As a symbol, the heel represents the vulnerable part of an otherwise invulnerable person (Krishna, Achilles), and the part which kills the serpent.

Heels can also be symbols of:

Power and Authority: In many contexts, especially in Western culture, high heels are associated with power, authority, and confidence. This association stems from their historical connection with aristocracy and nobility, as well as their ability to elevate stature and change posture, giving the wearer a sense of dominance and control.

Femininity and Sexuality: Heels are often seen as symbols of femininity and sexuality. They accentuate the curves of the body, particularly the legs and buttocks, and are frequently worn in fashion and entertainment industries to enhance attractiveness and allure.

Social Status and Class: Historically, wearing heels was a sign of social status and wealth, as they were expensive and often worn by the upper class. Today, while heels are more accessible, they still carry connotations of elegance and sophistication, particularly in formal or upscale settings.

Empowerment and Liberation: Conversely, some feminists view heels as symbols of oppression, arguing that they enforce traditional gender norms and can be physically uncomfortable or restrictive. However, others see wearing heels as a choice and a form of empowerment, reclaiming them as symbols of self-expression and confidence.

Transformation and Escape: Heels can also symbolize transformation and escape from one's everyday self. They have the power to change one's posture, gait, and even personality, allowing the wearer to step into a different role or persona.
