After 14 years, ski bindings can really be problematic. The springs and internal mechanisms degrade over time, even if you're not using them. It's not just about visible rust - the materials become brittle and lose their ability to release properly when you fall. If the binding doesn't let go at the right moment, you risk a serious leg or knee injury.
The best thing is to have them checked by a pro. A ski shop can test the release mechanism to see if the values are still good. But honestly, after 14 years, even if everything looks OK visually, a lot of people just replace the bindings because safety isn't negotiable. The cost of new bindings is nothing compared to torn ligaments.
If you really want to keep them, at minimum check the condition of the springs, make sure there's no corrosion, and especially get them tested before you hit the slopes. But I'm telling you straight: bindings from 2012 are borderline. Honestly I think it's worth replacing them.
