Yeah, the three brands I think of when I think wide bike shoes are Specialized, Lake and Northwave.

I wear a small size (38) so I couldn't even try the Sidi Mega's. Up until last year, I was fine wearing Specialized shoes in the men's versions (they make them small enough for me if I order online) but after my foot surgery, even those were too narrow. Now I wear Northwave but I had to order them online (I picked out 4 pair and returned the three that didn't work).
