A bit of both. Boots with dresses/skirts and such (as long as they have at least a 3 inch heel). Shoes as well for warm days, or long dresses, and pants, and also heeled by at least 3 inches. And occasionally tennis shoes. :P
No reason why exactly, other than that I love all types of shoes. But I *prefer* shoes with heels because I'm short at only 4'10 1/2. Heeled boots are classy, and if you get the right style can be a bit edgy as well.
