What is the true definition of a "Stiletto?"

Hello everyone,

I have been doing some research within the last few hours to determine, "What is the difference between a "high heel" and a "stiletto?"

Well here is what I have uncovered thus far,

A stiletto heel (amE: spike heel) is a long, thin heel 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. Stiletto heels may vary in length from 2.5 centimetres (1 inch) to 5 cm (2 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 shorter than 3 cm are called kitten heels.

I also uncovered the reason why most women prefer stilettos which I found to be very true in most cases. See below:

Stilettos give the optical illusion of a longer, slimmer leg, a smaller foot, and a greater overall height. They also alter the wearer's posture and gait, flexing the calf muscles, and making the bust and buttocks more prominent.

What do you women think? Is this pretty accurate or do you have a different take on it...let me know your thoughts...
