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.

I need replacement liners for my F1 28 but it looks like Pro Evo Flex are out of stock. Is there any alternative? Also, since last season I started to deal with little bit of bunion on my right little finger side. Is there anything I can do to help it when I get new liners?

Filip- The Palau Tour Evo medium volume would be a good alternative as well as a 9mm Intuition tongue liner. Either one try molding the liner with some padding on your sore spot and see if that gets you enough room. If it does not then you may need to have the shell punched in that location.

is it possible (or even recommended) to replace the scrap alone liner with an alien 1.1 liner. i have the aliens in a 29 and would be interested to see if i could lighten them up a bit. maybe the paulu race liner is a better option ?
12/11/2025
Hi Ethan, looks like autocorrect didn't like SCARPA. Sounds like you're hoping to put a bikini liner in your Aliens? You definitely could, but you'd need some sort of padding for the shin. We have some that we can sell, shoot us an email at help@skimo.co. Or as you mentioned, the Palau race liner would be a much easier option.

Hi, I have the Scarpa F1 GT in a size 24. This boot is on the full size not 1/2 size. I need a replacement liner and believe its the tour LT2. Would I order that liner in a size 24 since my boot is a 24?

Hi Tracy!
You got it. The Tour LT2 is the liner for you and yes, match the liner size to the shell size. Just did one of these in the shop today!

I have a f 80 that I need a new liner for. Will you be getting any 26 or 26.5 pro flex evo in?
11/13/2025
Hi Brian,
It is possible we have some arriving mid december, but we are experiencing some tariff-related delays and cancellations.
Another liner that could work for your F1/F80 would be the Intuition Tour Tongue 9mm (Low Volume) liner here. We are awaiting a delivery on those as well, but they should be here early next week.
Lastly, The here might be another option for you that work with the F1. They are 8mm thick. These are currently in stock.

Hey there. I was wondering if the Proflex XT liner would be a good fit in a Maestrale RS (Blue ones, from around 21). Thanks!
11/5/2025
Hi Landon, the Pro Flex TK could work with the Maestrale. The thickness and everything is similar, but they do have a flex zone on top of the foot where the bellows would be, which could mess with the fit in the instep.
12/2/2025
I just purchased the Pro Flex TK liners for my Maestrale RS (white and blue model year 2022). I tested them out today and they seem to do the trick. No uncomfortable pressures or discomfort while skiing or walking around. Was very happy to find an alternative to the the original Intuition Pro Flex Tour liners that are impossible to find in a 27.5 size. Will provide an update once I get out on the skin track. Fingers crossed.

I have a scarpa f1 25/25.5 and I am looking for a liner that would give me more room at the toe box for my painful tailor bunion.
I have already punched out the boots to the max at my tailor bunion area.
Would the tour lt or alternative provide more clearance with the shell?

Jason, if you have molded the liners and worn them for some time, the foam should be pushed very thin. A thinner overall liner will not be significantly different at that little toe.

I have a pair of older F1 LTs and the liners are shot. I see the recs for the stock Scarpa liners but wondering if you might have any insights into putting one of the thicker/potentially warmer intuition liners into these boots? Is the shell volume just too small or would this work?
4/30/2025
Hi Jackson,
It all depends on how much room you have in the shell! The stock liner is the best liner if it fits you. If you have extra room and feel that the stock liner isn't taking up enough space, then you could potentially fit a thicker liner like a 9mm Intuition Tour Tongue. If you have a comfortable and snug fit with the stock liner, it would be difficult (and not very beneficial) to fit a thicker one.

Hi, I have the Scarpa Gea boot with packed out liners, and I am considering either these liners or an Intuition Wrap Liner in 12mm. Which do you recommend?
4/16/2025
Hi Emily, if you like how the stock liners fit, these are the direct replacement. Looks like we're out of the Gea replacement at the moment. The 12mm Tour Wrap will be a bit thicker than the stock liner, especially in the cuff. If you've had issues with the seams in the liner, a wrap liner might be a good option.

Alexander, The best fit would be the Pro Flex TK 29 liner. It is from the TX Pro Tele boot. Note, the T2 is a shorter boot, these liners will stick out a couple inches above the shell on your boot.

Hi Jay,
We do not currently have an ETA on getting more of the stock Pro Flex Evo liners. For a lower volume option, I'd try the Tour LT2! It is the liner for the F1 XT, which is a slightly lighter boot - it'll be a little thinner than the Pro Flex Evo in some areas, most notably in the lower shell and in the back of the cuff/behind the calf.
The closest replacement, thickness-wise, for the stock Pro Flex Evo liner would be the Intuition Tour Tongue in 9mm!

I am replacing the liners in my older women's Scarpa T1 telemark boots (lime/shark color). Is the Pro-Flex TK Women's liner a good fit? Thank you.
3/3/2025
Hi Jessica,
As the only telemark-specific liner we carry, it would be the logical choice! It is a moderate thickness - not likely any thicker than the stock liner was when it was new, but if you don't need to add more foam to the boot, it would be a good choice! The main tele-specific feature it offers is a flex zone around the bellows.

Dear skimo experts
I recently got the alien 1.0. However the reduced volume/protection of the existing liner tends to be not fully steady (the tongue move a bit on the side) and moreover some hard points in the boot hurt after a few hours of ascent, especially in traverses.
I was wondering whether another lightweight but with more volume and cushion scarpa liner that would fit, could do the job better before I start to try custom add on patches or cushioning materials.
What is your suggestion ?
Thank you very much for your consideration !
Best,
Vassilis

Hi Vassilis,
We have seen some people swapping the standard full-height Alien liner into their 1.0's in order to gain some additional support and warmth! It may require you to remove some padding from the back of the cuff depending on how large your calves are. It isn't much thicker than the 1.0 liner overall, but it does come up higher and protect more of the leg inside the boot. The Alien liners are on the thicker side for race boot liners. We would not recommend trying to put any of their normal touring liners into the Alien 1.0 - they're most likely going to be too thick.

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 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
1/23/2025
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.

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.
