Hirenkyaku

is a method in which Quincy use to travel quickly over short distances. It is basically the Quincy equivalent to the Shinigami's Shunpo, or the Arrancar's Sonído. Uryū Ishida implied that its speed is superior to Shunpo, though Mayuri Kurotsuchi's superior speed suggests that this is just a generalization.

Methods/Uses
To perform the technique, the user gathers spiritual particles under their feet and rides them to the desired location. Like the air-walking skill displayed by most Arrancar and Shinigami, it can also be used to hover or fly for long distances. Mayuri compliments Uryū on being able to use this technique at such a young age, suggesting that it is difficult to master. Hirenkyaku enables Quincies to keep up with, and overpower faster opponents depending on the user's skill. Uryū Ishida used it to easily defeat a seated Shinigami officer, a Números Arrancar, and even a former Espada in combat. However, there is apparently more use for the technique than simply moving quickly.

Platform Manifestation: Upon entering Hueco Mundo through the Garganta, Ichigo Kurosaki and Chad noticed that Uryū apparently had a platform of reishi under his feet. Ichigo and Sado had trouble controlling their reiatsu on the path they were given, while he used an instance of Hirenkyaku in order to make his own individual platform. Later on Uryū used the technique to elevate himself and Orihime Inoue through the hole Ulquiorra Cifer created in the artificial sky, and above the dome of Las Noches. He reveals that he only recently realized he could use the technique outside Garganta, and in Hueco Mundo itself, halfway to Las Noches. He also laments the fact that if he had known sooner, he might have been of some use on the battlefield. It is currently unknown if Ishida, or any other Quincy, can use this variation of Hirenkyaku outside of Hueco Mundo, within Soul Society, or the Living World.
