I love these flats; I own them in two colors.  Fit is very standard for Hush Puppies.  If you own other Hush Puppies with this style sole, these will fit you that same way those do. I find that Hush Puppies are slightly wide.  While I'm a 9W in some styles, I'm a 9.5M in HP.

Very comfortable.  Would be great for business casual workplaces and travel.
