I have wide forefeet and I'm really liking the latest range of "wide fit" Fizik shoes. I have both the mid-range Overcurve R4 Wide and the high-end Infinito Carbon 2 Wide. Both are very comfortable and I use them with Specialized Green (high arch) insoles.
For ref my bare foot length is 281, width 112 and I have these shoes in size 44.5. You would likely be 45.5/46.0 and borderline standard/wide fit. I find that the heels are relatively narrow, which suits my feet.
