Was going back to 8.5 but not skiing like I was able to, I think I will go back and get another opinion, He seemed to be checking and re checking the chart.... got me thinking again now!!!!!
My worry is that I don't see how a Din setting can relate to stabilising your achilles. All that a Din setting does is to adjust when the binding will release the boot. Any achilles support will have to come from your boot.
My stats:
6ft
14st 4lb
Ski: black runs and off-piste (fairly aggressively)
and my Din's are set at 8!! I have never had a problem with them releasing when they need to either.
Do you ever find that your bindings are releasing when they probably shouldn't have?
it is down to how aggressive you ski not just the slopes you ski. cuz if your happy skiing at a 5 leave them there if not get someone else to set them.
