PURPOSE: An insole is provided to secure a softer elasticity than a cushion formed with materials like urethane by using an air pressure, and to facilitate a walk of a wearer. CONSTITUTION: An insole comprises the following: an air pack(11) formed by overlapping two sheets, and fusing the two sheets with high frequency waves to form the air pack into an insole shape; welding lines(12a,12b,12c) located on the top and the bottom of the air pack; and an air bank filled with air while being formed in between the welding lines for providing the cushion feeling to a user by producing the elasticity. The welding lines on the front side of the air pack are transversely formed. The welding lines on the center are longitudinally formed. |
