Hi,
I want my Alien 1.1 fell better skinning.
I am thinking that maybe, with the 4.0 liner, and protection the shin, the experience will be better...
What do you think? Have you done this before?
Thank you
SCARPA Liners
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 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 TK - Replacement liners for TX Pro boots. Allows for the articulation needed in telemark boots.
Race 4.0 SL - Replacement liners for Alien 4.0 and related boots.
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.
Tour LT2 - Replacement liner for the F1 XT, but also very compatible with F1 LT and F1 GT boots.

Hi Jon, we haven't seen anyone do that before. Might work if you're mainly using them on groomers, but you might run into issues with snow getting in the boot otherwise. And as you mentioned, you'd need to add padding to the cuff.

Hi
I'm looking for replacement liner for my Scarpa Maestrale RS 24/25 size 265(BSL 308). After two seasons of heavy touring (and huts without boots dryers) the original ones packed out. Any recommendations?

Hi Kyunghun,
We do not have the stock liner, but an Intuition Tour Tongue liner would work well! The 12mm will be a bit thicker than the stock liner, appropriate if you would like to fill up a little space in the boot. The 9mm is closer to the stock thickness but is a little thinner.

I have an old pair of Scarpa terminators. I wondering what replacement liner you would recommend. I feel like my toes are getting chopped and hoping some new liners will help with that. Thanks in advance

Hi William,
If your old liners are worn out, I would recommend replacing them with an Intuition Tour Tongue! You would want either the 9mm or 12mm thickness. If you have a tight fit in the shell and are worried about adding too much foam, go with the 9mm - and conversely, if you have a looser fit in the shell, and feel like you need to take up volume, the 12mm will be thicker and will fill more space.
It is worth noting that a new liner will not necessarily give you more room in the toe box, and will need to be heat molded with a toe cap to open up that area and give you maximum breathing room there.

Hi Alice! Putting a larger liner in a smaller shell is generally not advisable as it will likely cause more trouble. It sounds like the boots themselves are a bit short for you. Send us an email at help@skimo.co, and we can dive into further solutions. Thanks!

The 9mm or 12mm Intuition Tour Tongue would be good options - 9 if you want to take up less space, 12 if you want to take up more space.

Hi Daniel,
After checking in with our in-house Tele expert, I would recommend an Intuition Tour Tongue in either the 9mm or 12mm thickness, depending on your fit in the shell. If you need to take up more room in the shell to prevent slop, and have more of a comfort fit, go with the 12mm. If you have a tight fit in the shell and don't want to add too much material, go 9mm.

I replaced the original liners in my Dynafit Pro Radical 25.5 with 12mm Intuition Tour Tongue liners 25.0/25.5 with excellent results, especially in downhill mode.
For long tours, I could benefit from a liner with flex zones in the tongue for better uphill performance.
Q: how does the Intuition Pro Flex Performance compare to the Tour Tongue? Thickness, tongue flex zones?
Thx

Hi Alex,
I would say the Pro Flex Performance won't necessarily walk much better than the 12mm Tour Tongue. Similar thickness as well. If you're looking to improve range of motion, you'd need either a thinner liner or a lighter, better walking boot.

Hi Megan,
We do! I would recommend an Intuition Tour Tongue liner, most likely the 12mm thickness if you would like the liner to take up some space in the shell. If you have a very tight fit in the shell, then go with the 9mm. I would recommend verifying your boot size before you order - you should be able to find the boot sole length stamped one one side of the heel of the shell. With this number and some internet sleuthing, you can determine the size of the boot!

Heidi, I have those boots too, and have tested these in there. First, all ski boot liners are taller, so these will stick up about 3" over the top of the shell.
I found the F1, or Pro Flex Evo 24.5 liner, works the best. The 24.5 and 25 shell and liners are the same.

Whoops apparently my post is also too long. Is the length/last for the 4-Pro Flex XT on the 25.0 and 25.5 liner the same?
11/8/2024
Sarah, In Scarpa sizing, the 25.5 is for the size 25.5/26 boot. It would be too big for your size 24.5/25 shell. You would need to do a good liner mold to get that custom fit.

Hi Catherine! Scarpa boots break on the half size, so the 23.5 and 24 shells will be the same. Send us an email at help@skimo.co and we can dive into the details of potentially finding you a better fit.

Catherine, I feel the F1 LT liner is very good and hard to duplicate with a replacement liner. And there isn't a 23.5 liner.
Since you are trying to change just the heel pocket, I would suggest trying this instead - liner sleeve

Question from
Robert 
I'm still rockin' the Scarpa Freedom SL's. I've had these boots for about 10 years and the shells are still in really good shape. I replaced the original liner about 5 years ago, which was very effective in making the boot feel like new again. The liners are pretty packed out and now I'm curious about other liners to consider for getting that increased comfort again. I have a relatively low profile foot and thinner calves/ankles so I definitely would like the new liner to be filling in the space rather than trying to constantly tighten the buckles down in order to make it snug when skiing. Is there a recommendation on a liner that is a little 'beefier' that could work?
4/23/2024
Hi Robert,
I used to have a pair of those, so I'm familiar with the stock liner. I'd go with an Intuition Tour Tongue or Pro Tour in the 12mm (medium) thickness. It'll be a little bit thicker in the body of the liner than the stock, but not too much, and it's the same excellent, moldable Intuition foam.

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
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.

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.

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?

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.
