To be clear the DIN stays the same, the heel piece is literally sliding back (widening) and that's what causes the ejection.
They're mounted on S7s if that makes a difference for some reason.
Any way to permanently fix this? I'd like to not drill new holes into my skis (even though I'd like touring bindings eventually), so getting new bindings is a last resort. Also I'm a baller on a budget.
Thanks dudes, love you.
