because the forward flex of the boot is primarily in the non-removable tongue, the forward flex is non-adjustable. A boot-fitter could cut portions out of the tongue to soften it but that is irreversible and might sacrifice the life of the boot.
That's why I said "primarily" and not "exclusively". With this specific construction, softening the boot is difficult because the lower shell is already cut where you would normally soften a boot. You are right that he could unbuckle his boot or remove his power strap to gain more flex, but I think that would lead to more problems.
how much do you weigh and what size boot are you rocking? Shinbang isn't necessarily due to the flex of the boot. Probably the way your skiing or an incorrect boot fit. A stiffer flex is going to help everywhere outside the park if your an agressive enough skier. Learn to embrace a stiffer boot helps wonders in the long run
"You put on your boots, click into your bindings, dust the snow off your skis, and head out for the chair, and it doesn't matter that you failed a test, didn't get the girl, or that your life is on a one way trip down the shitter, your world is right for the next couple of hours."
Whats size street shoe do you normally wear? Did a bootfitter put you in this boot or did you buy it on the internet? Is it loose around your calf. Do you ski backseat or do actually pressure the tongue? These are relevant questions.
I ski this boot with a booster strap, and Intuition power wrap. I could not be happier with it.
The boot is not really loose at all around my calf, i do actually pressure the tongue, however the occasional backseat landing is inevitable. but I seem to get shinbang regardless of if I've landed backseat at all. I was actually fitted, and i wear an 10.5-11.5 street size.
