firstoff, check the sticky at the top of this forum to see how you should fit boots, but Im bored so Ill help you anyways.  well, they are entirely different boots neither of which would probably work for you.  Saying you have a wide foot means that your last will be wider, both supercharger series and the at have 98mm lasts.  Plus, the at is a super soft boot and doesnt even have a proper walk mode, just an adjustable spoiler.  If you're looking for an at boot, look into the new black diamonds, which have a 102 last or so, or the scarpa tornado, typhoon, etc which also have a wider footbed.  As far as real boots go, you could check out the dalbello p-series, I have the p10s personally and I love them, and there are wider lasts in other boot lines, rossignols tend to run a bit wider, spks are boats (like, 106 last or something rediculous)  Anyways, hope that points you ish in the right direction, go see a bootfitter, he'll put you in something that I've probably never heard of because there are a million boots out there.
