Glide step

Glide 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 marching bands, college marching bands, and by many Drum Corps. Glide stepping is sometimes also known as "roll stepping".
