Why do Korean dancers often slide their feet along the floor?

In traditional Korean dance, the practice of sliding the feet along the floor is a foundational movement characteristic of the art form. This specific gesture involves sliding each foot forward across the floor to conclude with an upturning of the toes. This movement is aesthetically significant because it echoes the distinct shape of the dancers' traditional slippers.1

This sliding motion, along with other signature movements such as the lifting and lowering of the shoulders, is a defining feature shared across most forms of Korean dance, including court, folk, shamanistic, Confucian, and Buddhist styles.1
