Referring to FIGS. 1-4, an antislip device comprises a block 60 including a bolt 61 for threading 15 and securing to the screw hole 11 of the typical shoe 10 and including one or more spikes 62. The block 60 may include four spikes 62 (FIGS. 1-5) , one spike 62 (FIGS. 6-9), or even no spike 62 (FIGS. 10, 11). The block 60 is made of relatively harder material, such as 20 metal or plastic material for forming the bolt 61 that is strong enough to be solidly secured to the shoe 10. It is preferable that the spikes 62 each includes an end portion having a square cross section and each includes a cylindrical base portion 67 having a greater 25 outer diameter than that of the body of the spikes 62 for increasing the strength of the spikes 62. The decreased length of the square end portions of the spikes 62 may be used for determining whether the spikes 62 have been worn out or not.

The antislip, device further includes a peripheral skirt 70 provided around or extended radially outwardly 05 from the outer peripheral portion of the block 60 and secured to the outer peripheral portion of the block 60 by such as the molding or mold injection processes. The peripheral skirt 70 is made of such as the rubber materials which has a strength less than that of the 10 block 60 but has a resilience greater than that of the block 60, such that the rubber peripheral skirt 70 may provide a great resilience to the antislip device. The block 60 may be formed in one mold device with the harder or stronger plastic material, and the rubber 15 peripheral skirt 70 may then be formed with another mold device before the plastic material for forming the block 60 is hardened or cured, such that the plastic block 60 and the rubber peripheral skirt 70 may be formed and secured together with the molding process 20 without any further adhesive materials or welding processes. The block 60 and the peripheral skirt 70 may be formed with different colors or with transparent or semi-transparent materials.

The peripheral skirt 70 includes one or more 25 spikes 71 extended downward therefrom. It is preferable that the spikes 71 each includes a base portion 73 having a square or frustum- shaped cross section (FIGS.

2-5, and 10, 11), and each includes a cylindrical end portion 74 having a smaller outer diameter than that of the base portion 73 of the spikes 71 such that the strength of the spikes 71 may be increased. The 05 decreased length of the end portions 74 of the spikes 71 may be used for determining whether the spikes 71 have been worn out or not and whether the antislip device is required to be changed or not.

The peripheral skirt 70 may further include one or 10 more air cushioning devices 80 formed above the spikes 71 respectively and having a chamber 82 formed therein or defined with a cup member 81. The cup member 81 may be a frustum-shape (FIG. 2), or a conic shape (FIGS.

12, 13), or a rectangular shape (FIG. 14) or the like, 15 and may include one or more reinforcing ribs 84 (FIG. 12) provided thereon.
