How much can the flex of a boot be changed

post #1 of 14
Thread Starter 

I am going to buy a pair of tecnica Inferno's (race) but I struggling with which flex to get.

The 110 seem way too soft in the shop and the boot tech feels the same way. No one has a 130 in my size to try so I would have to order it with have the opp to try it in the shop first.

 

My question is if I get the 130 and I feel I need to soften the flex somewhere between the 130 and the 110 can I do this without dramatically compromising the integrity of the boot?

 

I know it that two screws that can be removed to soften the flex but that seem like it would negatively impact the interaction between the upper cuff and the lower boot...would it?

 

I am told the best way to do this is by extending or making "flex" cuts in the back of the lower shell......is this the best way to go?...will it get me somewhere between the 130 and 110 if needed?

 

I don't think I am going to need to do this but I don't want to buy the 130 and not be able to adjust if nesasery.

 

Any advice would be greatly appreciated!,,,,

Philpug has some experience with softening a Tecnica 130.  I know it can be done, but not sure how much.

Taking about 1/4" off the bottom of the upper cuff by the 3rd buckle will also help. 

 

I don't think I am going to need to do this but I don't want to buy the 130 and not be able to adjust if nesasery.

I softened mine a bit. See the red above.  The 130 is a big step in performance over the 110 and you will be happy. See how the flex is before you do any work, you might be surprised.

Philplug,    Thanks for the input!   I know this is a subjective question but how much stiffer

Would you say the 130 is over the 110?

 

i  agree with you...I would keep the 130 unchanged and ski it many times before I made any changes that can't be reversed

 

i know this is not really relevant but in case it helps.....I am 6' 235 lbs ( I am not fat....:).  ). Skied for over 30 years.....I won't say how good/bad I am because it is like asking a mother how pretty her kid is.....but I do race in a beer league and have always had higher end boots

 

I am going to pull the trigger today or tomorrow and don't want to make a mistake......

Just from my observation:

Majority of the people get stiffer boot, that they don't need... Everyone says you have to be able to flex the boots in the shop and they will be OK. It isn't always the case.Unless you ski only on boiler plate and or water injected snow you might go with a little softer boot... Plus the flex seems to differ from brand to brand, a lot.With Fischer and Nordica seems to feel stiffest..

 

 OP, How much do you weigh? For example Phil has the same boots-130 and softened them and he is 190lbs/if I am correct...

J. Schafner/Starthaus, got Fischer Vacuum Pro's in 130???

I am sure Phil would chime in.. I know you can get stiff boot and soften it, not the other way around.

 

Cutting the lower boot on the sides and or back can soften it... Some of the brands,like Nordica/I think/have a little markings inside the rear part of boot...Removing the bolts/rivets from the cuff is not right at least for 2 reasons:

- It will give you even a little more, than necessary forward lean/not needed with today's ski shapes

-Power transfer between cuff and boot shell will be delayed significantly..

I am with you on your first point...I started the adventure thinking I will go softer....I got concerned when both the fitter and myself though the 110 is way too soft....since the shop didn't have a 130 in stock makes me feel confident he wasn't trying to up sell me or put me in something they "have in stock"....not that I think the would do that...

 

As far as my weight goes I am 235 lbs 6'....not chubby....I have to keep making that comment.  :)

You should be debating between 130 and 150 imho.  Get the 130; you won't regret it, (unless your 30 years have been repeating the same mistakes over and over again.  In which case, you will be thrilled when you finally get beyond that plateau).

Couple of quick observations:

 

1) Tend to agree that 110 is suspect for your size. But some people are talking as if flex numbers are precise, comparable across brands, and linear (meaning that the difference between 110 and 130 is the same as between 130 and 150 etc.)

 

2) So have you tried any other brands? Say in 120? Or with adjustable flex? Given that a good fitter can make most boots fit most feet, sooner or later, are you convinced that the Inferno is The One, even if you have to cut it up?

 

3) Consider that your boot creates flex by pressing a cylinder against an overlapping shell and causing the juncture to widen slightly or deform. And a PU shell gets stiffer with less temperature, but also, far as I know, in a non-linear fashion. So if it feels too soft in the store, it may feel too stiff at 5 degrees. Cutting it may make it softer, but I doubt it will help the precision of the flex. (Note Phil's comment.) So where do you ski? Is precision important? Or do you spend a lot of time on the backside?

 

4) Most people buy boots that are too stiff IMO (agree with Andy here). Are you sure  you want instant transmission of force to the ski tips? That's a good thing carving precisely, maybe a bad thing in bumpy powder. The forward flex of the boot may have less to do with modern styles, especially on fatter rockered skis, than does lateral stiffness. (Salomon was making this point over a decade ago, incidentally.) OTOH, a stiffer boot often has a more precise fit and more plastic on the sides, too. It'll make you happier slicing up groomers. So what kind of skiing are you using this for? High speed sweepers on 70 mm race carvers or trees on 110 rockers or neither? And do you see yourself as more of a tip pressure guy or a lateral pressure guy?

 

My .02 anyway...

Well I spend 80% of my time in New England and 80% of that time on the front side. The other 20% is spend on trips out west trying to find the fun stuff to ski.

i have everything from Volkl race tigers race stocks to a pair of gotamas......i now spend most of my time on a ski that is 88 under foot and have no issues running it hard on the front side.....

 

 

I am kinda sold on the Inferno.....tried the Lange and Nordica's. But the infernos felt a lot better on my foot.

 

 

Dont get me wrong....I went into this thinking I needed the 110.....as I mentioned the boot tech felt it was too soft for me......plus the 110 is cheaper....my wallet and my wife like the 110 better.....   :)

Well, given what you're adding, will have to go with the 130 contingent. NE doesn't get that cold, compared to Montana or Wyoming, and if we're talking frontside groomers you'll want the tip pressure. Sodden afterthought: Have you looked at Salomon's? I've skied Technicas, and IMO the other brand with the closest fit are Solly's. The Impact 120 CS is a nice boot, lot of easy customization features, 100 last I think, can be stretched to 106.

So, you are not fat, I guess big boned then? LOL. At 235, unless there is something unusual with leg lengths and mobility, the 130 should be fine. Oh, replace the power strap with a Booster, huge improvement. You struck oil with the fit of the Inferno, if you like the fit of the 110, you will be fine with the 130.

It funny you mentioned the Solly's....they where up there on my list with the tecnica. The fit felt great and I heard a lot of good things about them....it came down to a few things....but mostly the tecnica's felt good from a "stance" standpoint for me...granted that was in the shop.....

 

I did like the concept of the shell being easily moldable.....I have a bunion that I usually need to have the boot punched out for....

Absolutly......the booster strap is the first mod I make......it is like American express......don't leave home with out it

 

 

 

 

This fourm is the best.......I really want to thank everybody for the great info!!!

I was banging my head on the wall and doing all kinds of goofy Google searches trying to make sure I was doing the right thing......and getting no where....

 

Based on the feedback you folks provided me and my gut feel I am pulling the trigger on the 130's.......I am looking forward to skiing on them!

 

 

Thanks for the help!!!!   beercheer.gif

I wanted to follow up on this post.

 

I now am the proud owner of a pair of inferno 130's and I must say you folks were spot on...the flex is perfect for me and I feel I will have no issues once they are out in the cold.

i am not sure if it is the allure of having new boots or not but the Flex of these boots seem much "smoother" and "progressive" to me then boots in the past or even some boots that I tried on in shops this year.......I am not sure.......but I am really fired up about getting these on the snow....

 

 

Thanks once again for the help!!
