Replying to Footbeds and Boots

Now this past month i got a new pair of boots for this season, as my old pair was fitted wrong and packed out and ended up being too big/ lots of other problems. Now ive been wearing them around the house and such to try to break them in before the season begins and there are just a few points wheres theres some pressure. Not really pain, but a little discomfort. And my big toe is a little tight. But here is where my question begins. I still have yet to get a pair of footbeds for my boots.

The place i bought them at didnt have footbeds in yet and ive been calling every week to see if they have gotten them in yet, and still nothing. I plan on going up to killington here soon and im positive they have a bootfitter at the base of the mountain or close. Should i just wait now and get footbeds from there when i head up, or is that taking too big of a risk if they dont have them in stock or some other issue. I just dont want to begin skiing this year without having a footbed in my boots and having them fitted right. My feet are asking for mercy this year haha.

One more, If the shop i go to in VT does not have the make of boot in their store, will they still do work on it? Like i had a dabello or atomic boot and they didnt sell those boots there, would the shop still do work on them?

Thanks in advance everyone. Could really use some NS wisdom here.
