What is cowboy boot spurs purpose?

Cowboy boot spurs are accessories worn by cowboys and horsemen/women that attach to the heel of cowboy boots. They consist of a small metal or brass wheel with spikes or points, and a strap that goes under the boot to keep it securely in place. The spurs are typically used to provide additional control to a horse, as well as to communicate with the animal through various kicking motions. The jingling sound made by the spurs is also considered an iconic element of cowboy culture. Today, spurs are often worn more for their aesthetic value than for functional use, and can be found in a variety of designs and styles to suit personal taste and fashion.
