Reducing DIN setting on rear half only of binding?

post #1 of 11
Thread Starter 
Hi all!

After a fall at around 60kph, I was thrown forward my skies and over
extended my left calf in the process of de-biding.

Now, twist release if very easy and does not even offer discomfort.
But it seems heel vertical release can hurt me.

Is it wise to reduce DIN on the heal while leaving the toe as set?

My bindings are set to advanced for my weight-size-sole.(DIN 8, 6'4", 240lb, 347 sole)


Thanks for any advice.

Have you considered the possibility that it was your boots flexing too much and not the binding release setting which lead to your stretched calf? At your size, a DIN of 8 seems pretty conservative.

Well, the Tyrolia service book says that I should be at DIN 6 at novice, then 7 for intermidiate
and the 8 for advanced. So I do not think it is conservative in that respect.

However, you raise an important point with the boot flex, but unfortunately,
my foot shape prevents me from having a boot with less than a 103 Last,
so I have S90's from Head with a flex of 100 to which I added a World Cup Booster
strap to get 10 more...

Hmmm.....

There are many things going on here, and facts to know. What binding do you have? What is the binding din range? What is the binding weight limit? What ski are you on? Age? skier types?

Sure!

The biding is an HD14 from Tyrolia-Head
The range is 4-14DIN
The biding weight limit is 275lb
I skii 08-09 Monster Chip skis in 183cm at 78mm under foot.
I am 36 and I am advanced and can ski any pitch in piste.(double diamonds)
There is even a 53degree pass where I ski and it does not scare me and I can wiper it,
though I do not think I could carve that type of pitch.
I do fluff as well but with other skis.(Mojo 103's)

As a side note, I do extensive leg exercises all rear round with hiking and biking in the summer
as well as scuba diving which keep the legs highly involved! So I have strong legs!

Thanks!

Does it only hurt your injured calf to step out of the bindings with someone standing on the ski tails?

It could be that you damaged your calf muscle straining to apply pressure through the ball of your foot and in a manner that was not caused by the heel retention setting on your binding; your were likely pushing down hard with the ball of your foot trying not to go over the tips.  Once injured, it could take quite a while before a normal setting won't hurt it. 

The DIN levels are risk acceptance levels, not ability levels.  8 seems to be a low level for 240 lbs, but 247 is a looong boot sole length.   I would leave it at 8 or maybe lower just that side and take it easy until the injury is healed (provided you can ski on one ski for a short while)

Hi Ghost. Yes indeed, I could lower that side. And I will be wipering only when I get back on skis, probably on Monday
as I can now walk normally. I will do greens only though.

I have not tried rerleasing the heal yet, however, I remember I could do it fine
but I would involve my shins to a goor degree so my calf was probably not as
solicited as it was with a face plant.

In your experience, so you think a 100 flex boot is insufficient
considering I have A-E skies and my ice skies are XRC1200 which are E level?
The booster strap is supposed to raise the flex by about 10 and has many other
qualities, but it does not raise heel to calf flex, that is for sure...

Thank for the advice!

I think a100 to 120  flex is fine......for someone who weighs 165 lbs.

But no boot exist with a 150 that will not make want to cut my legs off with an axe...
I would need a more constructive suggestion... At 30.5, I am already
at the limit of ski boots and most race boots dont even go to 30...

So there has to be another solution...

I guess I will have to ask a boot fitter for other options...

That's why we have boot fitters.

With your set up a din of 8, sounds low for what you are sking. Most of the guys I ski with, ski a din range 9 to 13, that ski hard, and fast.( check foreward pressure too ). The charts have me as type 2 with a din 6.75, and I prerelease on blue trails, as a type 3 my din is 10.Still to low for the steeps,and big mt. skiing.

What size shoe do you wear? A good boot fitter will help you, find the right size, shape, and flex boot. A geat boot fitter can get you in a boot 3sizes smaller then your shoe size. My fitter got me in a 29 boot, and I wear a 15 shoe. My boot fits like a dream. 

If your not racing why would you want to go over 130 flex. There are a few boots cut full
over 103 last with a flex of 100 to 120.  Solfter boot may help you. I know guys over 300lbs that ski boots in that 100 to 120 flex range.

Find a boot fitter.
