Of course, the printing method of the ganguerite ink 111 is not limited to the above-described and may be applied in various ways.

In addition, the elvan ink 111 is printed with respect to the entire area of the elvan printing layer 110, is printed in a dot matrix shape having a predetermined interval, or is limited to the sole contact surface corresponding to the sole of the foot as shown in FIG. The printed form is not limited thereto and may be modified in various ways.

According to the ganban stone printing layer 110 using the ganban stone powder as described above, there is an antibacterial effect on the removal of odor of the feet, harmful electromagnetic shielding, various harmful bacteria.

On the other hand, the ganganite printing layer 110 may be made of a first insulating film (112).

Here, the first insulating film 112 is a flexible sheet-like film, selected one of PP (Polypropylene; polypropylene), PVC (Polyvinyl chloride; polyvinyl chloride), PET (Polyethylene terephthalate; polyethylene terephthalate) It may be made of a material of.

Here, when the first insulating film 112 is a PET film made of the above-mentioned PET material, not only the tensile strength, the moisture resistance, the water resistance, the chemical resistance, and the insulation property are excellent, but the strains such as shrinkage and expansion due to temperature change are low. Since the thermal stability is excellent, the problem of being easily deformed by the external environment or a safety accident such as an electric shock can be prevented.

In addition, the PET film is hygienic because no plasticizer or stabilizer is added during processing, and there is an environmentally friendly advantage because no harmful substances are generated during incineration.

On the other hand, the first insulating film 112 of the above-described elvan printing layer 110 is defined to be clearly distinguished from the insulating film (second insulating film; 122) of the conductive ink printing layer 120 to be described below. It must be understood.

The conductive ink print layer 120 is a layer in which the conductive ink 121 is printed on an upper surface of the conductive ink print layer 120.

The conductive ink 121 may be an ink formed by dissolving an electrically conductive metal powder in a predetermined solvent such as a synthetic resin. The metal powder may include nickel (Ni) copper (Cu) silver (Ag) and gold (Au). ), Platinum (Pt), carbon (C) and the like.

In particular, the conductive ink connecting the both ends 123 may be printed in a zigzag form along the toe outer circumference.

In general, in cold weather, such as winter season, the capillary terminal of the human body contracts and blood flow is reduced or blocked. In cold conditions, the nose, ear, and ear, which are not directly related to life, increase the temperature in the center of the body. This is because less blood flows to the distal end of fingers and toes.

As described above, the distal end portion has a small blood vessel distribution, and as described above, when the weather is cold, the blood vessel contracts to cool faster than the body, and the risk of frostbite is increased.
