When a heat moldable insole is heated, it becomes soft and pliable, allowing for customization according to individual needs. Typically, before heating, the insole is placed in an oven or using a specialized heating device. Once it reaches the appropriate temperature, the insole becomes pliable and can be shaped by stepping on it with your foot to conform to the shape of your foot.
However, it’s worth noting that some thermoplastic insoles may revert to their original shape after cooling. This is because thermoplastic materials have memory effect, where they attempt to return to their initial shape during the cooling process. While most thermoplastic insoles maintain shape stability for a period of time after shaping, over time and with extended use, they may gradually lose their ability to retain the molded shape. Additionally, external forces can also cause deformation of the thermoplastic insole.
However, Ideastep brand heat moldable insoles are made from materials that are less prone to deformation. Once the insole is heated and molded, it can maintain its shape for an extended period of time.
