Hi there!
I am looking for a liner for a pair of Atomic Backland ultimate boot shells. Similar to Dynafit DNAs. Would these be too thin? The other liners I have tried are to thick, especially around the calf.
Palau Ultralight Race Liners
The Ultralight liners from Palau are designed for skimo racing boots and other high performance applications. With an overlap design, they hug your calves while keeping the snow off your socks. The highly-rated EVA foam is thermo-moldable and adapts to your ankle movement. The Palau ultralights are designed to be compatible with Alien, Syborg, Cube, and other lightweight setups. If your race liners are beat, the French liner experts have you covered.
- 100% closed-cell EVA foam is light and thermo-moldable.
- 7mm thick version is enough to keep you warm while racing (Tour Lite Ultra).
- 5mm is thin-to-win, offering unparalleled walking capabilities (Ultra Preformance).
- Overlap design offers support and the perfect calf-fit.
- Front pull tab helps situate the liner in your boot.

Hi Hannah, I think these would be a great option. The 5mm will be a little bit on the thin side but very unlikely to be too thick in the calf. The 7mm will be maybe a hair thicker than the stock liner in the lower, and a bit thicker in the calf.

I have a pair of Dynafit TLT6 Performance boots--the green/carbon ones from maybe 2014. I'm wondering if this liner would work. (I have upgraded to other boots as well, but hoping to replace the liner and keep the TLT6s alive as a backup and for longer days).

Hi Douglas, the 7mm might work, but probably still a bit thinner in the footbox than the stock liner.

Hi! Would these work well for the old version La Sportiva Solar? I have the boot in size 28, and it has always felt tight in the toes and around the fifth metatarsal. Would these be ok either in 5mm or 7mm as replacement liners to create a bit more space in the boot?

Hey Boris,
The 5mm liner is going to be quite thin for that boot. The 7mm may work, but it depends on your foot. If you have any other questions on liners, you can reach out to us through help@skimo.co!

Would these work with the Scarpa F1 LT?

Chris- it would depend on how the original fit was for you. This liner is softer and can be a bit thinner, especially in the cuff. Look at Palau Tour Lite MV liner for a better match to the old liner.

I'm looking at getting the Ultra RS liners for a pair of Alien 3.0 boots, in size 42 (the 284 BSL). What would likely be the best size here to keep things from bunching up or being too tight? 27.5? 28?
11/19/2025
Christopher- We measured a 4.0 liner in stock in 42 and the external length was 26.5cm. I would suggest sticking with the same size, so 26.5 liner. Or at very least a 26.0 that would stretch a bit when molded.

Having quiet some Problems with the Bikini Liner of the Dynafit DNA Race Boot because it pressures right on the stitiching line on my ankle . Would you recommend the slimmer version to remove pressure or the thicker to increase cushioning on the ankle. Or is it possible to order both and see what suits best and return the other one (of course without thermo forming them).

Hi Meno,
The 5mm is closer to the stock liner in thickness. If you think you have room elsewhere to go thicker, the 7mm would definitely be an option. Shoot us an email at help@skimo.co and we can go more in depth - we'd rather help you choose the correct liner right off the bat, but happy to just ship both if that works better! Just bear in mind that they'll feel fairly different before and after molding.

Hi, I have a pair of older Alien 1.0 size 28 boots, the neon-green shell and carbon cuff version. The liners are pretty beat while the boot has been holding up with replacement parts. Will these liners work that boot in your opinion?

Hi David,
Yes, these would be a great option for an Alien liner. A coworker of mine uses them in his Aliens of the same generation. If your shell fit is pretty tight, the 5mm thickness works well - otherwise, the 7mm will do a great job filling up space and providing a bit more warmth and support.

Is there a photo/description somewhere of how the elastic strap closure system attaches to keep the top of the liner together?
1/25/2024
Hi Chris, there is actually no elastic closure system in the current model. It's now just a simple wrap style liner. They probably did in prior years, I'll update the description.

Hi :)
I have a pair of Scarpa TX, the old version with four clasps. I need a thinner lining for these, så I’m thinking 5mm. The boots are 27,5, do I order 27,5 or will 28,0 fill the boots better? :)

Hi Preben,
These might not be what you want for that boot! They are thin, probably too thin for a full four-buckle boot. They will not provide much cushioning and barely any support. They are really best used in skimo race boots, especially the 5mm version.
For a thinner than stock liner that still makes sense in your boots, you could go for a Palau Tour Lite Evo MV, or if you really want to go super thin, the LV version.

I have an Alien 1.0 27.5. Want a new liner. Should I buy the 7mm 27.5 or 28?? Do you know the thickness of the original liner? I am leaning toward the 27.5 7mm
12/18/2023
Hi Jeff! We don't suggest using a longer liner as it can create awkward wrinkles or creases which may cause discomfort. If you are looking to mimic the stock liner, the 7mm in a 27.5 would be best. Thanks!

I would like to buy a liner for my LA SPORTIVA SYBORG BOOT. My original liner size is 26.5. Which liner will fit -the 5 mm or the 7 mm one, please?
3/8/2023
Daniel,
How did the stock liner fit? Either would work, depending on how much volume you want to take up. I'd err towards the 7mm because heat molding can pack the liner, but nothing can make the liner thicker. We should hopefully have more 26.5 7mm in stock in a week or two!

hello skimo crew,
is there a chance 28.5 5mm liner will fit scarpa alien 1.0 MP28 shell? While modding(mostly cutting liner out where my big toe is) my old MP28 liner to accommodate my slightly longer foot, i found out there is enough space up front even without bootfitting, just the liner itself seems short. Thank you

Jozo,
Yes, a 28.5 would likely give you just enough room! If it is too long, it'll wrinkle at the toe though. Were your old liners the stock liner, or did you have a different aftermarket liner?

Bob, The 5mm is 'scarpa sizing' so for a 26.5 boot, get the 27. For the 7mm liner, the 26.5 would work.

Andrew, Yes, they will work and close out that draft.

Hi there!
Looking to limp another year or two out of a heavily used pair of Sportiva Syborgs with absolutely beat liners. My shells are a 28.5 and the length (toe room wise) with the stock liner is fine but definitely a performance fit, I wouldn't want it any tighter. It would be nice to take up any volume I could in the heel/calf/instep area however. Think I could go with the 7mm version and mold with a thick toe cap to get as much room as possible in the toes? Or would the 5mm version be a better bet? OR, is there another liner that would work, like one of the Scarpas? If it matters, my feet don't get too cold and most of my racing these days is longer (i.e. Power of 4, Grand Traverse, 4-5hr courses) rather than shorter. Thanks!

Anth- I think your on the right track with doing the 7mm and a thick toe cap. The only other liner is the Palau Tour Lite Pro. Its the same thickness throughout but denser foam so it might not compress quite as much as the Race Liner, but it will take up volume in the calf.
11/20/2022
Awesome, I'm going to go with the 7mm then. I can cinch the cuff down pretty tight so I'll trade a bit of extra volume there to be sure I can make room for in the toes. Appreciate it!

Hi, I have the '18 Atomic Backland Ultimate boots and want to get a warmer, more snuggly fitting liner (The boots are 25/25.5 and I typically wear a 24.5). I see in this thread that the 5mm liners have been recommended, but what about the 7mm? I have gotten the fit to feel pretty decent with insoles, but really want something more robust than those dinky orange socks.
3/12/2022
Sarah, the stock liners are around 5mm and probably more in spots. So wanting to take up more space and be warmer, you should go with the 7mm. A liner mold will take care of any spots needing more room.

Hello I’m trying to fill up some volume in a 26.5 pdg 2… would the 7mm do the trick? Also should I go 26.5 on the liner or do different a size? Thanks!
2/9/2022
Hi Jake,
The 7mm in the Palau Ultralight Race liners will not take up volume as compared with the stock liner. To take up some extra volume that is bothering you in your PDG 2s, I would recommend looking at the Palau Tour Lite Pro Evo in the 26.5. Also, achieving a snug fit can require more than just a liner change. If you have further questions, feel free to reach out to help@skimo.co!

Looking for a replacement liner for my Garmont (Scott) Excursions low cut plastic telemark boots (similar to the Scarpa T4). I don't need something super supportive, just light and flexible for long flat approaches. Thinking about the low volume version of this liner (me: high volume, wide foot). How tall is it compared to other AT liners like the Intuition Tour Pro?
2/9/2022
Hi Kevin,
All of the liners that we carry will be a lot taller than the cuff on the Excursion. The Palau Ultralight Race Liners are a lot lower volume than the stock liner in those boots. I would think you would still want more foam volume than these liners provide.
If you would like a higher volume fit than the stock liner, I would look at the Palau Tour Lite Pro Evo. For something more closely resembling the stock liner, the Intuition Pro Tour in the MV would be more appropriate.

Hi there - I am looking for a replacement liner for a Fischer Travers CS -- Wondering how you think these would do? Also wondering how warm the 7mm are compared to the tour like or other possible replacements?
2/8/2022
Hi Alex, I would suggest the Tour Lite Pro for your Fischers! These ultralight liners are a little less structured so are really intended to slip into skimo race boots. The
Palau tour lite pro evo would also work and would be slightly higher volume + warmer foam.
