I have SIDIs and my husband has Specialized raod shoes. We both love them. Each fit a little differently and sizing is different from street shoes, so
go to a store and try them both on if you can. I have a narrow heal, and SIDIs fit me best in this regard. They also have a narrow toe boz, so keep that in mind of you have wide feet. They make a "mega" for wide feet, but I don't remember if they come in women's. Even SIDIs lower end models are nice and will last a long time.
