Kinky boots are boots with extreme characteristics which are intened to present a dramatic sexy appearance, such as by a prostitute or dominatrix. Extreme characteristics might include very high heels, thigh- or crotch-high length, or unusual colors or materials. They can be related to boot fetishism, a kind of shoe fetishism which thus make them a form of fetish clothing. The term is ambiguous, since what can be considered kinky by some can be seen as elegant fashion by others.
