How do you heat mold and shape the shoes to your foot?

In order to heat mold your shoes, you can use an oven or a heat gun, according on whether you want to reshape them fully or only in specific areas. The oven option is recommended if you need to remold several areas of the shoe at the same time, such as the toe box, the heel pocket, or the general width, while the heat gun will be preferred for local heating on the desired spot only.

Once your shoes are heated, put them on and let them cool down while wearing them. Sit down during this process to prevent putting too much load on the sole while the material is too malleable. The shell sole hardens again, keeping the shape of your foot. With this method, the shoe can be widened or narrowed by 2-3 mm – which equals one width size. If you are using a heat gun, you may also mold the heated part with the backside of a screwdriver or pliers.
