The paws were filled with foam with increased density, i.e. polyurethane foam, i.e. foamed with foam, which has very good shock absorption and resistance to deformation.
In their front part a gel insert was used to ensure excellent shock absorption. The combination of these 2 materials makes the discs are lightweight and at the same time perfectly absorb the impact.
The shields are made of PU ensuring resistance to damage and high comfort of use.
