Description

  The present invention relates to a footwear sole, and more particularly to a ventilation sole in which a structure capable of air inflow and outflow and a pumping action is formed in the footwear sole so that a pumping action of air inside and outside the footwear naturally occurs by walking.

  In general, since footwear is manufactured using leather or synthetic resin with poor air permeability, when worn for a long time, ventilation with the outside is not ensured and the inside of the footwear becomes hot. Therefore, moisture is generated by sweat, and at the same time, mold or the like inhabits, causing foot odor or athlete's foot.

  In order to solve the problems described above, conventionally, footwear capable of various forms of ventilation has been introduced.

  Some of them are briefly introduced below.

  Korean Registered Utility Model Publication No. 20-144133 discloses an air circulation structure of an outsole. According to this cited document, a pump member is separately installed and the outside air is circulated to the outsole side. However, this structure is complicated, and natural air circulation is impossible, and external foreign matter is not possible. Has the disadvantage of inflow without permission.

  Korean Utility Model Publication No. 20-218227 discloses a shoe cushion having a plurality of vent holes. This is a structure in which air is circulated to the lower part of the outsole using an air tube, but this is also complicated in structure, and it is impossible to circulate air naturally, and there is a disadvantage that external foreign matter flows in without permission. is there.

  Korean Registered Utility Model Publication No. 20-229738 discloses footwear provided with a ventilation device. According to this cited document, a cushion layer and a check valve means for performing a pump function are provided, and air is circulated to the lower part of the outsole.
