, what a difference! The lighter weight is very nice, but the unimpeded range of motion is game changing. And of course transitioning with a single lever throw is important for racing, but it makes touring that much better as well.

I was worried that these wouldn't ski well, but I've been pleasantly surprised. Yes, there definitely is a difference between these and a "beef" boot. But the tradeoff downhill is very manageable and is much less than the improvement in uphill performance. In addition to racing, I've started picking these for longer touring and ski mountaineering missions. They're probably at their best driving a ski 80mm or narrower, but I felt that they also did a pretty good job with a 96mm ski.

How do they compare to the Pierre Gignoux Mountain boots?
I would want them for daily training, as well as for longer, more traverse-like and off piste, projects.

I already have a Scarpa Alien 3.0, but I find them a little bit too cold and the lack of waterproofness annoying. Also, I hope to get better downhill skiing performance, especially in more technical terrain, with the new boots, but I still want them light enough for my daily training.

The mountain is a little bit lighter, I think, and the downhill should be more controlled too. Are there any cons of choosing the Pierre Gignoux over the Scarpa?

Do you think the approximately 150g more (compared to my Alien 3) per foot make a huge difference in training?

Will my CAMP XLC fully auto crampons work with these? Are they compatible with all crampons, or do I need something with the lever in the front (Grivel Skimatic or similar)? Seems like the older Aliens' walk/ski mode got in the way of the heel lever of some crampons, and I'm wondering if that's the case with these new ones?

I skied a 29 in the old Scarpa 1.0 from 2018 or so. But the boot was just marginally too small for me. I'm good to go in the Dynafit TLT6 @ 29 with a thicker liner (green or black boot) . And good for skiing only in a 28 (green) if I squeeze into them with a lwt/thin Dynafit liner.

I've tried the Scarpa F1 LT in a 29. Too small and a poor fit for me. Care to offer any feedback on getting a decent fit from a Alien 1.1 in a size 30?

I love these boots and use them regularly on skis from 65mm - 85mm. They are a much better ski boot than the older Yellow version although I still prefer the older ones for racing actually, but these newer ones are a great all round Ski Mountaineering boot. However, in the past 2 weeks the ski walk level has snapped off the boot very easily, the screws seem to just rip out. This was on the first turn on easy angle slopes on a race ski. Luckily I was not in any real danger spots but curious to hear if this is a problem anyone else experiences? First time it was just the screws that blew out, got it repaired then the second time the screws ripped AND the lever snapped!

For the record, I am 180, 68kg.

How do these fit compared to the F1 LT? I wear a 27 in that boot, and after breaking the liners in, they're pretty comfortable and just wide enough for my toeline. In terms of length, my toes are just touching the liner, but it's really perfect; no more and no less length.

The only major fit problem I have with them is the midfoot/arch area, which feels a bit aggressive to my relatively flat foot, and if I run or otherwise do skimo intervals, my arches get really sore for a few days.

Since these seem more narrow, I'm wondering if I should maintain the F1 LT BSL ~295mm and size up to a 28 here, unless that might give me too loose of a fit? Foot length is 268mm, and width is 102mm with thin race socks on.

I have a pair of Alien 1.1 circa 11/19. They have pretty light duty. I don't race and use them mainly for spring and summer corn skiing. The BOA snapped on my tonight during my dog walk tour. I've had 4 failures like this over the years, all in tour mode, 2 from the RS, 1 from the Dynafit TLT X and now from the Alien 1.1. What are my options to replace it? There is a snowboard shop in town that might do the work if I can't figure it out.

Can this boot be punched out at all? I have hear mixed opinions about whether or not the plastic can withstand being heated and punched

I've recently become a convert and I want everyone to know! When I bought these, I was very unsure if I was going too far (after all, if you go too light, then you'll find out the truth about how good of a skier you are, right?). I read the reviews and was convinced that these perform better than you might expect, and it's all true. Actually, funny story from my first outing in these, I've been rocking some old hard-charging Scarpas that are only slightly lighter than downhill boots (and perform just as well), and because they're so stiff, I've never used walk/ski mode, I honestly can't tell the difference. My first run in the Aliens was so exponentially disastrous, I feared I was in really big trouble and questioned all of my decisions. I skinned back up and on my second lap, I thought, oh I should probably flip these to downhill mode! And what do you know, flipping the switch takes them from a soft nordic-equivalent boot to a downhill beast with total control.
I love the BOA, I love love love the weight, I heat molded and they're uber comfy . I think my only gripe is the walk/ski mode bar when it's up (walk), my pants get caught on it, and also when I'm ready to switch, I have to pull my pant leg up to the top of my boot then pull it back down, which in the spring I'll probably just leave pants rolled up but in powder I think it's particularly important to keep some of the snow off these boots since it's hard to imagine they're fully waterproof (although I haven't had wet feet yet)
One comment on sizing if it helps anyone because these seem small to me compared to other scarpas, my foot is 22 centimeters, I generally wear a 23.5 mondo (in other Scarpa boots), or 37.5/6.5 in running shoes (sportiva, scarpa, salewa), 37 in sportiva mtn boots. These I got a 24 and they fit perfectly after a heat mold (with the lightweight Darn Tough merino ski) but there's no additional room for thicker socks when it's cold.

Hi,
I currently have the Fischer Traverse CS Boot in 25.5 (great fit) and I was wondering how will this compare with the Alien 1.1 in size 26?

I have an old pair of Aliens (purchased 2015) -- neon yellow version with plastic riveted on in the bending areas of the cuff to reduce snow/water entry. I've loved the boot's weight and range of motion. And they ski just fine for my old-school style of skiing (lots of turns, not particularly fast). What I haven't liked is how wet the boots get inside. Obviously some of the moisture is sweat but most of it is melted snow that wets out the liner to the point that my socks are often wringing wet. This is tolerable for day trips but far from desirable for multi-day trips.

So my main question about the Aliens 1.1 is whether the gaiter effectively blocks outside moisture from penetrating the boots and wetting out your feet. I want a very light boot that simply has me managing my sweat.

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?

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.
