Abstract: A sole slide-proof device comprises a sole below a shoe body; and a plurality of soft suckers installed below the sole; the sucker being a tapered disk body; and a lower side of the disk body being a concave groove; and an opening of the groove being at a lower side of the sucker. Moreover, a plurality of blocks can be mounted between the sole and the suckers. The suckers have an effect of absorbing the sole to ground so as to have the effect of slide-proof, heat-isolation, and vibration-absorption.
