Therefore, the chain 50 and the connecting chain 52 are connected to the connecting portion 70 having a clearance to the position of the connecting portion of the front plate 30 and the rear plate 40, even if the force is applied in the eccentric direction during walking 70 is free and the fastening band 60 is to prevent the phenomenon of twisting or peeling in advance.

In addition, even when walking a variety of terrain, the fastening band 60 can always maintain a stable wearing state, allowing the play even when the position of the front plate 30 and the rear plate 40 located on the bottom of the hiking boots are out of position when walking Can be slowly returned to its normal position.

Therefore, merchandise and reliability are improved.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

Figure 1 is a perspective view of the chain-type eisen wearer of the present invention as seen from the bottom.

Figure 2 is a bottom view showing the expanded state of the eigen of the present invention.

Figure 3 is a partial cutaway in a state in which the present inventors chain-type eisen worn on hiking boots are shown in cross-sectional view.

Figure 4 is an enlarged view of the bottom surface showing the main operation state of the present invention.
