I wear an 11 wide. Totally sucks. I have found that Tom's fit my fat foot. They're a little tight when I first get them, but they stretch out. I found a pair of flats at walmart that were 11 wide. Mostly I wear sandals/flip flops, so the wideness doesn't matter. I used to go to a shoe store in the town over from me and they would let me look at their size 11 wall. They used to think it was so funny that I'd just ask to go back there. Took the hassle out of me wandering around asking if things came in my size. I used to wear Birkenstocks all the time, but the pair I have now are busted and I don't have money to replace them.

I feel sorry for my sister-in-law, she wears a 14, but she's also 6'3". My husband and his brother have it bad too. My husband wears an 18 and his brother wears a 20. Try finding those kind of sizes.
