Thick-soled, usually platform-heeled sandals or shoes. Some heels can be as high as 8 inches...those are too uncomfortable for normal life though. 4 or 4.5 inch-ones are cool. I have 2 pairs of more-or-less pornstar shoes, but, just for the record, all my shoes with heels are thick.
I wear pornstar shoes to show my individuality and to pay tribute to 1970s punk culture (which was close to porn)...I even wore a pair to my prom banquet, and no one gave a shit.
