This is a thermoplastic material often a hot-melt adhesive sheet made from a combination of materials like polyester fabric and EVA glue. It's a key component for adding structure and shape to a shoe's front (the toe) and back (the heel).
- Key characteristics:
- High Elasticity and Resilience: The most defining feature. This material has an excellent "ping pong effect," meaning it can be bent compressed or deformed and will spring back to its original shape. This is crucial for maintaining the shoe's form over time preventing it from getting "crushed" or misshapen.
It often has a self-adhesive backing making it easy to handle for shoemaking. - Lightweight:
- It adds structure without adding significant weight which is important for sports and casual shoes.
- Strong Viscosity and Adhesion:
- It is typically a "hot-melt" material which means it becomes pliable and bonds strongly with other materials (like the shoe's upper) when heated. This ensures a secure and lasting hold.

: It is designed to be tear-resistant wear-resistant and flexible which contributes to the longevity and comfort of the shoe.
Ping pong sheets are available in various thicknesses and hardness levels to suit different types of shoes, from soft and flexible casual shoes to more rigid and supportive safety or sports footwear.
