Glissades are a type of gliding dance step that involve sliding one foot along the floor while the other remains in place. This type of step is often used in ballet, jazz, and modern dance. It is also sometimes used in ballroom dancing. Glissades can be performed in various directions, including forward, backward, and sideways. They can also be done in a circular motion. Glissades are an important part of many dance routines and can add a graceful and dynamic element to a performance.
