Poster: A snowHead

I feel this is a much better way of understanding the flex of ski boots, and why the tests while uniform and accurate across all brands there are differences when we compare them. We can also have a thread that could accurately tell you the exact ski boot flex you should be using, however temperature, and speed will have such a dramatic effect on that number the boots performance would change. it's really a mute subject.
A flex rating of 100 , measured at 23°C ,assuming we're using a poly ester to get that number will stiffen by a factor of approximately x5 at minus 10° thus the real world resistance, forgetting biological variables, with have 500 flex.
PP x6-7
PU Ester x5
PU Ether x4
PA Grilamid x3

A 100 kg person travelling at 50kms per hour, i think, help me physicists, would require 500nm of resistance not to take the boot beyond it's strength, thus snapping their achilles if caught in a white out and the slope/piste climbs suddenly.

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

Don't take this the wrong way, but are you a generative AI?

Anyway, snowHeads is much more fun if you do.

I suspect this is going a bit off piste. If the boot flex index is a measure of energy absorption over a range of flex then yes, increasing the load will mean it will flex more and could potentially strain the achilles if it flexes beyond the skiers range of motion. But I would think it's better to choose the flex of a boot on a skier's need to apply an appropriate force to the ski at an angle suitable for balance and performance rather than worry about it as a safety concern. I don't know how many skiers end up with even a strained achilles from skiing but I'd have thought we'd have heard about it if it was a common problem (and would probably have a different release on the rear ski bindings to protect against it).

or perhaps it is the years of smelling the fumes of slowly softening boot shell...

would need a microscope to even be able to see 130nm ski boots, let alone feel them
