EU 40 Arpenaz 100 High Warm Men's Hiking Waterproof Boots - Grey Maroon, Black
High, waterproof and warm footwear. Rubber sole for an increased lifespan and better grip.
Comfort temperature rating when stationary: -11آ° C.in dynamics: -20آ°C.
Breathable, waterproof membrane to keep your feet dry.
SNOWCONTACT technology: optimal grip on snow, 3 mm crampons.
Upper stem with a hook offering a good fit and good support.
Measuring the boots' thermal insulation.
Based on tests on perceived cold conducted in the field and in the lab involving a panel of users, we measure the thermal insulation of our boots when stationary (static) and when moving (dynamic). It is now possible to give a precise temperature rating down to which your boots will protect you. Comfort temperature ratings are indicated on your boots. We take into account the differences in the perception of cold between men and women.
Footwear waterproofing test.
Tested in the laboratory, the shoes give you an optimal impermeability. First immersed in water under air pressure, we check the absence of bubbles on the surface of the shoe. 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).s4
Level of impermeability of the shoe.
This model of boot has been tested up to 2000 flexes, equivalent to 4 km of walking.s5
The SNOWCONTACT soles are designed using a ific component and a lug pattern that is designed to provide the best possible grip and traction. SNOWCONTACT soles are more effective than traditional soles on snow. When used on ice, optimum safety can only be ensured by adding non-slip grips.s6
All our shoes undergo comfort and use tests carried out by users who are representative of our target market, in conditions identical to those found in typical use. Our Field Test Missions involve the product manager and people who are not affiliated with QUECHUA to test, improve and validate our products.s7
