The finished shoes are installed on the finished shoe waterproof and tortuous resistance tester, and the tortuous part of the finished shoe is driven by the finished shoe waterproof and tortuous resistance tester, and the tortuous angle of the finished shoe matches its shoe shape and the fixed rate of the twisting machine are repeatedly twisted in the water tank where the finished shoe waterproof and twist resistance tester is equipped with a certain water depth and the water is dyed, until the finished shoe enters the water or reaches the pre-set number of twists. The waterproof and anti-penetration performance of the tested shoes under the tortuous condition is evaluated by the number of twists and turns, the amount of water entering the inside of the finished shoes or the size of the water penetration area of the finished shoes after completing the specified number of twists and turns. 【Relevant Standards】

Compliant: SATRA TM77, EN 20344 and other standards.
