La Sportiva Kilo XTR Boot
The Kilo XTR draws upon La Sportiva's vast footwear prowess and is designed for those who demand more on the descent without compromising uphill efficiency. As a burlier alternative to the Kilo, the Kilo XTR brings added stiffness and support, giving ski mountaineers the confidence to tackle technical lines in variable snow. Replacing the beloved Skorpius II, the Kilo XTR utilizes next-generation materials to keep weight down without compromising durability. The Ultralon foam liner (the same foam in Intuition liners) can be molded for an individualized fit, while the WarmSole Platform provides warmth for chilly winter belays. Built for ambitious ski mountaineers, the La Sportiva Kilo XTR is the ideal boot for skiers who want a true blend of uphill and downhill performance.
- Force Flex System utilizes a Pebax RNew Tongue to ensure a stiff and progressive flex.
- Tilt-Lock Lite Ski/Walk is quick, precise, and secure.
- 68-degree range of motion offers unrestricted skin track movement.
- WarmSole Platform separates your foot from contacting the inner shell, increasing warmth on winter mountaineering missions.
- Thermomoldable Ultralon liner offers a custom fit and plenty of insulation.
- Frixion Wave Alpine outsole provides a compelling blend of grip and durability.
- Race-inspired cuff design allows for a hassle-free entry and exit experience.

Can the shell be punched?
2/18/2026
Hi Heather,
Yes, the shells can be punched. The fit is fairly wide in the midfoot, with a Scarpa-esque tight heel, and a lot of taper in the toes.

I wonder if someone could compare the Kilo and Kilo XTR?
2/8/2026
Hi Luke, they're quite similar. Essentially, the Kilo is a tongueless Kilo XTR. So it walks much better on flats, but the XTR will have a more supportive forward flex.

So I just got into touring. Twice a week I’m on my skis skinning at my local hills skiing down having fun. I don’t get to hit the resorts as often as I’d like. But when I do. I try to go medium hard. lol. Currently have the technica cochese 120 and want something more for the touring. ( I’m hooked) what’s the limitation with this boot? I’m not a pro skier..I’d say intermediate maybe a little better than that. What do you think

Hi David,
The Kilo XTR is a great middle-weight touring boot and a nice option for someone curious about trying something a little lighter that walks a fair bit better than the Cochise while still holding its own on the down. As with any lighter boot, the trade-off is that it will ski differently than the more downhill-oriented options. In this case, I would say the XTR will be softer and not quite as supportive in variable or harder pack snow. Additionally, when getting a lighter boot, it is important to make sure that it "rhymes" with the ski and is paired with something that is not too burly. The XTR would probably be ideal for a 95 mm underfoot ski.

Great. I have j skis “the flight” they are light, think they are 95mm
How these boots work well for the blues and some off the trail shenanigans
What about the sender?

If you have those skis in a longer length, the Kilo XTR could be on the light side. Otherwise, I think they'd work great for you. The Sender is a notch or two stiffer and burlier, they'd pair well with those J Skis if you have a longer length.

Unfortunately, I’m a little guy. Lol only five 165–170 pounds. Right now I’m on 167’s. Sounds like I need a heavier boot good thing I reached out to you cause I was looking to do the opposite.
I want to convince myself that lightweight touring boots can be just as effective in my downhill as they are for uphill. Looks like I need to do some more learning.

Where do I clip my ski leash to these boots?
12/23/2025
Hey Andrew,
There is no leash-specific clip on the boot, so I would clip the leash to either the cable on the lower buckle or the buckle on the cuff!

Hi,
How would you compare the fit of the La Sportiva Kilo XTR to the new Fischer Travers Carbon Pro?
Thanks!

Hi Jeff, overall they're pretty similar. The Fischer is maybe a hair wider overall. The Kilo is pretty pointed/narrower at the front of the boot, whereas the Fischer is more squared off at the toe, but gets narrower towards the heel.

How does the fit of the new La Sportiva Kilo XTR boot compare to the La Sportiva Vanguard? the 27.5 Vanguard fits me well, so am wondering about the 27.5 Kilo XTR. Thanks for any information you might have on this.

Hi Mark, they're somewhat similar overall, but different shapes. The Kilo is wider at the heel and tapers more towards the front of the boot, whereas the Vanguard has a wide forefoot but tapers towards the heel.

Hi Charles, the Kilo is a bit wider and higher volume, and the toebox is more pointed/less square.

Hi -- I'm wondering about how these fit compared with an Atomic Backland Carbon? I like my Backlands, but I'm looking for someting a bit beefier. The Backland XTD's are an option, but are said to be wider, and if anything I'd rather have something narrower.
Your thoughts on the Backland XTDs, vs. the Kilo XTRs? Mostly concerned with fit, but any other comparisons greatly appreciated.
Thanks, as always.

Hi Eric, these are overall pretty similar to the Backland Carbon. Maybe just a hair wider, and more tapered at the toe. The Backland XTD is a good bit wider as you mentioned, but still fairly low volume.

How does the downhill performance compare to the Skorpius that it replaces?
9/30/2025
Hi Ethan,
The two will ski similarly, but the Skorpius will have a slight edge in stiffness and power. From the little bit of time we had in the boot, we found that the biggest difference was in walkability. The XTR requires a little more fiddling with buckles to get the full range of motion compared to the Skorpius.

Not very psyched on this answer. Skorpius will be missed

Just landed a pair of size 26. Weigh 1200g on the kitchen scale. Getting these to replace a pair of F1 LT that are moderately packed out. Initial kitchen feelings without skiing them - they fit similar to F1 LTs (again a bit packed out) in the toes, heel, midfoot width. Fitting mechanisms (real lock bar, power straps, buckles provide a similar level of operation and control. Felt more like two variations of the same boot in fit and feel versus different boots. But, when locked down for ski mode, XTR provide a noticeable but not huge level of progressive front support - whether it's the beefier tongue or buckles and strap or whatever. Feels awesome. New to new, there would probably be less of a difference. Packed vs new is kind of not fair but it's what i have. Bottom line, i suspect for downhill oriented folks or those that don't mind a little extra weight for fitness on the way up, the XTRs will ski better. For those that need to shave grams, it's surprising how great the F1s still hold their ground years after their release.

Any insight on how these fit compared to the Skorpious 2?
7/26/2025
Hi Jesse, these fit narrower through the midfoot and forefoot, and similar in the heel and instep.

Darn. As a narrow footed owner of the Skorpius II, that means I might want to get these. ;-)
