Made for Our design team has developed this boot for your occasional hiking on any type of snow. Keep your feet warm and dry. These warm and waterproof boots will bring you good protection and thermal insulation over its full height. They are easy to put on thanks to their simple and effective lacing system.
Measurement of the thermal insulation of our boots:
Based on the field and lab tests carried out to measure the perception of cold with a panel of users, we gauge the thermal insulation of our boots when stationary (static) and when moving (dynamic). It is now possible to know precisely up to what temperature your shoes protect you. The comfort temperature ratings are indicated for the boots. We take into account the differences in the perception of cold between men and women.
Boot impermeability test:
These boots, which have been tested in the laboratory, provide the best possible 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 then check if the inside of the boot remains perfectly dry. These laboratory tests are supplemented with wear 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).
Level of impermeability of the boot:
This model of boot has been tested up to 4000 flexes, equivalent to 8 km of walking.
This boot has been tested in the field in climatic conditions adapted to its use by hikers accompanied by the product manager. In particular, we analyse the technical elements of the boot to validate the product in relation to its specifications and the feedback that you send us.
Our engineers conduct laboratory tests to fully guarantee your satisfaction in use. Among other things, we validate the following elements: strength of eyelets and straps, strength of glued assemblies, toxicology, UV resistance, abrasion resistance of the sole and upper components and accelerated ageing.
We advise you to store your products in a ventilated room protected from light and moisture.
