Description

{Non-slip Sole for Shoes}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shoe sole for preventing slippage, and more particularly, to a shoe sole for preventing slippage in walking in places where a lot of water, rock, ice and the like are present.

In general, shoes are worn on the feet of a person to protect the feet of a person during walking, and include an upper which forms an outer shape, an insole which forms the bottom of the upper, and a middle and sole provided on the bottom of the insole.

The sole is generally made of a rubber material for absorbing an impact to a part contacting the ground during walking, has a plurality of slip prevention grooves formed on a lower surface contacting with the ground to prevent slipping during walking, Respectively.

However, the slip prevention protrusions or the slip prevention grooves formed in the sole are formed in a simple shape that is protruded or worn out in only one direction, so that the slip prevention effect is not significant.

Therefore, there is a problem that pedestrians are seriously injured in an accident that slips while walking when walking on a place with lots of water, rocks, ice, etc., such as a mountainous area rather than a general plain area.

In the case of combat boots worn by soldiers, there are many cases where people walk in mountain valleys, rocks in valleys, places where snow or ice piled up in winter are piled up. In this case, accidents involving soldiers are frequently caused by slipping accidents, Which is a cause of deterioration.

Particularly, in the case of mountain walking in the winter, there are many places where snow and ice are formed. Thus, a steel spike such as Aizen is worn on shoes to prevent slipping during walking. In this case, a steel spike is uncomfortable for walking, There is a problem in that slippage is effectively prevented only in the ice road and slippage in rocks of the valleys is not effectively prevented.

In addition, the above-mentioned Eizen is inconvenient to be worn only on the snowy or ice road in order to solve the inconvenience at the time of walking, and there is an inconvenience that it must be removed from the other terrain and it is inconvenient to carry it separately.
