Replying to Nose press is impossible

there are only two outcomes to my attempts at a nose press
1. my ankles lift partially in the boot (like one or two inches) and my whole body moves forward but not my boots or skis
2. I toe eject from my bindings
Two things have become apparent to me:
1. I need boots that secure my feet
2. I might need a slightly higher din if I cant put a little weight into a nose press without ejecting

The skis were black crows 186cm viators and I'm in the mid 170s
Thoughts? Are those conclusions correct?
