The main materials used in heat moldable insoles are:
1. EVA (Ethylene-vinyl acetate)
This is a lightweight and flexible foam material that provides cushioning and support to the feet.
2. Polyurethane (PU) foam
PU foam is another common material used for heat moldable insoles. It offers excellent shock absorption, and durability, and can be easily molded to conform to the shape of the foot.
3. Thermoplastic elastomers (TPE)
TPE materials are known for their elasticity and flexibility. They allow the insole to be heated and shaped according to an individual’s foot contours, providing customized support.
4. Poron
Poron is a high-performance cellular urethane material that provides superior shock absorption and energy return properties. It helps reduce impact on joints during walking or running.
5. Gel inserts
Some heat moldable insoles may include gel inserts or cushions at specific pressure points of the foot for enhanced comfort and support.
These materials are designed to be heated using specialized equipment so they can become pliable enough to mold directly onto an individual’s feet, creating a custom fit that improves comfort, stability, and alignment while walking or standing.
