There are many styles of insoles. Some insoles have shells in them. What’s the purpose of doing this?
Some insoles have shells to provide additional support, structure, and stability to the foot. The shells are typically made of hard, rigid material, such as plastic or fiberglass, and they cover the bottom or the arch area of the insole.
The shell helps distribute weight and pressure more evenly across the foot, reducing stress on certain areas and alleviating discomfort or pain. It can also help correct foot alignment and provide stability for individuals with issues like overpronation (excessive inward rolling of the foot) or supination (outward rolling of the foot).
Overall, the shell insoles offer enhanced support, cushioning, and stability for individuals with specific foot conditions or who engage in high-impact activities that require extra foot support.
We also have heat moldable PP shells, TPU shells, etc., which can be used in heat moldable insoles. If you need anything, you can contact us.
