Replying to Bindings?

I have a recurring ankle injury and even though my din setting is in the right place my ankle is too frail to deal with it. I can't have a lower din either bacause they will pop out too easily. I was wondering what kind of bindings will really respond well in the right type of fall. I know marker griffons are like the really popular/nice bindings but are they also really responsive? I don't believe my current bindings (although brand new) have lateral release. They are some solomon bindings, not sure about the exact model. Can someone please help me with what I should do, I cant get re injured every season and have to pack up early.
