Binding question

No

i'm no expert but yeah i think that's a big issue and you shouldn't use them for anything (beyond maybe in your backyard if they seem to click in okay)

These bindings would be fine without the rubber tip if they weren’t so old. The bindings are dangerous to ride because they might be worn out and break when you are skiing. The dins also look to only go to 4, so I would recommend to go to a local trading post and look for a pair of newer skis if you want to use them this year. You can also go to ski shops or ski companies at then end of the season, and buy their demos for cheap if you want to start skiing:)

As others have said, those are toast. They're also a kid's binding.
