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
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!
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 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.

I have Scarpa T1 Telemark Ski Boots - Women's (2016) shell size 5/6. Do any of the liners you have work w this boot? I think I need a 26 shell.
11/30/2024
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!

I have Scarpa T2 ECO 299mm Women's backcountry telemark boot and am looking for a replacement liner. The liner number is 250-10608-502/2. I love the boots and don't want to buy new ones.
11/25/2024
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.

Hello! I have a pair of 24.0 Scarpa F1 LT W and the liner seems a little too big (the heel is somewhat loose). Hoping to get a 23.5 liner or thicker ones. Any suggestions?
10/4/2024
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.
10/4/2024
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.

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!
Thanks!
3/21/2024
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.

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.

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.

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
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.

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

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.

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!
