Atomic Mimic Liners

[onenerdykid]

For about the last 5 years, Atomic has been working hard at figuring out how to make liners more comfortable, have a longer lasting fit, and be more customizable so you can have the exact fit you need. For the 20/21 season, we are introducing a new customization technology called Mimic.



Mimic liners offer the same exact first fit as our current 3D liners but with the added benefit of complete customization in the ankle/heel area, tongue and calf. Not only is this customization complete, but it is done in a matter of minutes with the existing Memory Fit oven, is repeatable and mess free.

Normal “3D“ liners only mold to the ankle/leg due to the heat-moldable EVA foams used in their construction- the actual 3D shape does not change. Having a liner that fully molds around the ankle/leg has been traditionally found in foam injection liners (liners where foam is pumped into the liner). While this is 100% custom, these liners are very expensive, often associated with a high risk of mistakes being made, and can be messy. Mimic liners offer the best of both worlds: complete customization that is done in an easy and repeatable way without any mess.

Mimic technology is not a foam, but instead a special material that softens when heated and fully hardens when cooled. This means that when it forms to your ankle area, your shin, your instep, and your calf, you get a shape that is 100% yours and it stays that way. There still are heat-moldable foams in Mimic liners, just like our normal 3D liners have, but Mimic is the proverbial magic that ensures your fit happens the way it should.

To demonstrate just how moldable the Mimic material is, I would often show a Mimic prototype that had its ankle area squished and my fingertips would be imprinted in the liner itself (you can see this in the below picture).



I would also flare out a tongue to show that not only will it wrap around a skinny leg but also fit a larger leg (upper picture with red tongue is the standard shape, lower picture shows a widened tongue)



Ultimately, Mimic liners will ensure that you have your fit comfortably captured in the liner and hardened in place. This means you can have a comfortable fit that performs at its best.

For the 20/21 season, Mimic liners will be found in men’s & women’s Hawx Ultra, Hawx Ultra XTD, Hawx Prime and Hawx Prime XTD boots. The liners will also be available separately if you already have one of those boots and just want to upgrade the liner.

If you want to hear more about Mimic liners, check out the podcast I did with Jonathan Ellsworth over at Blister Gear Review: https://blisterreview.com/podcasts/a-very-deep-dive-on-ski-boots-part-4-liners-ramp-angle-forward-lean-ep-88#comment-434282

And as always, feel free to drop any questions below and I will do my best to answer them for you.

Pretty cool buddy.

I was looking at these loads over the last month trying to figure out exactly what you guys had done, so thanks for the intel

Looking forward to trying them out.

 

[n3vrast]

First of all, great podcast with you and Jonathan.

Second: I did not quite catch if the XTD-liner is exactly the same liner as the 130s (alpine boot) but with a flex zone in the back, or if it is a lighter version. As mentioned in the XTD-thread, I am in the category of low volume LOW instep, and had to sell my XTD130 and replase them with XTD120 (with 2 layers of those white sole-spacers) due to lack of fit in the instep area after #memory-fitting" the shell+liner.

I'm happy with the 120, but it is lacking a bit in the stability section on piste (I`m 90kg), would you recomending buying a new liner, or just the the next years 130s with the new liner. And If I do, should I memory fit (cook) the liner or will it compress the tounge/instep area in the process? (I know you mentioned your chicken legs etc etc, but not sure if you ment the area around the shin or the instep itself ).

Cheers

Thanks! The 20/21 Hawx Ultra XTD 130 will come with a Mimic Platinum liner, which is the same as the normal Ultra 130 Mimic Platinum liner but with a flex zone for touring/hiking. Think of your current 120 liner, but next level.

You can always ski the liner out of the box and see how that suits you first. If you feel like you want a more uniform fit, then you can always go through the Mimic liner fitting process.

 

[tomPietrowski]

Yeah Steve would not tell me much so figured we would be taking a knife to them haha.

Good to hear, but is the plastic in the in step area also a part of the "magic" in the new liners? I want to cook the liners but I am afraid it will increase the volume in the instep. But if the tounge is changed in the mimic liner maybe it will retain the volume better than the orange 130-liner did a couple of years back?

The out of the box volume will be the same as your 120, so much thicker than the original, orange 130 liner. So, yes, it will definitely fit tighter than the original 130.

What Mimic won't do is make a fit tighter- we're not adding any material into the liner, we're just reshaping it to your foot/leg and hardening it place. It's optimizing the existing fit, not reducing it. The only liner that will create a tighter fit will be a foam injection liner.

 

[elm.]

How is this different or better than an intuition liner?

 

[NvR_Forgetti]

Obviously you don't want give away all your secrets but what is the material that allows it to be remolded? is it similar to Zip Fits Cork material? or something different?

Also how many times can you re-cook the liner?

 

[TheWeaz]

Is the mimic heat molding done along with the shell memory fit? Without something like the fisher vacuum wouldn’t this only allow the boot and liner to accommodate legs and feet that are bigger than the stock configuration and not allow a smaller ankle pocket to be created.

 

[onenerdykid]

How is this different or better than an intuition liner?

Intuition liners are EVA foam. No plastic elements, moldable plastic elements or other materials.

An Intuition liner will be lighter, but it won't hold it's shape the way Mimic will and it can't provide the same level of power transfer or skiing responsiveness that a Mimic liner will.

 

[onenerdykid]

Obviously you don't want give away all your secrets but what is the material that allows it to be remolded? is it similar to Zip Fits Cork material? or something different?

Also how many times can you re-cook the liner?

The OMF cork material in a Zip Fit liner is more fluid than solid. Because it's a fluid, it constantly moves. We used to make our race liners this way about 10 years ago and the biggest complaint was that the fit changes when you don't use the boots (again it's a fluid that settles and moves). Our Mimic material is solid- it doesn't compress, it just changes shape when warmed and it fully hardens when cooled. The only thing that will change over time are the heat-moldable foams that are next to skin.

We've heated, molded, re-heated, re-molded a liner over 15 times and the Mimic material still does its job. But, we say that the liner can be re-cooked about 4-6 times because eventually you will break down the other components in the liner before the Mimic material does. In the hands of normal boot-fitter, you do it once and you're good to go. But if something changes in you (like you break your ankle over the summer or something) you can totally re-mold the liner again and reshape it to your needs.

 

[onenerdykid]

Depends on what you need.

If you need the shell expanded, then Memory Fit + Mimic is an option.

If you are like me and don't need the shell expanded, just doing the Mimic liner is awesome.

Just think of the molding process for an Intuition liner and if you know how well that works, this will work even better.

Just coming back to this point, I'm currently riding a Hawx XTD 115 as I have stupidly small feet and narrow calves and ankles, I always end up having to over tighten boots to get my heel to stay put, would the mimic liner be able to help in this situation or do I need to go down the foam injection route.

I go to a very good boot fitter (Colin Martin at Solutions4Feet in the UK) so it's not a case of a poor fitting in the first place.

Thanks Matt!

Colin is awesome, we worked with him in dialing in some of our Mimic prototypes over the last year.

Compared to your current Ultra XTD 115 which has a more touring-oriented liner, the Mimic liners will be more substantial for sure. To get a feel for what it would be like, you can always try on a normal Hawx Ultra 115 in your size and that's what it will be like.

 

[olic]

Thanks for answering Matt, I've sent Colin a note as well seeing as he and Kieth fitted the boots to see what he thinks. I've always struggled with heel hold so this could be the right way for me to go, either that or Zip Fit. Will see if I can find a Hawx Ultra to try on and see how I get on.

Great podcast with Blister again by the way!

 

[profa_212]

Man these look pretty sick. Need to replace my og xtd liners (orange) and was gunna go with intuitions but I will probably get these now.

I rock the regular Ultras inbounds ....would these liners fit more similar to the current platinum liner?

They will fit exactly similar, 1:1, with the added benefit of the Mimic tech, so it will feel way more uniform around your foot and stay that way.

Awesome! That's exactly what I want!

 

[cydwhit]

Stoked to see this happen, especially since my weird fit issues do not stop at my ankles, stoked to lock everything in.

Can't wait till they're available separately, probably gonna have to snag a pair!

Ethylene vinyl acetate is certainly a plastic.

So your magic foam is just denser and stiffer?

 

[onenerdykid]

Ethylene vinyl acetate is certainly a plastic.

So your magic foam is just denser and stiffer?

Sure, but when you hold a sheet of PU plastic in your hand and a piece of blown PU foam in your other hand, you don't think the two are the exact same thing. One is a hard plastic and one is a spongy foam. Both are PU but they have completely different properties.

You'll have to forgive me for not spilling the beans entirely (this is a public forum after all ), but what we are calling "Mimic" is not a foam nor would it ever be mistaken for a foam.

 

[Topsen]

Sounds really interesting!

How would you say is the warmth in those? I understand its not foam, so hopefully not as freaking cold as foam liners...

Also, will they be available separately?

Cheers!

Warmth will be on par with our existing alpine (not touring) Platinum liners, which is to say rather good (we use various closed-cell EVA foams around the entire foot so there is really good heat retention at work)

Intuition is probably going to be warmer still since their liners are so thick which means their insulation properties will be a bit higher.

For what it's worth- I'm a total bitch about being cold and my toes have always frozen in boots since forever. But in the last 2-3 years since using these liners (and being in a 1cm shell fit) I haven't had any warmth issues. It's been kind of surprising to be honest.

Liners will be available separately in the following fits: Hawx Ultra, Hawx Ultra XTD, Hawx Prime and Hawx Prime XTD, for both men & women, with a complete size run that corresponds to each family.

 

[TheWeaz]

Sounds to me like mimic is basically just a thermo plastic? Similar to kydex, although I assume it has different properties that are desirable for ski boots. But basically the mimic material itself it close to infinitely remold able as long as you don’t go over the materials melting point, is this correct?

Compared to the current hawx xtd grey liner, is the new xtd mimic liner going to take up more room around the ankle? Would there be a better way to mold the liner or shell to decrease ankle pocket size or at least increase the hold the ankle pocket has on the foot to create a sculpted liner similar to what Nordica has going on with the cork ankle pocket on the pro machine.

Asking as someone who obviously has too much room around my ankle in the hawx xtd.

If you try on a normal Ultra 130 (non-XTD), that's exactly how the liner will feel. For sure tighter than the current grey Ultra XTD 130, exactly like a normal Ultra 130.

This will mold far better than what Nordica is using in the Promachine. No hate towards Nordica- I legit think they make great stuff, but you can't really compare the two liners.

I wasn’t comparing the two in terms of mold ability, just the fact that the stock liner from the promachine has a much more defined ankle pocket than any boot I’ve seen right out of the box. my question more was what method would a boot fitter or shop take to get a mimic liner to have a shape similar to that, assuming we have access to standard boot fitting tools and the amer sports memory fit shell cooker.

 

[onenerdykid]

my question more was what method would a boot fitter or shop take to get a mimic liner to have a shape similar to that, assuming we have access to standard boot fitting tools and the amer sports memory fit shell cooker.

There are 3 new tools that shops need to have (toe cap set, over-the-liner sock, and a big shoe horn) in addition to the normal Memory Fit Oven.

Your Atomic sales rep will give you access to the "How To" videos we made for the Mimic fitting process. Basically, if you can do Memory Fit, this is 2 additional steps. Super easy.

 

[GardenPatchy]

How much will the liners cost?

 

[aanev]

I bought 3D Liners for my XTD130s a couple of weeks ago from Atomic. I also have Intuition Tour-Wrap molded for them but discovered gradually that I prefer the feel, the shock absorbtion and the progressive flex of the3D Gold liner (XTD120) so I ordered a pair. The original XTD130 liner does not work for my feet.

The question is:

Will I have any benefit should I decide to upgrade to the Mimic liner given that I do not have hot spots (even without baking) in the 3D liner and after 10-15 days of use – once broken in - it fits even better.

Could you please share your thoughts?

My current situation is following:

I have Hawx Ultra XTD 130 with WTR soles. Bootfitter suggest me to use Intuition Tour Wrap, because original orange liner didn't create a secure hold for my heel.

I like Intuition for backcountry, but want something more plush for resort. Will Mimic liner fill that purpose? Which exact liner should I look for to use it on resort days with mostly lift accessed skiing and some short touring laps from lift line?

Also, do you know liner's price for Europe?

The new Mimic liner will fit you more uniformly, period. The heel, ankle, instep, shin, and calf of the liner will shape exactly to your body. It's definitely a step up from the 3D Gold liner (which is still nice for sure).

The Mimic liner will do exactly that for you and I will bet dollars to donuts that you don't even touch your Intuition liner once you get the Mimic liner.

Pricing will vary a little from market to market, but you're looking around 200€

Thanx man

Should I ask for Atomic Ultra XTD Platinum Mimic liner in my local shop? (that's some really long naming scheme xD) I think I need to preorder them, cause usually it's really hard to get it in 24/24.5 size.

Yeah, a little long of name but it's the only way to make sure you don't order the wrong one.

I sent the part number to you via PM

 

[frank9190]

I was surprised to see no more hole to be able to lace up the liner. Can you explain why you chose to get rid of it.

 

[Abcdethan]

How much weight does the new mimic liner add to next year's Hawx Ultra XTD boot? I was going to order this year's model after demoing the boot, but they sold out. However, they are working on getting the 20/21 version for me in my size.

I posted this in another thread, but I think it's like a 130g increase. The boot is still one of the lightest in its category.

 

[Abcdethan]

Thanks for the answer. I found the thread. One more thing. Atomic was going to send me one of the new boots. Can an existing shop mold this liner now, or will I have to wait until the fall for them to get the equipment for the two other steps of molding that you mentioned?

They will need to have a few specific tools, which we provide but shops can use substitutes from other companies if they have them. The shop should get in touch with the local sales rep to get the "how-to" video we made for molding the liners and see if they have the needed things.

 

[jca]

[tag=134699]@onenerdykid[/tag] what do you think about putting these into different shells as an aftermarket liner? Still looking for an inbounds/touring goldilocks for my Lupos.

Definitely plausible. Mimic liners will mold to the shell and to the foot, so as long as it's a good start, then it would be a great option.

All products are going to be in short supply this year due to the problems Covid is causing. They do exist and dealers brought them in, but not a lot (one of the problems of Covid is that retailers aren't buying lots of stuff this year). Keep calling places, they are out there though.

Now all we need are liners that don't pack out...

Wow - that is a super goof haha. Jump on that price before it gets changed.

There aren't any DIY instructions unfortunately because of the tools that are required. I know it's tough in your area but if things can come back to normal this winter, I can help you out on your next ski trip. Let's hope for the best!

Thank you! That would be great!

Let's hope that life goes back to normal and storm-chasing is still on the menu ! Would totally enjoy another day skiing in your fine company, sir!

Is this liner best heated on a heat stack or in an oven? If the oven what temp and duration is reccomended?

 

[onenerdykid]

Is this liner best heated on a heat stack or in an oven? If the oven what temp and duration is reccomended?

A heat stack on its own won't work. You will need an Atomic/Salomon Memory Fit Oven, a special shoe horn, socks for the liner, and toe caps. Speak to your local Atomic rep for the "How To" video so you can check out the process because it's very important to do the steps how we say and when we say.

 

[NvR_Forgetti]

Does the material expand to mold around the foot like the intuition liners? And if it is does it re-expand with each heat or just make it malleable to adjust the fit of the liner?
