last year i had some serious shin bang halfway through the season. i got sick of it, so i stopped skiing for a week and iced the shit out of my shins to heal them up. then i took "don't land backseat" to a whole new level and only landed switch when i was in the park. seriously. even off of rails. i forced myself to land backwards all the time, and not once did I experience shin bang for the rest of the season.
The cause of shin bang is landing backseat and or backslapping. you can try to prevent it by getting properly fitted boots and strengthening/ stretching, but as soon as you land a little bit backseat on some hard snow its going to come right back. full tilts do nothing, unless you get a really soft tongue, in which case all they do is soften the pressure on your injured shins. just get tight fitting boots (roughly 2 sizes below your measured size) so you have control, heel hold, and ankle stability, but try to never land backseat.
i now consider landing backseat worse than a crash, because when i crash, I rarely get injured, but EVERY SINGLE TIME i land backseat, i know that im incrementally damaging myself.
ahhh. personal anecdote over. now lets brainstorm ideas to prevent this harmful injury with TECHNOLOGY.
how about this:
boots with backplates that go up almost to your knees, that are spring loaded to keep your calves in front of your heels, but have elastic travel to give out when you do backslap. I call it the SUPERSPOILER.
ill post some pics of my drawings later.
