The Walking Simulator tests the waterproof performance of GORE-TEX® footwear. Test shoes are placed on flexible foot forms equipped with moisture sensors that are subject up to 200,000 steps in a water bath. If moisture enters the shoe, the testing stops and the sensor indicates the source of the leak. The shoe or boot must then be modified and submitted for another round of testing, to prove that they meet the rigorous GORE-TEX® footwear standards.
Boots filled with water are spun at high speeds. The resulting pressure forces water through even the smallest of holes to discover leaks. These tests are performed at every Gore certified factory.
The GORE-TEX® lining isn't the only component in footwear that ensures durable waterproofness. Materials used in the upper must also be non-wicking to prevent water from being transported into the shoe or boot over the GORE-TEX® lining. That's why we test all upper components from the shoe's leather and foam to the stitching and laces to ensure that the whole shoe or boot meets the waterproof performance standards.
