Alternatively, the present invention relates to a sanitary lining body of a closed footwear which exhibits a sterilizing effect or a bactericidal effect and a closeable footwear using the same.

[0002]

2. Description of the Related Art In general, footwear is worn for protection and trimming of the foot, and there are two types of footwear that expose the instep (open footwear) and those that wrap the foot (closed footwear). Yes,
Depending on the material of the closed footwear, leather shoes, rubber shoes, cloth shoes,
Zuk shoes, chemical shoes (mainly vinyl shoes), sabot
(Wooden shoes), etc.

In particular, in the case of closed-type footwear, since the foot is wrapped up, moisture such as sweat secreted from the foot is likely to be retained inside the footwear, and various bacteria may propagate on the inner surface of the footwear to give off a strange odor. There is a problem that the wearer may get athlete's foot.

Conventionally, in order to solve such a problem, for example, a moisture absorbent, an antibacterial agent, a bactericidal agent, a fungicide, a deodorant, a deodorant, etc. is inserted into an insole which is inserted along the insole of footwear. Means for supporting one or more of the sanitizers described above are taken.
