I could only find navy blue (true navy) flats in this style- so am keeping them for that one dress that needs these shoes.  It runs narrow and is stiff- I had to push in the back of the shoe that cups the heel- to soften it a bit-  and would probably have to use heel guards not to get blisters.  Get 1/2 size bigger if you really want these- and if you have regular medium width feet.
