How can I be sure my boots are 100% waterproof?
We made sure that your boots are waterproof by conducting laboratory tests to simulate walking with the boots half-submerged in water. We also conducted field tests to measure wear and ageing. During the waterproofing test, we test 3 levels of waterproofing: 2,000 flexes (approx. 4 km walk), 4,000 flexes (approx. 8 km walk) and 8,000 flexes (approx. 16 km walk). Your boots were tested to 4000 flexes, which is equivalent to 4 km of walking.
