Gear Review | La Sportiva Skorpius CR

Lightweight high-performance touring boot

by Lorenzo Rieg • 02/22/2020
La Sportiva is strengthening its range of ski touring boots for the current season with a very lightweight model that bridges the gap between ski touring boots and normal, ascent-orientated boots. We have already tested the new Skorpius extensively.

First impression

The boot is of course very light and its construction initially looks almost like a ski touring boot. However, the high-quality and not really ultra-lightweight liner, for example, shows that the Skorpius is definitely aimed at normal ski tourers. Another interesting feature is the locking mechanism that fixes the shaft in downhill mode. Here, the lever is closed sideways and thus remains very stable despite its simple construction, meaning that movement of the shaft is practically impossible in downhill mode. Adjusting the front buckle by moving the cable in the shell takes a little getting used to - certainly not something you want to do at the summit. Careful adjustment of the boot at home is therefore recommended.

It is also worth mentioning that the Skorpius fits into the Trab TR bindings by default, making it one of the very small group of ski touring boots that can really be used with any touring binding. Furthermore, the Skorpius' carbon-reinforced shaft is made entirely from bio-based plastic - to my knowledge, this is not the case with any other ski boot.

Testers and test conditions

I'm a good 180cm tall and weigh about 75kg. I ski a lot, mostly on ski tours. I'm mainly interested in downhill skiing, so I almost always use wide skis and relatively stable boots. I usually use the Scott S1 Carbon or the Scarpa Maestrale RS, but I also have a Scarpa F1 in my wardrobe, especially for long spring tours. I mainly tested the Skorpius on a Downskis CountDown 104 L with Dynafit Radical 2.0. I've been testing the boot since Christmas and have completed almost all my ski tours with it since then. At first it was mostly settled powder, which unfortunately turned more and more into hard snow. Recently, however, there was some fresh snow again and so I was able to test the boot in real powder.

My feet are 28cm long and relatively normal in shape. Narrower ski boots tend to fit me and I don't normally have any major problems finding ski touring boots that fit. I tested the Skorpius in size 27.5, which is short in terms of length. However, after adjusting the really well-fitting liners, it fits quite well. In 28.5 it would be a bit too big for me.

Ascent

The boot naturally focuses on the ascent, which is where it really shines. It's not just the low weight and high manoeuvrability of the upper that are a big advantage here, but above all the resistance-free and fluid walking. It is precisely in this area that it stands out from other lightweight and ascent-orientated boots that I have tried so far. With the Skorpius, there really is no noticeable resistance when walking I would say that I walk more fluidly with the shoe than with some crampon-compatible mountaineering boots. However, I find it important to open the boot, or rather all the buckles and straps, completely.

The liner sits well on the foot even without lacing and, at least for me, there is no slipping and no blisters. The liner is rather on the thinner side and in cold temperatures it can get a bit chilly on the feet when standing around for long periods. However, with minimal movement, this really wasn't a problem for me.   

As mentioned, the Skorpius is very manoeuvrable to the front and rear, but quite stiff on the sides thanks to the carbon-reinforced shaft. When crossing hard snow, even with wide skis you can easily get enough pressure on the edge to prevent slipping on the ascent.

Descent

Of course, it was to be expected that the Skorpius would do well on the ascent, but things get more exciting on the descent. Especially with rather wide and long freeride skis, the lightweight should be challenged.

Overall, the boot performs really well here. In good, even snow, i.e. powder, firn or evenly hard snow, it works really well and I hardly miss my heavy freeride boots. The boot provides good control over the skis and also allows a fast skiing style. The flex is not incredibly hard, but very decent for such a light boot and above all quite even. The only thing that takes some getting used to, at least for me, is the relatively upright angle of the boot, which can only be adjusted to a limited extent.

The situation is somewhat different with more unpleasant types of snow, such as uneven crusts, heavy, damp snow or even broken harsh snow. Of course, skiing here is generally less fun, but it is precisely then that I notice the somewhat softer nature of the Skorpius. I still make good progress down the mountain, but it does get tiring. With the Skorpius, I simply have to use a lot more strength to get the ski round the corner in difficult conditions than with my Scott S1, for example.

Conclusion

The boot performs well on the descent, but with difficult snow, wide skis and tired legs, you have to realise that it is a light and ascent-oriented model. But the ascent is really good.

All in all, a boot for very ascent-orientated freeriders who are usually out and about in good snow quality. Alternatively, of course, for more ascent-orientated ski tourers who ski narrower and lighter skis.
