La Sportiva Skorpius CR Boot

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?

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?

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?

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.

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!

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?

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.

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?

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.

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!

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.

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.

If I wear a 30.0 in Maestrale would I be the same in these?

Is the Scorpius compatible with the Tecton binding?

Any idea when 27s will be back in stock?

How does the width and instep volume compare to the backland carbon?

Thanks!

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.

how does this boot's downhill performance compare to the:
- Atomic Backland Carbon
- Scarpa F1 LT
- Dalbello Quantum
Asking for future me this upcoming season in a pair of slick ~1000g boots.

Im a newbie to this boot class...going from soft boots on my spltty to a skimo boot and the phantom system, how would you rate this particular boot ? will it be an easy changeover for me or is it too stiff and therefore too great a jump? is there a boot that you'd think is a better option? the TLT6, etc??

How do these compare to the first generation La Sportiva Spectre for fit in terms of size and fit? I currently use stripped down Spectres with the power strap and 2 buckles removed, size 26.5. I have very muscular legs so want to know if the boot accommodates large calves?
