Disclosed are a universal slip-reduction supporting leg and a walking stick. The universal slip-reduction supporting leg comprises a supporting base (1) and a connecting piece (2) arranged on the supporting base (1), wherein the supporting base (1) has a supporting bottom surface (10), the upper surface of the supporting base (1) is provided with a spherical concave portion (11), the bottom of the connecting piece (2) is provided with a spherical connecting portion (21) corresponding to the spherical concave portion (11), and the spherical connecting portion (21) is arranged in the spherical concave portion (11) to form a rotatable movable connection. In the universal slip-reduction supporting leg, the supporting base (1) forms a rotatable movable connection with the connecting piece (2). Therefore, whether a connected external main body is in a vertical state or in an inclined state, the supporting bottom surface (10) of the universal slip-reduction supporting leg at the lower part can always keep planar parallel contact with the ground or other supporting surfaces, namely, the maximization of the contact area between the supporting base (1) and the supporting surface is always guaranteed, thereby realizing the effects of slip reduction and slip prevention. The present invention has a simple structure, and the use stability of the walking stick is enhanced, so that the use security can be improved.Linvention concerne un pied de support universel à réduction de glissement et une canne.
