A shoe having natural cooling and heating system

The present invention relates to a shoe having a natural circulation cooling / warming system, and more particularly, to lower the internal temperature of the shoe when the external temperature is high, such as in the summer, to cool the wearer's foot and to obtain a comfortable feeling. The present invention relates to a shoe structure having a natural circulation cooling / warming system which can prevent breeding in advance and prevents frostbite by providing a heating means in winter to prevent frostbite.

The shoe is to protect the wearer's foot. In winter, the foot is cold due to the low outside temperature, and in the summer, the inside temperature of the shoe is significantly increased due to the high outside temperature.

When the shoes are cold due to low outside temperature such as winter season, there is less problem of athlete's foot causing skin disease, but when outside temperature is high like summer season, it causes various problems due to poor ventilation. .

As described above, in the summer, when the outside temperature is high, a lot of sweat is generated by increasing the temperature inside the shoe, and thus, the inside of the shoe is always in a wet state, thereby providing a cause such as a deterioration of foot health. When a lot of sweat occurs, the sweat temporarily accumulates in the shoes and socks, and when worn for a long time, a considerable amount of sweat accumulates in the shoes, causing severe odors, and becoming a breeding ground for various molds and bacteria, such as eczema and athlete's foot. Problems such as causing skin diseases are occurring.

In addition, even if it is not serious like athlete's foot, those who work in frozen warehouses or ski resorts or those who have to work on ice and snow outside even in cold weather under special circumstances like soldiers have frostbite risk in winter. Practically many soldiers are suffering from statues.

In order to solve the above problems, the shoe structure may be provided in such a way that the upper of the shoe is formed in a mesh shape so as to be worn when the external temperature is high, such as summer, or a plurality of vent holes are formed on one side of the shoe. Even if a vent is formed in sneakers, sneakers or work shoes, the vent is blocked by the user's foot in actual use, and the air cannot circulate inside the shoe. The sweat accumulates in the shoe, causing severe odors and suffering from skin diseases such as eczema and athlete's foot due to various fungal growths.
