What makes a heeled boot an object of fetishism?

I'll admit I have a serious heel boot fetish, but what makes it so that people are turned on by it?What makes a heeled boot an object of fetishism?
First, let's begin at the bottom. The boot conforms to the shape of the woman's foot and toes, some reveal the shape of the ends of her toes, then continues up her foot clinging tightly showing the shape of her foot. It continues up showing the shape and contour of her leg all the way to the top of the boot. The heel adds a degree of fascination from the difficulty of walking with a heel and some daring to wear a heel. Knowing the the woman's leg and foot are inside adds a mystique. Hope this is a good answer, email if you wish.
