Gliding

Gliding is a method of magical locomotion where the beast, being or spirit moves at a walking rate slightly above the ground, but without using feet. It is similar to Levitation or Flying, but distance above the ground is limited.

DESCRIPTION
Several magical beings are seen to glide across a solid surface. This seems to be something other than a graceful walk to reduce or eliminate the normal jerky motions associated with walking. However, as witches and wizards often wear floor-length robes that cover their feet, grace in walking cannot be ruled out.

Not much is known about this magic; for instance whether one can glide where one could not normally walk, such as across a gap in the ground, or over water. If the latter is the case, then this would be another possible means for Hagrid to have reached the Hut-on-the-Rock, which was in the sea.

EXAMPLES
Professor Trelawney on Christmas Day, 1993, entered the Great Hall and glided toward the table seating twelve.

Lord Voldemort upon entering the Hogwarts grounds, glided alongside Professor Snape before sending him away so he can open Dumbledore's Tomb in private.
