Empty Step

Empty Step (空歩, Kūho) is a skill born from  that acts as a simple, albeit difficult to maintain, extension of chakra control principles. By flowing wind release-aligned chakra into the sole's of one's feet, an individual is then able to add wind's property of weightlessness to their steps. In doing so, they are able to completely negate the impact of their steps upon the environment, almost entirely eliminating the vibrations associated with their movement and, accordingly, the noise they make. As such, this enables the Empty Step to be a powerful method of stealth. In addition, due to this technique causing the user to become fundamentally weightless when they are stepping on something, they are also capable of utilizing immaterial substances as footholds, such as vacuum shells in the air.

Through further concentration, one can apply this weightlessness to the entirety of the body. This action not only completely eliminates the sound from every single movement made, but additionally provides the body with an additional level of speed, due to not interacting with friction. Of course, the chakra control for a full-body maneuver is rather intensive, and other techniques can rarely be performed while using the technique in this way.
