Wow.  You’ve given me a lot of stuff.  Here.  I have homework.  I have no idea what a talus is or how to make sure it is moving.  Will get on it.  

I definitely feel it’s something biomechanical that is keeping it in a pathological state.  
Do you mind if I follow up with you regarding specific question on some of these things?  I’ll do my own due diligence then hit you up if it still doesn’t make sense.
