I can see that as the boots go up the grades in terms of expertise of the user, the flex index increases, does this mean that better skiers, lean forwards more, and novices stand more upright, or is that boots for novices have less flex so that the skier can lean forwards on them without them moving?

sharon1953, the higher the flex the stiffer the boot is, and more force is required to bend (flex) the boot forwards.

Well, the person's real but it's just a made up name, see?

thanks, so what does the actual flex number mean? why is 100 stiffer than 70?

sharon1953, That's a question best answered by a bootfitter I'm afraid. A competitive skier would probably be using boots with flex rating of 150+, a boot with a flex rating of 70-90 would probably be decsribed as suitable for novice/intermediates, my main boots are 110 which are plenty stiff enough for me.

70, Plastic that resembles a jelly straight from the fridge
80, Plastic that resembles a moist chocolate pudding
90 Plastic that resembles a Coat Hanger
100 Plastic that resembels a iron girder
120 Plastic that resembles having your feet cemented by the mafia before being dropped of a bridge
140  You are a downhill racer the boot does not flex you have no circulation to your feet and they are crammed into a binding that will not release you better hope you dont fall!!!
It is basically how easy the boot is to flex the higher the rating the less the boot will flex and the more responsive it is. I am sure CEM or Small zookeeper will be along soon to explain the science and logic behind this.

Ordhan, thanks, that make sense now, so I think I will avoid boots over 80, the thought of moist chocolate puddings on my feet is wonderful, I won't know if to stop and eat my boots or drink some hot chocolate and cream

Ordhan, There are plenty of people here in Tignes skiing bumps and powder on 150 and 160 flex boots.
My new 150 flex Nordicas will flex slightly more than my old ones.

Do all manufacturers use the same DIN/ISO grading system with precisely defined test procedures?
It would be a first.

The actual numbers given as a flex rating on ski boots refer to the average number of Shore units required to flex the boot through 11 or 15 degrees (this varies between some manufacturers). The average is taken from something like 10,000 individual flexes using a metal ram at an ambient room temperature of ~22 degrees centrigrade.
The flex has nothing to do with the forward lean angle of the boot, this is seperate and can be altered by a bootfitter (much like the flex).
Stiffer boots are generally for more advanced/aggressive skiers or tall/heavy people who require more support. Stiffer boots are also made of denser and more responsive plastics but do not always relate to a tighter fit. A good bootfitter will be able to select a very stiff, responsive boot that is also high volume.
Right, lets wait for SZK to come and correct me

sharon1953, Alot of factors effect what flex you should be on weight and muscle strength being a friend of mine bought his first boots at flex 110 because he was a big Rugby player with legs the size or a redwood! Boot fitter got it spot on to be honest with him
rjs, Oh I know I have falcons cranked up to 140 because I am a big fat git.

Soft boots are for punters, stiff boots are for "core" skiers.

Alright soft boots are for finesse skiers, stiff boots for lard asses.

sharon1953, I have Salomon boots (falcon fat-basstad I think) and the flex can be adjusted easily just by taking out the two rivits in the back of the boot - flex goes down from 110 to 90 I think. I ski with them out all the time to be honest, but it's strangely comforting to know that should I have a Hero Moment I could put 'em back in and experience what Ordhan might describe as having my feet covered covered in plaster of paris by some hoodies.
Obviously, as you will already know, colour is far more important than any techy stats - Blue is preferred I think.

rjs, 160 flex?
rob@rar, disagree. Personal taste comes into it. I like a rigid boot. I don't do WC.

red 27, actually, colour is really important, differing pigments affect flex in different ways dependant on the design of the boot....Red seems to work just fine in the salomon race boot but Head found it unstable in their design so moved to the grey and spunk white colour that they now use

under a new name, Lange's WC boot for this year is 160 flex in ZC ZC flex, the true World Cup boots from Atomic are 150, 160, 170 should they be required

CEM, Thought you were taking the p1ss until I confirmed with the other pie eater who says you are actually speaking the truth-red boots go faster! What about green ones? Or powder poofy blue ones?

Kitty, poofy blue seems to go pretty quick based on the herminator

CEM, Been pi$$ing around with a few pairs of ZEZE all afternoon, chucked an atom bomb in one to see if it had any effect. None registered, no one died.

I agree that personal taste is the most important thing, but I did day that skiing deep snow didn't need stiff boots. On the other hand, skiing gates on an icy piste probably does need stiffer than average boots to get the precision required.

I heard a rumour that red didn't work too well for Garmont in their G1 too.

FAQ
My boots were red but as you have observed, they were a little wobbly so a couple of coats of blue radiator paint and now they're solid as a rock
