Chick-books love shoes and if you're going to talk shoe-talk you kind of deserve your blah cover. If your book presents "cozy" female friends "weathering crises" together then you've also earned the sandals and Adirondack chair treatment. And if one of your characters dares to admit that she likes "a pink cover featuring a pair of glossy high-heeled shoes," you most definitely should have flowers and pastel shades on your dust jacket.
