Product Advantages

Hard wearing outsoles:

  1. Density range 1.2 down to 0.7 kg/m3 depending on design
  2. Rubber-like grip and feel
  3. Non-floor marking
  4. Excellent abrasion resistance
  5. Good surface definition
  6. Improved sole flexibility (Bata belt / Bennewardt).

Lightweight comfortable midsole:

  1. Better cushioning
  2. Multiple colors possible (fashion oriented).

Productivity:

Compatible with standard polyurethane injection and casting machines; cumbersome stick on processes can be avoided.
