Stiletto heel

As a result of the overall sharpness of outline, it was customary for women to refer to the whole shoe as a "stiletto", not just the heel, via synecdoche (pars pro toto).

Although they faded from the scene after the Beatles era began, their popularity continued at street level, and women stubbornly refused to give them up even after they could no longer readily find them in the mainstream shops.

Subsequently, round-toe shoes with slightly thicker (sometimes cone-shaped) semi-stiletto heels, often very high in an attempt to convey slenderness were frequently worn at the office with wide-shouldered power suits.

The style survived through much of the 1980s but almost completely disappeared during the 1990s when professional and college-age women took to wearing shoes with thick, block heels.

[citation needed] Stilettos, like all similar high-heeled shoes, give the optical illusion of a longer, slimmer leg, a smaller foot, and overall greater height.

Stiletto heels can be found on almost every type of shoes, such as these ankle boots.
