Replying to Do I need to re-mount my bindings?

Bought these skis off a fellow NSer, Blends w/ Tyrolia Attack 12. I think he said he has a 29 boot, and I have a 27.5, but the Attack's have a couple cm of adjustment and the pictures have the bindings adjusted to the smallest setting. I can click into the bindings fine, did a living room nose press and they didn't pop off, but this little gap has me concerned. Don't know a lot about bindings but I'm guessing something with the forward pressure will be off, hoping someone who knows more can shed some light on this.
