Din???

post #1 of 8
Thread Starter 
Hi, I am 5 feet 5 250 pounds.  I am a intermediate -advanced but am not too agressive.  I took my skis and boots to a local shop and had the bindings of my new skis/bindings adjusted to my boots.  Even tho I was skiing expert runs last year (had injury which caused me to put on weight, so am more int right now) I am not very aggressive so I told shop I am a level 2.  They set the din to 10.  I was skiing today, and fell.  I was going slow and fell forward.  My left leg didnt come out of my ski at first, and my heel came up like 2 inches up the boot (like 1/3rd the way OUT OF MY BOOT) before my ski came off.  I was on the snow for a while because my knee hurt, finally made it down but have a strained knee.  I dont have alot of money so usually just do my bindings myself, I think in the past I have set them to like 8.  I paid like $50 to have my bindings done and new skis "tuned".   The shop had me sign something that they couldnt test the binding because they didnt have the equipment (think pressure testing?  Stress testing?  Something like that).  Was my din set correctly?

10 sounds high, since I'm 6'6", 260lbs., Type 2, and they usually set mine to 8.  But you need to go by the adjustment chart for that type of binding.

If they didn't have gear to do a proper release test, that's a bad sign.  I wouldn't have my bindings mounted/adjusted if they couldn't check them afterwards.

If they don't have the equipment they have actually done nothing but made a guess. Seems like easy money for them. DIN 10 seems very high if you told them you will take it easy! Ofcourse I can never tell exactly because I can't test them... oh, they couldn't either.

If your boot sole is around 300MM  that sounds about right.  Being that heavy and taking a slow fall is going to cause trouble.  The other option would be to set your din too low and have you walk out of the ski at speed unexpectedly.  and you might have been hurt much worse.

Leave the shop guys alone.

Hint I test the release on all my bindings by walking out of them Forward and toe release.  I do this on snow while not moving.

 there is alot of wrong with your post....

your foot shouldnt be able to move that much ever while skiing even in the process of a fall. having boots that loose nont only makes it hard to ski but enhances the chance to be hurt.

10 is high for someone with out strong ligaments and muscles, just get a screw driver turn it down a couple clicks probably to 6-8ish I know DIN is suppose to be an exact science it aint, because every binding is different and every skier is different.

even the same skier on the different skis might require different DINs. my DIN ranges from 6-13 depending on what I am skiing and what I am doing that day. I have learned to set my own and with that said I have nearly had my leg taken off at 6 but have prereleased 10 and have had 13 come of in fall like its nothin. Basically its a setting it cant stop and injury but it can help.

It's deja vu all over again.  Question pretty much cooked to well-done in a cross-post.

Whether the DIN is set right or not isn't as big an issue as your boots not fitting you correctly. Before you go back to the shop to complain about the ski set-up, I think you should get to a boot fitter.

Well lets look at a DIN Chart.  I got this one off the internet.


 

DISCLAIMER: This chart is for information only. Always have your bindings checked and adjusted by a professional.

At 5'5" you are on line J, your weight puts you on line M.  According to the chart directions you use the line closest to the top of the chart.  So use line J.

Since you indicate you are a type II skier drop down one line to line K.  I'm going to assume you are under 50 so we won't move back up one level.

You don't indicate a boot sole length so we can't get any more accurate than line K.  However, note that the highest DIN setting for this line is 6.5.   Make your own conclusions from there about where your bindings were set.

Remember release bindings are designed to help protect you from injury.  If you decide to jack up the DIN settings you are defeating this important safety system.  Do so at your own peril.



As a side note: I have found that high testosterone levels cause certain individuals to jack up their DINs to super high values.  Me, I ski at a skier level of Minus One for my binding settings.  (DIN 4.5)  I'm an expert skier and I've never "pre-released" and I can ski hard.  I understand why professional ski racers use high settings.  However, 99.9% of all skiers can use the recommended settings and not have problems.

I also think a lot of "Pre-release" problems are caused by poor or unrefined technique.  (Man can I see the slings and arrows coming my way now.  )
