Measurement of the thermal insulation of our boots:
Based on field and lab tests carried out to measure the perceived cold by a panel of users, we gauge the thermal insulation of our boots when stationary (static) and when moving (dynamic). It is therefore possible to accurately know down to what temperature your boots will protect you. The comfort limit temperature ratings are indicated for the boots. We take into account the differences in the perception of cold between men and women in our data.
Footwear waterproofing test:
These boots are tested in the laboratory to guarantee optimum waterproofing. The boots are initially immersed in water with pressurised air inside to check for bubbles on the surface of the boot. Then they are placed on a mechanical arm simulating walking, half immersed in water. We check that the inside of the boot stays perfectly dry. These laboratory tests are supplemented by user and ageing tests conducted in the field.
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).
Waterproof rating of the boot:
This model of boot has been tested for up to 4000 flexes, which is equivalent to 8km of walking.
This boot has been tested in the field under the same climatic conditions in which it will be used by hikers accompanied by the product manager. In particular, we analyse the technical elements of the boot to validate the product in accordance with its specifications and the reviews that you send us.
Our engineers conduct laboratory tests to guarantee your full satisfaction in use. We validate the following elements among other things: strength of the eyelets and straps, strength of the glued assemblies, toxicology, UV resistance, abrasion resistance of the sole and upper components and accelerated ageing.
