another boot question

I know the whole boot thing has been done to death but I'm off to sauze in under a fortnight and want to make sure my shiney new boots don't kill my feet.
They've been fitted properly but I'm getting a feeling like my feet are being squashed across my toes- from the outside by my little toe(knuckle?). I do have very wide feet (like a hobbit as my OH loves to say) but I have wide boots (atomic b80s)as well. Should I go and get a big old bulge put in them or persevere and hope they pack out? Do they usually give much in this area?
Please help- i keep telling myself that boots shouldn't fit perfectly straight from the shop but I want comfortable boots for my holiday.
Any words of wisdom?

The best thing is if you can go to a indoor ski slope and ski, so yo can then go back to the fiter

Just my experience, but normally a slight squished feeling of toes, or of the foot, and heel generally go away as the liners pack in. Real aches, and pains around the foot (under/on top) don't normally get better, without some modification to the boot, or foot bed. If you don't have a slightly squished feeling for the first few days of skiing, it's a good indication that the boots will end up too big. Do you have some thin ski socks to wear until the liners pack in? As the liners packs in, you can switch to medium thickness socks.

Cheers for the advice. To be fair I have been wearing my thick socks so I'll try the thinner ones. I'd love to go and give the boots another go but I haven't got time now - off in 12 days!
Whatever happens my feet will just be glad that they're not being crammed into smelly rental boots!
