Stripper platforms
From Voyeurweb's Wiki
Stripper platforms: Extreme platforms very often worn by strippers and dancers sometimes known as dancer's shoes. Stripper platforms are also popular for fetish reasons.
The plateau (platform) of these shoes are 1 inch and higher, and the toe to heel rise is usually 5 inches, making the overall height of the shoe 6 inches or more. These platforms are often made of transparent acrylic, which can help mask the bulky and dominating structure of the shoe.
According to Igor, stripper platforms are the ugliest shoes a women can wear.
Igor: "For some reason looking at a girl wearing platforms makes my penis shrink rapidly." (ref: VW Encyclopedia)
