August to October is an exciting time for ski shops all across the country. Each year, a handful of products really stand out*, and La Sportiva's boot was one of the most anticipated. The Skorpuis CR boot was meant to replace the Spitfire, and man did La Sportiva nail it. With a 68 degree range of walking motion and the smooth Spider ratchet closure system, the Skorpius goes up as well as it goes down (some might say it does so even better than its forebearer). Now, you don't have to compromise on performance or lug an ounce more than you need to into the backcountry -- The La Sportiva Skorpius boot is all you need for BC glory.

* Even though we told them not to, the guys in the shop did bring cake and ice cream to work the day that these arrived. We apologize for any stray frosting or sprinkles, we tried to get it all, but a Costco cake thrown in the air does leave quite the mess.

  • The SWING-LOCK ski/walk closure system is easy to use and stays in whatever mode you want it to.
  • Ramped toe inserts mean that Ski Trab Titan bindings can be stepped into without depressing the lever.
  • This boot has 68 degrees range of motion (33° back and 35° forward) for your walking pleasure.
  • A La Sportiva GripGuard boot sole makes rocky scrambles feel secure.
  • Compatible with tech, AT frame, and the unique TR2 bindings.
  • Made in Italy.

Question from Brian
 
I may be comparing apples to oranges a bit with this question, but how do you think this boot stacks up with the Dalbello Quantum Free130 and the Fischer Trans Alp Pro? These are both on my radar this year. I have Atomic Backlands Carbons which are fine, but looking for a bit more power while keeping the weight down and retain good range of motion. My Freeride boot is a Technica Zero G for reference.
10/11/2021
Answer from Julieana
 
Hey Brian,
You're not comparing apples to oranges at all! All three of the boots you mentioned are designed to fill that gap between lighter, uphill-oriented boots like your Backlands, and freeride boots like the Zero G. I would say this boot in terms of performance is the best of the "best of both worlds" category, as it is exceptionally supportive and stiff when in downhill mode while still having a vast range of motion in touring mode. The real question will be if it fits your foot, as it has quite a low instep height that can be really uncomfortable for a lot of people. If you found the Zero Gs and Backlands to be pretty comfortable, there's a decent chance you fall into the category of people whose instep is too high for this boot, so I would definitely try them on first if you can.
10/11/2021
Answer from Brian W
 
Thanks Julieana! Actually, the Backlands are a bit roomy over the instep and I took up instep volume in the Zero G’s with a high volume tongue in my medium volume Intuition liners, so the Skorpius may not be too bad a choice. So you are saying it has a lower instep than the Quantum or Trans Alp Pro?
10/12/2021
Answer from Julieana
 
Yup, that instep is definitely going to be the snuggest/lowest of the three!

Hey guys/gals - Do you know if Sportiva did anything to fix the breaking tongue problem on these? Definitely the best boot I've had, but that broken tongue (and subsequent limited warranty inventory) was a real bummer last year.

Gracias! Or, should I say, Grazie!
10/8/2021
Answer from Jeremy L
 
Thanks for the question, Grant. We have received a response from La Sportiva and it looks like all the Skorpius boots that came out of the factory, starting with the 20/21 season, were all updated with a more flexible plastic material to avoid breakage.

Question from Peter Cleghorn
 
Hiya, How does the Skorpius, compare to the La Sportiva Solar? For ski down, which is stiffer and by how much?
Many thanks
8/20/2021
Answer from Zak M
 
Hey Peter, the Skorpius will have a stiffer flex and feel like a burlier boot on the way down. La Sportiva gives a flex of 100 for the Skorpius verse a 90 flex for the Solar. Let us know if you have any other questions!

Question from Jordan
 
I don't feel like my F1LT can get 100% of the power out of my Mythic 97 -- would these be a better pairing for this 1450g ski?

Also, what's the weight of the 26/26.5?
5/5/2021
Answer from Zak M
 
Hey Jordan, the La Sportiva Skorpius is definitely a fair amount stiffer than the F1 LT. While it may not be a night and day difference, one could say more like a night and dusk difference so to say. The Skorpius is more than enough boot to drive a ski like the Mythic for most people though. If you were looking for a drastic difference in stiffness you may want to check out a boot from our freeride touring boot category.

In response to Tristan's suggestion to use the Camp Skimo Race Crampons for the Skorpius--would I need to buy the Dyneema linking strap?

Hi Sally,

The Camp Skimo Race Crampons will work just fine with the standard metal bar. The Dyneema linking strap is mostly for shaving grams!

Question from Sally
 
I've read that some people have had trouble with crampons with these boots because of the really rockered soles. Any recommendations for (aluminum) crampons that works well with these?
4/5/2021
Answer from Tristan M
 
Hi Sally,

The rocker on the Skorpius can be tricky. However, a lot of ski mountaineering crampons have been designed to accommodate boots with rocker. For example, the Camp Skimo Race Crampons have an adjustable toe bail to accommodate various toe welt heights. Additionally, they are all aluminum, and quite light!

Another great all-aluminum option for the Skorpius would be the Petzle Leapord. The Cord-Tec attachment system gives this crampon a lot of flexibility to fit a wide range of boot soles.

First year using these boots and I'm loving them. They feel clunky in your hands - lots of layers of plastic doing different things. On my feet - 10/10. I've skied them in all snow conditions and they're solid steel. Plenty light on the uphill with great mobility. I've had them in crampons and Verts and been flying uphill. I'm still working on optimizing how I want to use all the options on straps and buckles but so far they've done everything I've asked and are still looking brand new.

Question from Tom
 
I believe 30.0 and 30.5 have the same shell? How is the difference in size achieved? A thicker liner or an additional insole? Thanks!
3/18/2021
Answer from Brett S
 
Thanks for your question, Tom. The 30.0 and 30.5 are the same shell, however, they will have different liners to achieve the "size" difference. The 30.0 will have a slightly thicker liner than the 30.5. Please let us know if you have any other questions!

Question from Ben
 
Looking at these boots to fill the elusive 1200-1300g fast walking+hard skiing slot, and they look really good. I've got a low volume foot with a small ankle. I've tried the F1 which has too much volume and a low cuff, and the Movement Free Tour which has a pretty good fit but would prefer a lower instep height and a higher cuff. Is the cuff on the Skorpius much higher than on the Free Tour?
3/12/2021
Answer from jbo
 
Hi Ben, the instep should be dialed for you on the Skorpius. As far as the cuff height, it does feel taller than the Movement, if just because of the positioning of the power strap.

Charlie Avis (downright abused product)
 
These boots are awesome. They walk well, they ski well, and they climb well. I previously had skied the TLT6, and these boots are in another league of downhill ski ability (I typically ski a 95mm underfoot), while feeling just as good on the uphills. I have only one gripe, which is that the front plastic tongue is not durable, and both broke on me at the flexion point. If La Sportiva can figure out a better system with the front tongue, then these boots would be all time greats. The upside is that the broken tongues actually made the walking performance even better! With a bit of stiffness lost when descending. Also related to the front tongues, is that sometimes the liner tongue slips to one side on long tours, and the plastic part jams into my shins. I remedied this with a new pair of liners from Palau with a lace up front.

There is some debate as to what weight class these boots fall into (not as light at the Alien RS, not as heavy as the Hoji), but I think that the weight is a bit deceiving. These boots don't feel heavy because of the good articulation and thin profile (and believe me, I am a weight weeny, so I don't say that lightly). Any marginal inefficiency due to weight is completely offset by the stability on descents. I've skied 50 degree breakable on these things and was very thankful for the stiffness and progressive flex they provided.

So TL:DR: this is a 5 star boot if they fix the durability/comfort for that front plastic tongue.

Question from Don
 
Hey guys - what's the story with the weight of this boot? La Sportiva and other sites all have this boot around 1000g, whilst your measured specs suggest a fair bit more than that...is this common, and what's the approx weight for the 26.5s? Is there much between the F1 LT and this boot in terms of weight and performance?
2/5/2021
Answer from Julieana
 
Hey Don, we take our weight measurements very seriously here at Skimo Co, so the weight on our site is what we personally have measured with great attention to detail. Most sites just post what La Sportiva has posted, which we don't necessarily know how or why they get the number they get. We have noticed some companies may measure the weight of the shell alone, no liner, which can cause some confusion--hence why we weigh everything in-house. The F1 LT is significantly lighter than this boot, but this boot is significantly more rigid, stiff, and aggressive in downhill mode. the 26.5 is approximately 1180g.

This boot is pretty special with just a few nitpicky things I don't care for. This is definitely a real boot and can ski anything you want unless youre in the freeride world tour. I sold my ice climbing boots because this climbs ice better than those. Fit wise it is a tad strange in the sense that it is moderately wide in the forefoot with the best heel cup I've used (seriously scarpa why do your heels suck) and I would classify it as high volume EXCEPT for the instep area which is medium to lowish and unfortunately it appears that normal bootfitting tricks can't help this because of the way the tongue is built into the boot (unless u want to bust out the dremel.) The liner is nothing special, will sub out with pro tours eventually. The lockout is awesome, I prefer it to the vertical throw style. I think the lower shell closure is gimmicky and trying to reinvent the wheel if I am being honest but it works so far, just due to material size long term durability is probably suspect yet appears very easy to replace the thin wire. I personally think it just needs a over ankle rachet (as I believe all boots do). I do feel like the optional power strap on this is more effective than other boots I've tried. It walks, runs, and climbs amazingly. Trab quickstep is also amazing. Comparison wise id say it skis maybe 85-90 percent of my Hojis but it walks more like f1 lts. So a perfect contender for the elusive 1 boot quiver. Another complaint is the cuff rivet, wish they would have followed new industry standard of making it user serviceable like on scarpas and atomics. It also says it has 3 forward leans but I see no way to adjust that. You can remove the little yellow spoiler but that in theory would only give you 2. Speaking of forward leans I also wish it went the direction of scarpa and had a less than 10 degree option. Once you go upright it's hard to go back. It punches super easy, did all my usual bootwork with a heat gun no problem.

All these little nitpicks aside I do think this is the best 1 boot option available and even has a spot in quivers (for me taking the place of the f1 lt in between race boots and hojis). La sportiva hasn't impressed me in a while but these boots are a home run. If they fit you, as with anything, they are an excellent minimal compromise boot for someone who doesn't mind a few extra grams for a helluva lot more boot. I'll gladly take the extra weight vs the f1 lt for the improved skiing and alpine climbing ability (how un-skimo of me). Now is a special time where if you dabble in the dark arts of traditional mountaineering, ice climbing, alpine climbing etc, you may only need 1 boot...

Pros: punches above weight performance wise, outskis anything near or below it's weight. Walks as well as a lighter boot, skis like a heavier one. Light enough, stiff as most mortals need. Trab quickstep

Cons: cuff rivet joint (pressfit vs threaded), over engineered lower closure, possible durability concerns, not much ability to modify boot fit in regards to instep, doesn't really have adjustable forward lean. Non primo liner.

Reply from David B
 
The yellow plastic forward lean shim has 2 attachment clip slots. I have yet to verify but it seems to be, according to specs: top slot (middle lean 14 deg.), bottom slot (forward lean 16 deg.) and the 3rd setting is to remove it entirely (more vertical 12 deg.)

Question from Phil
 
I recently switched from a pair of Spitfires to the Skorpius, using an older pair of Speed Radical bindings. The toe of the binding does not want to release when using the new Skorpius boots. It has been difficult to get out of the bindings when taking the skis off. Is this a known issue? Any thoughts?
Thanks!
1/14/2021
Answer from Brett S
 
Thanks for your question, Phil! This can happen with new boots that have a bit more rubber protruding under the toe that inhibits the wings of the binding from fully opening. It is possible to conservatively shave some off the rubber responsible to allow the binding wings to fully open, which should solve the issue. Please give us a call or send us an email at help@skimo.co if you need some guidance on how to do this!

Question from Jed Koljonen
 
I purchased a pair of these boots last year and everything works great except the upper strap won’t stay latched when loosened and hiking or skinning. I was wondering if you knew of a hack to keep the metal clip in the plastic notch when hiking/skinning. Or sure if this is a known problem or just me. Any info would be appreciated. Thanks.
1/13/2021
Answer from Teddy Young
 
Hey Jed, thanks for reaching out! Before skinning uphill, tighten the strap and buckle it into place, then open the buckle back up. The tension on the strap should cause the black plastic piece with the mountain logo to click into place and remain secure.

Question from Anthony O
 
I saw all the comments about this being almost unique in the category as far as punching above the weight class, which also seems to be the consensus for the f1 lt (which I own). Does this ski as well as a hoji pro tour or a tecnica zero g? I have hoji pro tours and hojis frees (which are really just for slackcountry with non skimo converts) and am thinking this could be a good multi-use daily boot for days where I want more performance than f1's but don't want hoji frees.
1/12/2021
Answer from Julieana
 
Hey Anthony, these will not be quite as stiff as the Hoji or the Zero G, but they are noticeably stiffer than the other boots in the 2 buckle touring boot category. It could definitely be a nice middle ground between your F1 LTs and your Hojis.
1/12/2021
Answer from Jeff
 
Anthony, Yes it is good for a one boot quiver. Does it ski the same as a 4 buckle overlap boot, not quite. The F1 LT is also quite powerful for its weight. The Skorpius is just a bit stiffer and has a more progressive flex. Everything is subjective.
Its fit is comparable to the Hoji for those looking to lighten up.

Hi Sam,

If you have any questions on boot size, fit, or performance, I recommend that you use our boot fitter tool at this link: https://skimo.co/boot-fitter.

Answer from jbo
 
Hi Sam, the Skorpius 30.0 is about half a centimeter longer, as it shares the same shell with the 30.5. The Maestrale 30.0 shares the same shell with the 29.5. As for whether the other fit characteristics (width, volume, calf, ankle, etc) will work for you, definitely visit our online fitter!

12/14/2020

Hey Bob, yes the Skorpius is compatible with the Tecton binding. However, we have noticed that with different boot sole lengths the rocker underfoot can create extra friction with the toe piece and could potentially affect the consistency of release.

Would you feel these are enough boot for wider freetour skis, like the Alchemist Wailer 112, Katanas or 4Frnt Hojis (latter two also being 112mm waist) for dedicated backcountry, powder, not-too-sendy skiing? Looking to move off of my Vulcans to something lighter with more ROM, but still robust enough for those types of skis, and light enough to replace my TLT6-Ps when using my 90-mm spring/13-14er ski.

Dub_xion, thanks for reaching out. The Skorpius is a very capable boot and should have no problem driving either of those skis. You will be pleased with its performance both hiking and skiing!
