The present invention relates to a customized shoe insole and to a customized sandal. More particularly, a customized shoe insole comprises a surface layer, an upper layer unit, a heating sheet including a heating portion and an electrode portion, a thermoplastic resin sheet, and a power supply terminal. The heating sheet includes the heating portion, which has a heating circuit formed by printing a conductive paint that contains fine powder of one or a mixture of two or more elements selected from silver (Ag), carbon (C), and copper (Cu) on a polyethylene (PE), polyethyleneterephthalate (PET), polycarbonate (PC) or polyimide (PI) resin film, and the electrode portion which is precisely connected to the power supply terminal. The heating circuit is repeatedly arranged by once or twice or more so as to form a zigzag shape with predetermined intervals thereafter, and repeatedly arranged again by once or twice or more so as to form a heating circuit. At least one of the intervals forms a cutting line while maintaining a predetermined distance from the heating circuit inwardly from an outer surface of the heating sheet such that the heating sheet can tightly contact a foot-shaped thermoplastic resin sheet having a curvature. Thus, the customized shoe insole can be made to completely fit the shape and characteristics of the foot of the wearer while maintaining a predetermined molding temperature by the heating sheet. Therefore, a customized sandal can be produced with which the customized shoe insole is integrally formed so as to maximize wearing comfort and minimize fatigue. |

1. A customized shoe insole being characterized in that and includes:
a surface layer including a fiber material being contacted with the sole of the wearer's foot; an upper layer unit being stacked under said surface layer and for absorbing the impact while walking; a heating sheet being stacked under said upper layer unit and including a heating portion and an electrode portion; a thermoplastic resin sheet being stacked under said heating sheet and capable of molding thereof by the heat generated in said heating sheet; and a power supply terminal capable of supplying an AC or a DC to said heating sheet, wherein said heating sheet includes:
a heating portion comprising a heating circuit, wherein said heating circuit is formed by printing with a conductive paint containing fine powder of one or a mixture of two or more elements selected from silver (Ag), carbon (C) or copper (Cu) on a polyethylene (PE), polyethylene terephthalate (PET), polycarbonate (PC) or polyimide (PI) resin film; andan electrode portion being precisely connected to said heating circuit of said heating portion and the power supply terminal, wherein
said heating circuit is repeatedly arranged by once or twice or more so as to form a zigzag shape with predetermined intervals thereafter, and repeatedly arranged again by once or twice or more so as to form a heating circuit; a cutting line is formed while maintaining at least more than one of said predetermined distance from the heating circuit inwardly from an outer surface of the heating sheet such that said heating sheet is tightly in contact with a foot-shaped thermoplastic resin sheet having a curvature. |
