Glide step

The glide step or roll step is a form of movement used by marching bands to minimize upper body movement, enabling musicians to play their instruments and march without air-stream interruptions. Standardizing the style of marching also serves to add to the visual effect of a marching band. Sometimes special shoes are worn with a curved heel that facilitates rolling the foot. Glide stepping is used by many high school and college marching bands, and by many drum corps.
