A perfect example of this system of monitoring the aristocracy is red heels on shoes. Louis declared that only those in the royal favor were allowed the privilege of having red heels on their shoes, allowing everyone to show off when they were in favor. Red heels was like sitting at the popular kids table in school, only the very coolest kids could wear them.

Suddenly, if you fell out of the royal favor, everyone would know. It's bad enough to be out of the royal favor, it's even worse when you have to advertise it to the world. It was the perfect method for controlling a once unruly upper class. Aristocrats behaved themselves and they didn't have to face the shame of not having red heels on their shoes.
Louis XIV and his family, c. 1715-1720
Notice Louis' grandson, dressed in red and standing to the right. While Louis and his son (standing to the left) are wearing red heels on their shoes, his grandson is not, signaling that he was out of favor around the time this picture was created.
The connection between red heels and the monarchy lasted well past Louis XIV. In 1780 a pamphlet attacking Marie Antoinette was released, entitled Portefeuille d'un talon rouge (the wallet of a red heel). Red heels had become just one more symbol of the absolutist system that was beginning to tear the country apart.
Shoes by Christian Louboutin
Here are some fierce Christian Louboutin shoes. All Louboutin shoes have the inside of the heels and the sole painted red, perhaps a nod to the flashy cabaret girls that originally inspired the designer. For me, I always connect these modern red heels with Louis XIV. After all, wearing a pair of Louboutin shoes expresses the same ideals as wearing red heels in the 17th and 18th centuries- wealth, privilege, and a place in the choicest of social circles.
