Spike heels, also known as stilettos (9 letters), are a type of high-heeled shoe with a long, thin, and pointed heel. They are typically worn by women for formal occasions or to make a fashion statement. The heel is usually between 2 and 5 inches in height and the toe area is often pointed or almond-shaped. Spike heels are often made of leather or synthetic materials and can be found in a variety of colors and styles.
