Help me figure out how/where to fix my boots

Here is the situation: I have nordica W12 boots that are 2 years old. When I bought them I searched everywhere to try and find the most comfortable boot. I even bought extra footbeds. They are blue footbeds called zip-fit (dont know if this is the brand). The problem is, whenever I go skiing my feet HURT really bad. Sometimes so bad that in the middle of the run I need to stop and unbuckle/take the weight off my feet. At the end of EVERY run I have to unbuckle my boots completely.
The pain is really sharp on the bottom of my feet and my feet get really cold, almost as if the circulation is being cut off. I think it has somthing to do with my pinkie toe being mashed agianst the rest of my toes stopping the blood flow (just a guess).
Is this a common problem? Is there a name for it? How do I get it fixed?
If there is a soultion, where can I get it fixed? I am in Vancouver BC?

Sorry for the lengthy question, any answers much appreciated, Whistler opens on saturday and I want a pain free season!!!

snowcovers in van or whis

I bet the boots are too big, so you have to buckle them too tight, so the circulation is cut off and the foot is crushed,

Thanks, I'll go check out when I can. it would suck if they are too big. I paid a lot of money for these bad boys.

remove the liner
with your toes touching the front you should less then 2cm behind your heel and the shell. 1cm is better, 2cm is a comfort fit (low performance)

Snowcovers seconded.
