Footwear waterproofing test
These boots, which are laboratory and field tested, provide optimum waterproofing and breathability. The boots are initially immersed in water with pressurised air inside to check for bubbles on the surface of the boot. Next, the boots are fitted to a mechanical arm that simulates walking, half immersed in water so we can test that the inside remains perfectly dry.
3 levels of waterproofing.
During the waterproofing tests, we test 3 levels of waterproofing, with 2000 flexes (approx. equivalent to a 4 km walk), 4000 flexes (approx. equivalent to an 8 km walk) and 8000 flexes (approx. equivalent to a 16 km walk). Of course, after this test or in use, the shoe regains its original waterproofing once dry.
Shoe waterproofing level.
The 900 Children's Warm boots are waterproof up to 4000 flexes.
Measurement of the boots' thermal insulation.
It was not previously possible to give a precise idea of the temperature at which your shoes would still insulate your feet from the cold. 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. This is how we pinpoint the comfort temperature (100% satisfaction) and the limit temperature (70% satisfaction).
SNOWCONTACT technology.
SNOWCONTACT soles are made using a special component. Designs are optimised to provide excellent all-terrain grip and maximal traction all winter long. What's more, the SNOWCONTACT soles are more effective than conventional soles on snow.
