You could also heat the entire shell in a low temp oven at home. Wrap in a towel first. 200 degrees. Wear gloves. They get very soft. This guy is excellent.
For less bubbling when working with grilamid or other PA plastic types, keep the heat gun moving constantly and completely remove heat every minute or so to let the heat on the surface of the plastic sink in. After that, back to the heat, keep it moving. PA plastics are lower density/have more air in them than TPU plastic types and so they insulate better/are harder to penetrate with heat. You’re right though, bubbling doesn’t matter. 100% cosmetic but it is pretty easy to avoid if you want to keep those boots pretty.
Your channel is so good. I mean Schirmer is awesome but he isnt showing us how to punch our boots. What do you think of the Cochise HV? I have a set of Mach 1s that I heat molded once and its been 3 years of comfort. Hoping to find a shop with a set I can try on.
Thank you for the video. Now that the ski season is drawing to a close, how did this work out for you? I have two different sized feet, which means that I have to buy two sets of boots-25.5 and 27.5. This limits my selection due to cost considerations. Skied for 20 years with a boot two sizes too big for my left foot. I couldn’t afford to buy two sets when I was younger. Not ideal, but I still enjoyed the sport.
The seasons just getting started, we tour through June here. I've done this for years and never had a problem. It's literally what bootfitters in ski shops do, they just have presses and better tools to manipulate the plastic. But they still blast them with heat guns. I know people who get two different sizes with climbing shoes. In ski boots I don't think it is a good idea. You'd need two different mounts and the two different sizes will also come at different heights, so one will be taller on your shin than the other and will be wider around your calf so it will close differently. Go to your local bootfitter- I would think you could find a 26.5 that one boot could be punched a ton to accommodate the 27.5 foot and the other you can add foam and shims to to accommodate the 25.5. either way not ideal, good luck.
I don't use a thermometer, I only do a minute or so at a time testing the plastic as I go to not overdo it. The second I apply force and see some movement then it's ready. If plastic won't budge, keep heating. There are forums that discuss particular temperatures for grilamid, pu, etc. But I don't find that necessary. Temperatures vary based on plastic type and thickness. So it's not as reliable. Just heat until you can make the punch you want
What temp do you set the heat gun to? And about how long did you heat the shell for? Curious how you tell when the plastic is ready? (before it’s too soft!) Punching a Scarpa Maestrale RS specifically so grilamid with carbon in it.

@@thicccboyztv sweet thank you! It totally worked to just heat it up until it started moving (with some force). Easier than expected with your tips. I also didn't use a thermometer, but my heat gun has adjustable heat and I set it to ~500 degrees which was perfect (no bubbling or scorching).
I learnt the hard way to do not perfectly be fitted in your ski boots. After started getting tired a poor boots fitting becomes VERY CRITICAL NOT ONLY for our feet also for the other muscle and joints coming to rescue us for that sornes or pain.......doing this over and over ended up developed a knee, calf or heaps injury. Not joking!
Raising the foot up within the boot to where the last is widest. Boots taper narrower at the bottom. Or heel shims for forward lean and ankle modifications
Hi mate, just came across this video. I have also punched this boot with good results. Can you compare the Zero G Tour Pro against the 2024 Maestrale RS in terms of skiing performance and stiffness? I have the ZGTPs and find the stiffness just right, pretty smooth and no brick wall feeling. How does the 2024 RS compare to that? Due to strangely bad availaibility of 2024 Scarpa gear in my area, I would have to mail order. Thanks!
The maestrale is a lot stiffer than the zero g tour pro. Skiing performance is mostly affected by fit and stiffness preference so if you like a softer smooth flex like the zero g the maestrale RS will be stiffer and you probably won't like it. It also has a more defined heel pocket. The maestrale also has more forward lean, and better skinning range of motion. It also has an actual elastic booster strap. It's a better boot for those that need more stiffness and those it fits. But the zero g is a fine boot if it works for you.
Thans a lot! Matter of fact, I find the lean of the ZGTP plenty forward already and the flex to be stiff enough. I found both lean and stiffness of the quattro XT and SL too much. Seems the Maestrales have quite a bit of Quattro DNA in them.
great success with my radicals... thanks for giving me the confidence to try this out

Damn, I lovw getting permission to do the dumb shit I was planning to do!

When using a temperature gun, how hot should the pa plastic be before working with it?

what would you recommend to use for the shims under the liner?

I also have a 2023 RS here, which with an Intuition Pro Tour feels really good too, quite similar in flex to the ZGTP.
@@danieljakowski7799 yeah they do, but different anatomies need different stuff. Good time to have options
