How to Heat Mold Your Ski Boot Liners & Shells at Home. Get that custom fit in your own kitchen!

[@geirheggertveit]

It is very important to mention that the temperature is mentioned in Fahrenheit, not Celsius. 😉🤞(220F is 104 degrees Celsius) This method is very good, and I have used it since the early 90s. 👌

[@amundsen84]

@geirheggertveit 104 grader i 17 minutter blir den norske oppskriften altså?

[@Jaychmpn]

Work perfectly for my K2 b&e 2024, except I left my pro wrap Intuition liner inside. A huge thanks! I will reproduce it in the future 👍🏻

[@Dangerpass]

I followed his advice except I left the liners in. The results were perfect! My full-tilt boots fit like a glove!! Many thanks Mountain man for this sage advice!!

Awesome, get out there and RIP IT UP!!!

I did this with a pair of Lange RS (blue) boots and liners as well as Lange XT3. I had fractured my 5th metatarsal and the outside of my foot is quite wide and causes problems. I put the liners in for the final 10 mins of the prescribed 17. So shells got 17 mins, liners got 10 mins at 220F convection. My foot was quite hot in the RS liner. More so than the XT3. In both I stood outside in the cold for 20 mins in the boots to let them cool to shape on my foot while leaning into the boots in a ski position. WORKED GREAT. Boots are literally form fitted now to my ankles and feet. Will be doing this again for future boots.

[@craigpiefer7839]

AWESOME! Now go out there and RIP!!!

[@philwistrom9200]

I just got a new pair of Lange XT3’s and want to do this. Are both the liner and shell supposed to be thermo moldable??

[@sgcole111]

I heat molded my Nordica Promachine at home. My approach is similar, slightly different and delivers excellent results. (1) Oven temp is 200F. (2) Heat soak is only 5 minutes. (3) After 5 minutes of fitting, I step into icewater bath with boots (make icewater bath in large Coleman cooler) for 5 minutes. (4) towel dry. Cautionary note: The time required to heat ski boots in an oven depends on the brand and the type of shell being molded. For example, Salomon's custom shell takes 10 minutes at 100°C, while their HD shell takes 2 minutes. Atomic's memory fit shell takes 5 minutes at 117°C. In general, you can expect to heat ski boots for 5-8 minutes at 220°F. You can use a laser thermometer to check that the plastic has reached a temperature of around 80-90°C. Convection oven HIGHLY RECOMMENDED.

[@kellyburgessart]

ugh thank you so much. if I had tried this before so much pain could have been avoided and so so much money saved.

[@foch3676]

Thanks for great video. And My Gas oven cannot use convection with 220, Is it possible without convection?

[@bigwave_dave8468]

It's useful to have an in-oven thermometer as convection ovens don't necessarily show the true temperature (they may be calibrated to cook foods similarly to non-convection). Also, you can use a nylon stocking to hold the extra toe sock or cup in place.

[@RipleyShakespeare]

So glad I found this video big up mate very informative!!

[@MichaelODonnell-Gmail]

Did you leave the footbeds in your boots when heating them in the oven?

[@mainstreamMTNguy]

NO! Great question, take them out. But if you leave them in, it's not the end of the world either.

[@MichaelODonnell-Gmail]

@@mainstreamMTNguy thanks! I’ll let you know how it goes..probably better than surefoot did 10 years ago!

[@mikehoffman7131]

great video. I have some full tilts on the way to me (United Kingdom to Pennsylvania) once they finally arrive, I will be doing this.

[@mainstreamMTNguy]

Sounds good, enjoy that comfy fit!

[@mikehoffman7131]

@@mainstreamMTNguy and you did say 17 minutes at 220 right? Ive always done like 8-9 minutes at 200. all for trying something new if it is a proven method for someone else. have you done this with intuition liners as well?

[@mainstreamMTNguy]

@@mikehoffman7131 Yup 17 minutes at 220. And yes I have used this method on Intuition Liners; worked great!

[@mikehoffman7131]

@@mainstreamMTNguy the molding process worked great. The boots feel wonderful. The ratcheting booster strap melted and broke but that can be replaced

[@rourkebrummette3294]

Just put the boots and liners on a baking sheet. Liners started melting after a few minutes. Not sure if he uses some sort of paper or not but they melted on the baking sheet slightly. Luckily they’re used and I caught it before it got bad. I also did not have a convection oven

[@Redneckeverything]

Do you use F or C degrees?

[@sam-ww1wk]

Did you preheat the baking sheet? At only 220 would take way longer than a few minutes for a cold baking sheet to get hot enough to melt anything.

[@ftrjin]

Gonna try it today . hope u dont ruin my Alp trip this friday haha :D fingers crossed and thanks for tutorial ! :)

[@mainstreamMTNguy]

I'm pretty confident in this method. Have a great trip!

[@drummondkoppernaes3173]

You don’t have to remove the bootboard or liner insole when heating?

[@mainstreamMTNguy]

No you don’t.

[@paulhomsy2751]

Excellent instruction and video ! Thank you !!

[@DaveSmith-t2x]

What about if my convection oven only goes as low as 300 degrees?

[@mainstreamMTNguy]

I wouldn't try it.

[@johngilmour6850]

Don't do it if your oven goes no lower than 300. Or get a new oven.

[@eminapanina]

I’m assuming I don’t cook my custom footbeds and pop them in after the shell and liners are heated up?

[@mainstreamMTNguy]

That is correct! Put those footbeds in right before you put your feet in.

[@gretabloomfield9619]

Do I throw my custom footbeds back in after I take my liners out of the oven?

[@craigpiefer7839]

Yes. Do not cook those footbeds.

[@WhirledPeas]

Great video. I have never thought of this. Would you cool the boots more quickly by wrapping in a wet towel to set the plastic once you have achieved the desired shape?

[@mainstreamMTNguy]

You could definitely do that!

[@playamamita1]

great video . Would you do the same thing with a BOA system boot? Got some Salomon S/PRo 130 BOA that are coming arriving next week . I would love to do that if i could

[@rickden8362]

Have you tried this method with the powerwrap models?

[@stephen-he4iw]

does this soften the flex rating of the boot at all?

[@mainstreamMTNguy]

@@stephen-he4iw No. Not at all.

[@goldentrichomeshydro4260]

Does this work with snowboarding boots?

[@Benzknees]

Would you use the same temperature with shells & liners made out of different materials than standard - e.g. pebax shells; ultralon foam liners? Also how did you arrive at that particular temperature?

[@mainstreamMTNguy]

From my own research on different boots and materials, 220 was the low end. In my mind it is better to go a little cooler than too hot.

[@valentintenev4339]

Do I put them inside the oven after it reaches 220 degrees or right after i turn it on?

[@craigpiefer7839]

Preheat the oven first, that way you know you are getting the correct temp.

[@TheRealWarez]

Your oven will absolutely roast anything you put in there while it's preheating... that's why preheating is even a thing. Also, make sure you take out the insole before heating and put it back in before the actual molding part.

[@grg2110]

The video makes it seems you turn the oven to 220 degrees on convection without preheating. Is that correct, put the boots right after the oven is set to 220 without preheating the oven?

[@JEEPIMPACT]

I would preheat

[@SuiGenerisMan]

Be very careful when putting on your boots, ovens can cause hot spots in the synthetic material and burn your skin. You should remove the straps too. They'll shrink when exposed to high heat and lose decades of their life span. All you need is a screwdriver, it's not difficult. You can also use boiling water, and pour it into a tub that fits your boots so they're completely covered by the water. It's the same process, you just use hot water instead of the oven, which is what custom shops use. Ovens are too risky of a process to use in our shop. Can't risk melting our customer's boots or causing them 2nd degree burns to their feet, so we use our laboratory bath and water. The heat doesn't dissipate as quickly as with an over. The water bath is exactly what we use to dye boots a new color too. Water bath is very useful and the industry standard for manufacturers, but it takes days to dry. If you're literally AT the condo of the ski resort - then yes, the oven is the way to go because there's no drying process time. If you're not AT the ski resort - use the boiling water method. It's much more uniform, the results are superior and it's far safer for your boots and yourself.

[@MrFitboss]

Do you have to take the liners out of the shells to heat ?

[@mainstreamMTNguy]

Yes, that is the best way to do it! Thanks for the comment!

[@DerekKerton]

The more boot surface area you expose to the air in the oven, the more quickly and evenly the boot parts heat up.

[@torreyintahoe]

I used my smoker. My boots smell delicious.

[@mainstreamMTNguy]

How do they taste?

[@goranpettersson7757]

Is the temperature in Celsius and is it the same for all brands?

[@mainstreamMTNguy]

Fahrenheit! Sorry, I should have clarified. This is a good general temperature for most boots but you should read all the manufactures info. Thanks for the comment.

[@larsmoservice588]

[@kukac9653]

How to find out if my boot shells are heat-moldable?

[@sam-ww1wk]

Google it, or call the manufacturer.

[@fishslayer1994]

ok just did this at home thought i’d also shard my experience with heat molding. i got wide feet were talking WIDE so i’ve had my boots professionally heat molded for the shells and punched but still need to get the length sorted since my big toe protrudes a good 1/3in out. did this method 220 for 15mins for my k2 methods worked well used some tape on my socks to create a pad to push the shell. also u can leave ur liners if u like it definitely is a choice and don’t since your buckles down hard when you first get em on wait a good 15-30 mins for them to cool down then you can. i am in no ways responsible if you fuck ur shit. but good luck y’all

[@kryszczuk]

if you put any shells that have dyneema lacings in that oven you can kiss them goodbye.

[@connermartin7558]

WOW hey im a professional bootfitter and DO NOT PUT YOUR BOOTS UNSUPPORTED ON A LEDGE AFTER HEATING THE SHELL. YOU WILL WARP THE SOLE OF THE BOOT AND EFFECT HOW IT INTERFACES WITH A BINDING. Everything else he did was fine but THIS WAS NOT. an incline is fine, but on a flat board or something not with just the toe on an incline. jesus christ.

[@connermartin7558]

HE IS CONFUSED. we use a 2x4 to support the shell when we are molding JUST THE LINER (to get the heel in the back of the boot) but doing it with the shell like he did here can warp the sole. idiot.

[@connermartin7558]

a 2x4 with a piece of plywood to support the rear and front lug of the boot while molding wouldve been great advice, but his advice here is dangerous.

Use a friends... or "rent" a countertop convection oven/toaster from your desired location... Amazon, Walmart, etc.... (return the oven when you are done. AKA: rent it for free).
