Abstract: The present application relates to a rotatable anti-slip device and an all-terrain anti-slip sole, wherein the anti-slip mechanism can turn over relative to the mounting seat by providing a rotation part. Specifically, by providing a sphere, the rotating shaft can rotate along the spherical surface. At the same time, the rotating shaft is arranged between the sphere and the friction part, and the rotating shaft can limit the rotation direction, so that the friction part can be turned over along the rotating shaft. The friction part has a first friction surface and a second friction surface. Users can adjust the friction part according to different terrains to meet the anti-slip needs of different terrains, which effectively improves the anti-slip effect on different terrains. Additionally, the anti-slip device can be easily and conveniently replaced, and the anti-slip function of the shoes will not be lost due to accidents or damage.
