Footwear waterproofing test.
Tested both in the lab and real-world usage, NOVADRY®-equipped footwear guarantees optimum waterproofing and breathability. First, the shoe is immersed in water while internal air pressure is applied to check that no bubbles form on the surface of the footwear. Next, shoes are fitted to a mechanical arm that simulates walking and half immersed in water so we can test that the inside remains perfectly dry.
3 levels of waterproofing.
During the waterproofing test, we test 3 levels of waterproofing: 2000 flexes (around 2 hours of walking), 4000 flexes (around 4 hours of walking) and 8000 flexes (around 8 hours of walking). Of course, after this test or in use, the shoe regains its original waterproofing once dry.

Arpenaz 50 Warm Wtp Man boots are waterproof for 8000 flexes.
Measurement of the boots' thermal insulation.
It used to be impossible to tell the exact temperature down to which your shoes would protect you. Now it can be done: the temperature limits for use are shown on your Quechua shoes.
Using cold sensing tests while hiking and in the lab with a panel of customers, we measured the thermal resistance of our shoes while active and at rest. We take into account the differences in sensing cold between men and women.
