La Sportiva Kilo Boot
As many are figuring out, light and skiable is a winning combination. With the Kilo, La Sportiva has created a boot for the ski mountaineer who desires to access far-out lines while still having enough boot to confidently navigate through whatever conditions present themselves. Being constructed entirely of Grilamid Bio-Based LF Carbon, a light and rigid material, the Kilo has a relatively stiff flex that punches above its weight. To help fend off cold feet, La Sportiva devised their WarmSole Platform, helping insulate feet from the cold rigid shell. The Force Power Buckle and Closure System allow the boot to be securely and evenly snugged across the foot, allowing for a comfortable and precise fit. Finally, the Tilt-Lock Lite ski/walk mechanism is reliable and user-friendly, even with bulky gloves. With its athletic weight and stout demeanor, the Kilo is a worthy companion for those who want to venture far from the beaten path.
- Force Power Buckle allows the boot to be snugged securely against the shin, helping prevent shin-bang.
- 70° degree range of motion allows you to move quickly and efficiently.
- Force Closure System allows for a precise and even fit across the foot.
- Stretch gaiter keeps out snow to help your feet stay warm and dry.
- WarmSole Insert insulates against the cold shell.
- S4 Binding inserts allow for easy entry into Ski Trab bindings.
- Tilt-Lock Lite ski/walk mechanism is easy to use, even with bulky gloves.
- FriXion Wave Alpine sole combines harder and softer rubber compounds to provide reliable traction without premature wear.
- Forward lean options of 12° and 14° allow you to dial in your stance to your preference.
- Grilamid Bio-Based LF Carbon was developed specifically for La Sportiva, allowing for a rigid platform at minimal weight.

Am I reading correctly that these are only 80g lighter than the Skorpius? I love Sportiva, but to call a 1.12kg boot the “Kilo” is pretty disappointing marketing. I really wanted a true 1000g boot with 2 actual buckles to round out my quiver. Looks like I’ll have to keep waiting.

Hi Greg, in fairness to the Italian marketing team, most boot makers now use size 26 as their reference whereas we use size 27 for historical consistency. I was also expecting a bigger difference from the Skorpius, however.
Answer this question:
Wanted to post a quick review for those looking at this new boot. Just have one tour on them, so take that into account. I am coming from the Fischer Traverse CS. Overall I think they feel beefier/stiffer than the Traverse and ski a little better, at least on a 85 wasted ski, in very variable conditions. Definitely a noticeable difference. Closer to Fischer Trans Alp Pro in my opinion. But I am comparing a brand new boot to one with a couple seasons of heavy use. Fit is similar to what has been mentioned by the SkiMoCo folks. I have a very narrow foot (B width) and high instep. Size 14/48 for most running shoes and went with the 29.5 size - toes touch the end but are not jammed. I would say the width at the forefoot area is average, maybe similar to Traverse. Not as narrow as I would prefer, but manageable. The toe box is fine for my foot. The instep is roomy enough for me. The heel is narrow and feels pretty locked in. I will update my review as I get a few more tours in them. One boot in the 29.5 size weighs 1266g. My 29.5 Traverse with Palau tour-lite liner (with holes in it), weights 1235g.

Would you say that the Skorpius ii and Kilo are in two completely different classes when it comes to downhill performance?
Also, do we know the BSL for these in 27.5? Are we expecting 297?

Hi Olivier,
Yes, I would say the Skorpius and Kilo are in two different classes of downhill performance. The Skorpius is very stiff and supportive, it punches above its weight and is one of the best in the general touring category for stiffness and flex. The Kilo, while it does ski well for its weight, is a much lighter race-plus boot with a tongueless design. It can't quite hang with the Skorpius on the downhill.
No BSLs yet, unfortunately, but we will get those numbers up when the boots come in!

Seems like the kilo didn’t end up as light as originally hoped or advertised. Is that correct that it’s only 75g lighter than the skorpius? If so, setting fit aside, does the 75g difference justify the trade off in downhill performance?

I really like that this went back to a buckle over boa, especially the ankle buckle! The fit of a mastrale with the ankle hold is unmatched IMO, so im stoked to see this in such a light boot.
Initally, how does this feel compared to a scorpious CR ii? or an F1? Looking for a new boot to drive a DPS RP 100 and this may be on the lighter end but could fit the bill

Hi Scott,
From what myself and my coworkers can recall from our limited time demo-ing this boot, the fit is relatively similar to the Skorpius - lower volume, and narrow in the heel and midfoot, but with a more generous width up front than a Scarpa F1 LT. It is narrower and snugger than the F1. The toe box does taper in the front, so perhaps not the best for someone who typically needs sixth toe work.
Our consensus is that the Kilo is not quite enough boot for the Pagoda 100 in sub-optimal conditions. It would work in powder and might be desirable there, but it is a pretty light boot and best paired with a lightweight ski up to around 90-95mm. That said, people do push boots in this category harder - you'll just notice the limitations in more adverse conditions.

How would you compare the fit of the Kilo side by side with the Skorpius? Based on what you wrote it sounds like the Kilo is notably narrower in the toe box vs. the Skorpius which is relatively generous there. Is that correct?

Hi Ben,
I think the Kilo's toe box is more tapered at the front in the pinky toe area, it cuts in more than the Skorpius. But the width at the ball of the foot, from what I can recall, was similarly generous. I do want to qualify this by saying that it has been some time since I tried this boot on and I wasn't in it for long, so this isn't conclusive!

Stoked about the arrival of this boot! How wide/narrow is this boot compared to the F1 LT?

Hi Taylor,
When I tried it on, my thoughts were that it was a little wider than the F1 LT at the ball of the foot through the midfoot, but the toe box tapers in towards the big toe, right at the front. It does have a snug heel pocket, on the narrower side there. It should be a sweet boot, early feedback has been that it skis very well for a boot of this weight!

That’s great to hear! I need a little more width in the ball of the foot and less volume in the heel than the F1 LT. High hopes for this one! I’m curious about the toe box volume and how that’ll feel. I imagine because it’s a carbon grilamid boot any punching is ill-advised and warranty-voiding? Any idea when the boots will be hitting the shop?
8/14/2024
Hi Taylor, sounds like these won't be landing until late October. There is going to be a limit on how much you can punch that material, but minor changes should still be possible.
8/14/2024
Thanks for the update jbo! I’ll stay patient until then. Looking forward to their arrival!
