Basically you're asking for anything that fits this description:
b. Females. Plain black, brown or white dress pumps made of smooth leather or synthetic leather, with closed heels and toes. Heels shall be no higher than approximately 2-5/8 inches nor less than approximately 5/8 inch measured from the forward edge, and no wider than approximately 1-3/4 inches at the base. Sole shall be no thicker than approximately 1/4 inch. Wedge heels are not authorized.
Are they that difficult to find? Since the description for men's shoes only mention oxfords, I'm going to sport some Oxford lacing as opposed to the standard blucher when I next have to wear the dinner jacket.
