OK, this is a report on the Sidi Dominator mtb shoes; I got for road riding after the recommendations here, and because my old shimanos were wearing out. I have had surgery for bunions on both feet, and they still tend to be on the wide side (thank goodness for living in a place where Birks and danskos are professional wear!) I found them on sale, and got men's because experience shows that these usually fit me better. The salesperson said that they men's are made a bit differently (I think with respect to the arch), but I wear stiff orthotics so that doesn't make much of a difference.
They are definitely wide enough, and the adjustments are great--one foot is wider and I love being able to make the adjustment. They are soft leather and really comfortable, and the soft leather will conform to my feet. Also nice and stiff, stiffer than my previous ones, which is very nice on standing climbs, yet pretty walkable and not slippery. Also pretty cute and do not make my feet look big. So, while they are pricey, they will last a long time, are really comfortable and work very well, at least that is my justification and I'm sticking with it.
It is finally lovely here, breezy but clear, lots of whitecaps and sailboats out on the ocean, in the low 60s, and tailwind coming back, yea.
