Replying to Wide boots needed?

I just recently bought some Tecnica Agent 80 ski boots online. Yes, i know you should never order boots online and go get fitted. Well, i did go to a local bootfitter to get my general size, but they didn't have any that were wide enough.
The Tecnica Agent 80s are a 102mm width. After wearing them for about 30+ minutes my top and side of my foot started to feel alittle sore (maybe because i havent wore ski boots in a while, but my foot started to tingle so i doubt that). Im currently in the process of ordering a half size bigger to see if this helps the problem.
1. If the half size bigger doesn't help that problem, what last year or this year boots would you suggest that are alittle wider than 102mm?
2. I also have the option to get the boots expanded by my local bootfitter, but will this result in the boot losing some of its intergity?
