For a product to bear the Superfit "Waterproof" seal, it must meet quality standards that are among the most stringent of the footwear industry.
All construction materials are waterproof.
A waterproof layer is sewn inside the boot to keep feet dry. The layer is manufactured in the shape of shoe, and tape is applied to its seams with waterproof glue for sealing that prevents any infiltration of water.
Each waterproof layer is tested before being used in the manufacturing of boots. Throughout the production chain, pairs of boots are sampled at random to be tested in the laboratory for their waterproof sealing.
The quality standard of Superfit are in the among the highest in the footwear industry.
