The bottom layer is made from Poron 4000 Performance grade urethane. The material is blue in colour and designed to reduce impact to the feet and joints by providing advanced shock absorption and increased cushioning support.

The top layer of this dual material is a clear gel panel, which acts like human fatty tissue to cushion bony protrusions and pressure sensitive skin. The gel displaces weight evenly thus preventing the focus of pressure on one area alone.

Poron Gel is also coated with an ionic silver antimicrobial surface layer. This provides the material with antibacterial, antifungal and deodorising properties.
