At what point is a heel considered "stiletto?"

Glad you asked because the stiletto heel, which is usually 2" or more, is my favorite kind! First, let's be clear that "stiletto" refers to an entire style of the heel, not just the height. Anything above two inches would be considered stiletto, though most of the time, we seem to see stiletto heels stretching it out to a good four inches!

There are plenty of heels out there that tower at four to five inches, but the stiletto also refers to the shape. The name actually comes from the stiletto dagger, which is very narrow before it comes to its sharp point, thus the stiletto heel itself is quite narrow, coming to a point on the ground that is 1 cm in diameter or less.
