Google "prostitute shoes", look at "images" not webpages, and you should understand.
Well, I get it now. But, I don't ever recall anyone ever wearing anything that extreme to Mass. The heels I'm used to seeing are a simple solid color with what seem to be shorter heels. I definitely would disaprove of wearing something like what I've just seen, plus I would hate to think of how one's stumps would feel having something like that on all day. Crazy...
