My feet are wide but not super-wide. I have Specialized standard width road shoes and they are very comfortable for me.
Important to remember that there is more to a shoe fit than width. Shoes are made on a last (a foot shaped form) and there are many different lasts with different attributes. Heel width, toe box depth, instep height, etc. Some companies may make all their shoes using the same one and others may use different lasts for different models.
