航鱼靴 are boots that allow the user to run super fast. You can get this item from 木匣s and 铁匣s. When the user is running fast they get water particles coming out of their backs. After a build-up, the user can run up to a maximum speed of 31 mph without other movement accessories. 赫尔墨斯靴, 航鱼靴 and 疾风雪靴 are functionally identical, and are interchangeable when crafting 幽灵靴.
