Heat Moldable Insoles
Customization is always a desirable feature when purchasing a product. Heat Moldable Insoles allow you to customize the level of support by heating the arch support up. Usually it works by heating the insole up in a toaster over and then standing on them as they cool. To increase the arch support you can push up on the arch area while it cools. The "heat moldable insole" will then be permanently adjusted to your foot. Pretty much a custom orthotic at the price of a prefabricated insole.
