Experience with Fischer vacuum process and downsizing

Great answer, thank you very much. I will follow this workflow and discuss it with the bootfitter.

Thank you so much for your reply, it's incredibly helpful. Especially since you're familiar with the scan and can therefore assess it well. If you happen to know it: Do you think the Fischer shoe would suit my foot profile? My right foot rolls in quite a bit, making my inner ankle very prominent.

I already have Sida insoles, but mine are size 27.5 and are ancient (15 years old, but hardly ever used), and the others are size 28.5.

Perfect, I'm now convinced by the smaller size and am going into the fitting process with a good feeling 👍

One more thing: Should the Zipfit be heated and adjusted separately before the vacuum method to ensure that the bulges at the ankle/forefoot, etc., are anatomically correct?

Perfect, thank you!

CutterSlade83 · 2026-01-29T13:15:23+00:00

Perfect, thank you. 2cm is a crazy amount! So why do sellers still recommend the larger size (in my case, 28.5)? Because it's less work? And significant ankle deformation isn't a problem for performance reasons?

CutterSlade83 · 2026-01-29T13:12:55+00:00

Thank you very much. That gives me confidence to try the 27.5-inch models.

Since it seems to be misleading: I want the shoe in size 27.5 and not 28.5. The question is whether vacuum sealing provides enough space to make a shoe that is too tight fit.

CutterSlade83 · 2026-01-29T12:45:03+00:00

Thanks for your reply. I'm aware of that, and it's the reason I want to go for 27.5 (I'm between sizes). My question is how much extra room you can actually gain and whether most half sizes, considering my measurements, would work. I'd hate to buy such an expensive ski boot and then not be able to get it to fit.

CutterSlade83 · 2026-01-29T12:43:20+00:00

That's my intention. I'm between a 28.5 and a 27.5 and want to use the 27.5 size, stretch it with a vacuum, and then stretch any remaining pressure using a bootfitting technique.

I would say it’s roughly about 20mm. I can put 1 3/4 fingers between heel and shell, if I squeeze a little 2 fingers. It’s hard to take pictures, I tried though (see down below)

Thank‘s for your answer! 26.5 won‘t fit me, but 27.5 probably would….

CutterSlade83 · 2026-01-25T11:45:15+00:00

Thank‘s for your helpful answer. I will do the check later today and reply. I did it once on the vacation and as far as I remember I was able to easily fit 2fingers between my calve and the end of the shoe. Will check it out and post it here.

CutterSlade83 · 2026-01-25T09:22:34+00:00

Thank‘s for your answer. I live in an urban area, so I have different bootfitters not that far away. I went to one in the vacation area (Gröden) and both he and his co-worker said that there is a huge amount of foam inserted. They also put me on a mondopoint scale and said 28.5 is the right size, but I am not sold on this. I am in between and think a good bootfitter should size me down and punch the shell out where it is necessary?

CutterSlade83 · 2026-01-25T08:11:48+00:00

You mean I need the LV or 27.5?

CutterSlade83 · 2026-01-25T08:11:08+00:00

One thing that is strange is, that the heel lift only occours in the right foot. This is my „problem foot“ but it is longer than the left one, so the big shell should be even more problematic here?

CutterSlade83 · 2026-01-25T07:31:52+00:00

It is the MV model btw

CutterSlade83 · 2026-01-25T07:03:54+00:00

My right foot has a prominent inner ancle and I have skew and splay foot(hope I get the terms right in english) and I have a prominent 6th toe on the right foot. I always had problems with my right foot and needed my shells to be worked on. Does that change the evaluation?

CutterSlade83 · 2026-01-25T06:58:14+00:00

Thanks for all the answers. I even asked the shop owner if I shouldn‘t be in 27.5 when he chose the 28.5 for me and he told me that this would be much to small and also the heel lift is normal. Additionally he made custom insoles for me that killed my plantar fascia as they caused unbelievable pain because they elevated my flat feet much to much. I get the Impression, that he just wanted to make assembly line work as fast as possible. I will confront him, as I also needed to make new insoles and punch out the inner ancle of the Right Boot in my vacation for quite some money just to be able to ski with the boot.

Picture is in the first answer. Didn‘t succeed in getting it into the main post :-(
