Adhesive foam discoloration
Our professional latex is a natural product that is subject to natural processes and variations in the dye. This often happens when washing for the first time due to contact with minerals in the water or cleaning products (soap, shampoo etc.).
This discolouration will go away after a while, and become bleached by sunlight.
Discolouration is a normal process and does not affect the grip or durability of the surface.
