Replying to Are my looks broken?

This weekend I hit a cliff and broke the little plastic wing part (where the toepiece clips in) of my Look P10s.  I lost the piece in the snow and I just kept skiing without it.  Someone told me that that piece is part of Look's frictionless system that helps you release on twisting falls.  I want to know if my bindings will cause me problems down the road.  They work fine now, and I think that I could maybe get a replacement piece from a shop.
