Racing and touring is hard on liners. Sweat builds up; articulation causes chafing. Replace your SCARPA boot liners with a fresh pair, listed below by model.

4-Pro Flex XT - The Intuition liner for the 4 Quattro XT and 4 Quattro XT Women's boots.

Alien - Updated Intuition liner that comes with the newer Alien boots (since 2019/20). Also known as the Cross Fit Tour Lite liner.

Alien 0.0 (original) - The original Intuition liner designed specifically for the 0.0 version. Fully heat moldable and has a tongue for easy entry. Velcro closure at the top keeps it tight.

Alien 1.0 (original) - Intuition Light liner is as snug as a sock. In fact, you have to put it on before putting on the shell. Moldable, but thin so you won’t get too much extra room.

Alien 1.1 - Intuition Crossfit BT Liner for the 2nd version of the Alien 1.0 that we all refer to as the "1.1" edition here at Skimo Co. Big tongue but nothing in the back.

Pro Flex Evo - Replacement liner for your F1 boots. Also a great liner for other boots if you want a thinner Intuition liner (as compared to the Pro Tour). Women's version also available for your F1 women's boot!

Pro Flex Performance - Wonderfully warm and massively moldable, this is the replacement liner for the Maestrale RS 2.0 and 3.0 boot, blue highlights and all. Women's version is for the Gea RS 2.0.

Tour LT - And also Tour LT Women. These are the liners found in the SCARPA F1 LT and F1 LT Women's boots. Typical Intuition foam that also works great in other boots.

Question from Mike K
 
I have some Scarpa F1s (not LT). They are 28 shell, currently with a 27.5 liner. I want to size up to a 28 liner for a Denali ski trip. Can you recommend a liner for this purpose? Thanks
4/12/2024
Answer from Emmett I
 
Mike,
The Scarpa 27.5 and 28 liners are all the same. There is no more volume in a 28, and they actually only sell the full size liners. A thicker liner will also change the fit, obviously. Having a tighter fitting boot can restrict circulation, making for cold feet.
Many people will get a boot a size bigger, then add a thicker Intuition liner.

Answer from Carlos M
 
Hi Mike,

Scarpa boots break on the half size, so the 27.5 and 28 shells are exactly the same. We only stock whole sizes in the Scarpa-specific F1 liner. For additional warmth, we often recommend Intuition liners due to their warmer foam. Scarpa liners are of course made by Intuition, so the next step would be a thicker one (assuming you have room in the shell to accommodate it).

The  Intuition Tour Tongue in the 9mm volume will be slightly thicker in places than the stock F1 liner, and will work well with the normal fit of the boot. If your shell is a bit bigger on you, and you have extra room, you may be able to get a 12mm Tour Tongue in there, which would provide more insulation. However, if it's too tight a fit, it will squeeze your foot too much and ultimately be colder.

I would size either Tour Tongue thickness at a 28, which should give you slightly more liner compared to a standard Scarpa 28. You will want to heat mold these for room around the toes, especially in a colder climate.

Question from Ester
 
Hi, my ski boots (Scarpa Freedom SL Wmn, model year 2015 or 2016) are still pretty fine, but the liners need to be replaced.
My liner size currently is 255, original liners are Intuition FR Speed (see photo). Ideally the liners are replaced with a similair pair, as they fit my feet very well. Do you have any advice on which liner to choose?
3/26/2024
Answer from Jeff
 
Ester, You would want the Maestrale/Gea liner, but we do not have any. They are made by Intuition, and you can get those, in size 26 MV. The Scarpa 25.5 and 26 are the same and you would use the 26.

Question from Spela
 
Hi, I need a replacement for my Scarpa GEA RS Liners. Which liners from Intuition would be most comparable to the existing (Cross fit Pro Flex)? I suppose this could be Tour tongue 12 mm - the question is the density - dual, high, low?
Thanks!
3/21/2024
Answer from Emmett I
 
Hi Spela,

The Tour Tongues will be the most comparable aftermarket Intuition liners. The Tour Tongue is only available in dual density. They also have Downhill Tongue liners available in different density options, but we don't stock those. The 12mm Tour Tongue will be a little bit thicker than the stock Gea liners, which is often what folks are looking for in an aftermarket liner - it fills space a little better and will mold nicely. The 9mm is a great option if you were happy with the fit of the stock liner and aren't really looking to take up any more space/if you had a tighter fit.

Question from Ray
 
Hi,

I'm looking for a replacement liner for the stock liner that came with my size 26.5 Scarpa Maestrales from 2019-20. How do you recommend I deal with the 1/2 size? A local shop suggested getting the 27 and going a bit thicker than I otherwise would. Any recommendations in terms of model and size. Just looking to replace what I have.

Thank you.
3/5/2024
Answer from Emmett I
 
Ray,

I would go with a 27 over a 26 if you have a 26.5. I wouldn't recommend going thicker necessarily. We don't have any of the stock replacement liners left aside from a 31, but a medium volume Intuition Tour Tongue would be a good option.

Question from Scott
 
Hello,

Which liners would work best for my Maestrale XT’s?

Thanks,

Scott
2/24/2024
Answer from Carlos M
 
Hi Scott,

Since we do not have the Maestrale RS liner in stock at the moment, I would look at the  Intuition Tour Tongue liners. The 12mm thickness (medium) is likely the best, unless you have either a very tight or very loose fit in your shells.

Hi, I would like to remove volume from my F1GT which is too wide in size 30 and I was thinking of using this liner in size 29, is it possible? make it sense?

Answer from Emmett I
 
Mat,

Sizing down your liner won't take up more volume. You'd need a thicker liner - shoot us an email at help@skimo.co and we can get you some recommendations!

Question from brian
 
I notice the F1 and F1LT use different liners. Assuming its probably not kosher to put a 29 F1 Pro Flex Evo in a 28.5 F1LT shell? Any insight is appreciated.
2/6/2024
Answer from Carlos M
 
Hi Brian,

They do use different liners. The F1 LT is a significantly lighter and lower-volume boot than the F1, so the liner is thinner and shaped differently. Putting a Pro Fex Evo into an F1 LT would make the fit considerably tighter and might restrict the walk mode a bit. Not necessarily recommended for most people. That said, 28.5 and 29 are the same shell in Scarpa, so the sizing would work.

1/9/2024
Answer from Niko M
 
Hi Michael! You bet! The Flex XT will fit into the SL shell well with no troubles. They are likely very similar, however with careful attention to detail you may find the XT to be a touch stiffer. Thanks!

Question from Justin
 
Whats the thickness of the Alien liner? Are they the same as the liners that came in the prior generation Aliens (the ones with the yellow cuffs)? I have too much room in the ankle and heel of my Aliens, I've tried the Patriot liner sleeve and it doesn't really do the trick. What would be a suitable replacement liner that would take up a bit more volume but not reduce the range of motion much? If it took up a little volume in the cuff too that would be OK
1/4/2024
Answer from Carlos M
 
Hi Justin,

They are not the same liner, and are pretty thick for a race boot liner. They are high quality Intuition foam and will mold well. I would say they are likely to provide a better fit than your original liners, once molded. Another option that might be slightly thicker is the  Palau Tour Lite Evo MV . These are very comfy and hold the foot in well.

Question from James Carter
 
Hello
I just got a pair of the Maestrale Rs 2022/2023.
I have a very hard time fitting the liner back into the boot.
Any savvy tricks?
Thanks
12/7/2023
Answer from Niko M
 
Hi James! Sorry to hear about the struggles! No savvy tricks here, but what I like to do is to start by tilting the liner forward and working the toe as far forward in the boot without having to apply to much force. I then grab the gaiter near the back of the boot and drive the heel of the liner in using my fist. This will force the toe forward and set the heel in place. Hope this works! Thanks!

Hi Taylor! The Pro Flex Performance liner would take up too much volume in F1 LT. For what you are looking to do, I'd suggest checking out the Palau Tour Lite Pro Evo Liners

I want to replace the liner in my S/lab MTN Summit boots with an intuition/Scarpa liner. Which of these liners would be best?
4/17/2023
Answer from Jeff
 
Daniel, For the Summit boot, the Pro Flex Evo (F1) liner would probably be best if you want to take up more space. If you want a liner a bit closer to the stock liner, the Tour LT would be it. Note Scarpa shell and liner sizing is different. Check with help@skimo.co for more assistance.

Thx

Answer from eric
 
Mark- The Pro flex evo liner would be a little thin in the foot. The Pro Flex performance would be a better choice or just going to a straight Intuition liner.

Looking for new liners for my Scarpa F1s (2018/2019 version). I want the Proflex Evo in size 27.5/28.0, but I haven’t seen them in stock for a while. Are there any other liners I could consider. I tried Palau Power LTs and they have too much volume.
4/6/2023
Answer from Jeff
 
Hi Dustin,
Sorry, getting Scarpa liners is tough. The Power LT would be good, if your boots were a bit big. The next one down would be the Pro Lite. They are thinner at the foot, and cuff.

Hi there - your advice looks very good! I have a pair of Scarpa Maestrale (not sure which version), and I need new liners.

I can see earlier advice being that the pro flex performance would be best however the tour LT look more alike to the liner currently in the boot.

Would be really appreciative of any advice. Thanks, Charlie
3/30/2023
Answer from Emmett I
 
Charlie,

The Pro Flex Performance will be the closest to the stock liner! You could also possibly try an Intuition Pro Tour, Medium Volume. The Tour LT is much thinner.
