Universal anti-skid sole

The invention provides a universal anti-skid sole comprising a sole body (1). The back surface of the sole body (1) is provided with a plurality of transverse or longitudinal anti-skid linear protrusions (2) with a separation distance of 5-15mm. The universal anti-skid sole is characterized in that the back surface of the sole body (1) is also provided with a plurality of anti-skid block-shaped protrusions (3) triangular or round in shape; the sole body (1) is peripherally provided with a wrapping reinforcing layer made of rubber. The back surface of the sole body is provided with the anti-skid block-shaped protrusions, so that the anti-skid coefficients in the transverse and longitudinal directions and in the other directions of the sole are relatively high, and the universal anti-skid sole has better anti-skid effects on various occasions.
