I also have wide feet and used to wear Specialized in the men's versions for extra width in the toe box. Not something I could do in running shoes or my heels would slip out (less of an issue in a cycling shoe, I think - to Oak's point).

After my foot surgery, even my Specialized shoes were too narrow on my right foot causing instant pain. I ordered a pair of Northwave's from amazon (the pair I found that had the most reviews mentioning a wide toe box!) and they work pretty well.

I am waiting for the day when cycling shoe companies join the growing trend in running shoes by making ergonomically correct shoes! Who has pointed toes??
