Fischer Vacuum RC4 130 for high volume foot

post #1 of 13
Thread Starter 



I'm preparing for the new season and I'm closing in in a Fischer Vacuum RC4 130. At this point I must say Im on a very high volume boot, high instep, wide feet (atomic LF 90 with superfeet blue).


I tried an unmolded one just to check and it actually feels good. I was shocked, because I could never slide into a race fit boot (or any boot with less than 100mm last for instance) and stay on it more than 30 seconds (or buckle it properly), since I would feel pain in the instep or side of the feet area (and those are only the times I could actually get the boot in).

I'm just worried about 2 points before pulling the trigger:


* The RC4 is supposed to be a boot that is not for high volume feet. Still it felt extremely comfy when I tried (I seriously could not believe it, I went to check if he didnt give me a wrong bigger size, I actually wanted to try a Ranger 12 but the dude said "try this RC4, trust me"). It is said to have 93-103 mm last so I suppose before molding it was on the upper region, and since the last varies with the boot size, it seems it could take my feet. Should I be worried with this?


* I tried the 28.5 (only one available, sigh) and I couldnt feel my toes touching the front of the boot when I was in relaxed stance (I can do this in my current boot), which tells me maybe I could go shorter? As people say often that in the vacuum you only try before the molding if the length is good I felt a bit strange with this. Maybe I could go 28.0, I think 27.5 probably not, but since half sizes are not that different, maybe this is not an issue. I'm just worried about heel movement (it happens a but in my current boot), but since it will be molded, maybe this wont be a problem. I didnt have the time to do a shellfit test, but I will.


So except for these 2 points (volume issue and length potential issue) I couldn't find anything ringing a mental alarm against it, but wouldn't hurt to hear some opinions!

Not enough info:


What size feet---length and width (in cm)?


You won't know if it will work until you find out if the proper size (shell fit) has enough instep height.

Its about 27.7 cm in length and 10.5 for width.


I was reasoning the 28.5 was a hit because:
- my current boot is a 28
- the .5 should have the same shell as the .0
- I stayed buckled comfortably for a couple of minutes on it, with no signs of pain

with 27.7 cm long foot i would hope that in most cases you would fit without any problem into a 27.5 shell  the 105mm wide foot may or may not be an issue depending on your tolerance to soft tissue compression and how it was measured but it is not a super wide foot in a 27.5, just above medium


so without seeing your feet and doing a shell check it is impossible to say. but i would be a little concerned about the 28/28.5 shell being used unless there was another reason (i don't sell the fisher range so cannot comment on how the shell length is BUT i am pretty sure it is not going to be wildly off form other brands)

Thing is that we are in the last-boot-for-discounted-price territory :/


This boot costs one kidney, so I'm not in love with the idea of paying full retail or wait for the current year's selection


So there was no 27.5 available (maybe of the yellow RC4 which is narrower). The guy in the store when I told him about my length concern that the shorter version would probably find an issue with instep or width, which I find possible.

As Colin has said,


The 28.5 boot will be too big and require that you over tighten the shell to hold your foot still while skiing---you wouldn't want to find out that you wasted a kidney just to save a few $$$ and then have to go and donate the other kidney to get the correct size.


I measure 28.4cm and ski in a boot that was marked 27.5 (315 boot sole length) with no toe pressure issue, so you should easily fit into a 27.5 boot and have better control (a good thing).

You are asking us for fitting advice and bringing price into the equation as the over-riding factor.  Fine, just realize you are saving a lot of money on a boot that is too big.  If you put a 29 on it would be even more comfortable, less skiable, more sloppy on the hill, less comfortable on the hill but definitely more comfortable in the store.  Are you buying for the store or the slope?

I will check the other boots available, but the yellow racing ones I dont see as promising due to the narrow last value.


The length certainly raised my eyebrows, which is why i decided to crosscheck here. Its just that the vacuum can be sometimes... unnatural, to quote star wars.


I keep you guys posted!

Why do you care about the narrow last, you didn't advise that anyone has measured your foot width.?  Last does not vary with boot size in any boot I can think of.

Hi Lou


Its because  I could never even put one of those boots on my feet. I will always remember the day a guy gave me a salomon X3 "in my size" to test. 


For the 2nd point, I always though the last varied with the size of the boot (e.g. a 28 boot of model X would have slightly wider last than the size 26). If not only for the sake of proportionality, also because I've read many times in different places. For example here: http://www.skis.com/Buying-Guide-for-Ski-Boots/buying-guide-3-17-2012,default,pg.htmlOn

So we should go over a little terminology I suppose.   The boot does get wider as it gets longer because exactly as you say there is a proportion that must be maintained.  The "last" such as 98mm is the width of the boot in a standard size, in men's boots it is typically a 26 or 27.    As boot size increases boot width also increases proportionally so the last remains the same.  So as the boot gets longer it also gets bigger in all dimensions, which is why buying too large a boot can be such a big deal.


Experienced fitters with good tools can accomplish quite to seriously alter boot shape and many times it may be beneficial to put a wide foot in a narrow boot.  We don't know much about your overall foot shape, but for instance I often see skiers with a wide but very low volume forefoot and perhaps a narrow heel and ankle.  If I put them in a boot wide enough for their forefoot the rest of their foot is swimming.  So what do I do, I widen a narrow boot.


Today I had a customer that is a perfect example of the necessity of fitting the foot as a system and not simply fitting the widest part.

Off the scale narrow pronated feet.  Practically walking on his navicular but a "B" width Mondo 26 forefoot.  Came to me with a Mondo 27 Salomon Sensifit, which is just a big cave.  He has had five pairs of boot in six years and all hurt enough to limit his skiing days.  All were punched in the lateral forefoot and none had enough room to eliminate the extreme cramping he experienced although when he moved his forefoot side to side there was almost a full cm of space.  Everyone had missed the solution.


Narrow feet need narrow boots with in his case a footbed and dramatic room made on the medial side of the boot for his navicular.  We used a raptor 115.  I can't do anything to greatly reduce the dramatic pronation of his feet but I can make room for them to pronate without moving his forefoot laterally and that is the solution we'll use.

i think, based on what your fitter has done so far, i would find another fitter, or settle for mediocrity

mediocrity? is that near toledo?:cool
