Abstract
An antibacterial cupric-ion-fiber corrective shoe-pad and a manufacturing method thereof are disclosed. The shoe-pad is manufactured by staking a cupric-ion-fiber face layer, a shock-absorbing layer, a support layer, and an antibacterial and anti-slip layer in order, and laminating the layers into a laminate in a mold through hot pressing, wherein different temperatures are applied to the shoe-pad during the hot pressing to form support zones as well as a heel enclosure and its extension segment that enclose rear and outer sides of the shoe-pad, thereby providing a human foot with protective and supportive effects such as shock absorption and pressure distribution. When the shoe-pad is placed into a shoe, the cupric-ion-fiber face layer when contacting the human foot provides long-lasting antibacterial and anti-odor effects, and the bottommost antibacterial and anti-slip layer prevents the shoe-pad from undesirably shifting in the shoe, thereby enhancing user comfort.
