Stilettos?

A stiletto heel (AmE: spike heel) is a long, thin heel often found on some boots and shoes, usually for women. It is named after the stiletto dagger, the phrase being first recorded in the early 1930s.^[1] Stiletto heels may vary in length from 2.5 centimetres (1 inch) to 25 cm (10 inches) or more if a platform sole is used, and are sometimes defined as having a diameter at the ground of less than 1 cm (slightly less than half an inch). Stiletto-style heels 5 cm or shorter are called kitten heels. Not all high slim heels merit the description stiletto. The extremely slender and original Italian-style stiletto heels of the late 1950s and very early 1960s were no more than 5mm in diameter for much of their length, although the heel sometimes flared out a little at the top-piece (tip). After their demise in the mid-late 1960s, such slender heels were difficult to find until recently due to changes in the way heels were mass-produced. A real stiletto heel usually has a stem of solid steel or alloy. The more common method of mass-producing high shoe heels, i.e. moulded plastic with an internal metal tube for reinforcement, does not usually achieve the true stiletto shape.
