Boot stiffness

post #1 of 19
Thread Starter 
Is the their such thing a universal flex index in boots? In many magazines boots are listed with a flex between 80 and 130 (for high end boots). Are these numbers comparable between brands.

For example, I was told that salomons X-wave 10 (listed at 110) is softer than Langes L10 (listed at 90- not the race stock version). If so, is the wave 10 too soft a boot for an aggressive all mountain skier who sometimes races. Being 6'3" 185lbs probably makes a difference. Other boots?

My understanding is that the flex number is internally generated by each boot manufacturer and compares only to other boots made by that manufacturer. It is not a Universal flex indicator. So, a Lange with a flex indicator of 90 may indeed be stiffer than a Salomon boot listed as a 110, but a Lange with a 90 flex s/b stiffer than a Lange with an 80 flex.

If you are looking for a stiff boot, try the Technica line.

Then I've heard differently. The flex index if not exact, is fairly close, with the exception of Technica. Techs run theirs differntly and can't be compared.

My Salomon Superforces were 115. I've seen some around 130 or so! Me being short (5'4")I jsut don't have the leverage to bend those things. At race speeds I might do better, but they rebound too fast for me. it was stated that maybe my skiing was at fault for these boots throwing me into the back seat. Maybe so, I don't know. I do know that I'd concentrate on staying forward above all else and still they'd throw me back now and then.
I got them de-flexed and this solve my problems. Judging what others say of my skiing I don't have a back seat problem. But stiffness and foward lean can cause this to occur with some people regardless of their ability. It may be that these boots would ract properly at higher speeds, but I don't race.
The shaped ski does call for a softer boot. How soft or stiff is up to you and your style. I think a well fitting boot which responds to what you tell it to do is more important. if stiffer is always better let's all get boots made of steel! Just kidding.
Now let's see... where did I put those old leather boots?

I got TAG's back on this one.
No standard for boot flex index.
They may be close but as stated a 110 Rossignol Flex is different than a 110 Salomon Flex.

Actually stifness recommendations vary between coaches. For off piste skiing some recommend softer boot which allows for wider range of motion and does not throw you in the back seat like jyarddog described. So even if you are aggressive skier spending most of the time off-piste you might like the softer boot.

If there is less standardization in flex rating, is there any consideration in the future to try and standardize this?
Getting into boots from different vendors and checking different flexes one can feel the differences. This, true, is not very scientific. Take a 90 flex Salomon against a 90 flex Nordica- they might feel about the same, but may differ a bit this way or that. has this not been standardized because there is no safety issue or other reason?
It would be nice to have a DIN flex or something like that around. [img]smile.gif[/img]

On my X-15/Icon Carbon combo, I find the only thing a stiff boot provides me is sore shins!!

Any performance degradation is minimal.

I had the same flex index question when boot shopping a couple of days ago. Ski shop guy said the flex index is all relative to a manufacturer's boot line, and you can't compare the index across manufacturers. A 90 Nordica isn't equivalent to a 90 Salomon. But a 90 Nordica is of course stiffer to a 80 Nordica. Just use it to compare boots within a brand.

I was surprised, too. Should be a standard.

Demo, demo, demo.

So, my real question now is which boot is a stiffer, higher performing boot. The Saloman x wave 10 or the lange L10 ( not the race version). I want to demo but realistically can not. It is very hard to feel things like lateral stiffness and edge control in the store. Both boots fit well with the L 10 having slighlty less toe room -meaning my toes hurt and are praticaly curled in the store. I want to be in the smallest shell possible.

OK, if they hurt, then forget about it, go with the Sallys, but check out Technica if you can as well.

I would personally suggest the solly course boot... it's just a bit stiffer than the x-wave 10 but it is a snugger fit with a firmer liner. much smoother boot than the langes; the sollies feel like you can roll them as much or as little as you want, with as much or as little (to a limit) shin pressure as you want to use. the langes give you major shin pain, pack out, buckles break, and your toes wont survive. I had L10 ACD's last year and solly courses this year. sollies are better hands down... I love them. totally comfortable and much better performance than the langes ever gave me.

I know the of the course boot but assumed (and told) that it was too stiff and not comfortable enough for all mountain use. What do you mean by sollies?
post #14 of 19
where can you demo boots?
post #15 of 19
Sollies --> Salomons

Try on as many boots as you can, here's a list of many of the top freeride boots:

Nordica W10.2
Rossi Freeride XXX
Salomon X-Wave 10.0
Tecnica Icon Carbon
Head FR 10.0
Atomic Beta Ride 10.50
Lange L10/Banshee Pro
Raichle Flexon w/ DD tongue
Dalbello PRX Comp
Dolomite Sintesi 8.5/9.5

If you want to be in the smallest shell possible than the best thing would probably be to try on just about every brand you can find in any store (I put up a little list just above) and then pick the boot that fits your foot shape and is comfy even when it is really close to your foot. Just about every top-end boot will provide supreme performance so the most important thing is fit. Again, try on as many boots as possible.

The x wave holds my foot very well except that my big toe is very cramped. My feet seem to be asymetrical- my big toe sticks out farther than the rest, and more to the inside. The sales man noticed this and suggested said he would be happy to grind the inside of the boot out to make room for this.

I also have tried the Atomic 10.50 and it did not hold my as well. Their were some pressure points that felt very strange. I suppose their last just doesn't fit my foot like the "sollies". It did have more room though.

Thanks for the help

Please explain your need for "All-mountain" performance as a Wisconsin ski racer. Back bowls of Wilmot? Steep and deep at Trollhaugen? [img]tongue.gif[/img] [img]tongue.gif[/img]

Good point! That is the only reason I have been able to survive in the boots I have now.

I used to live in CO so have had more experiance than a once a year trip.
