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 -11°C) and when moving (dynamic -20°C). As a result, you now have an accurate measure of the temperature at which you are protected with these shoes. The comfort temperature ratings for your shoes is shown. We take into consideration the differences in feeling between men and women.

Your boots are designed with a membrane to guarantee waterproofing and breathability. A membrane is a very fine component (5 to 25 micrometres) affixed to the inside of a fabric that prevents water from entering while allowing moisture to escape.

Thermal comfort is a balance between the warmth of the boots and its ability to let the foot breathe. Too much heat or not enough breathability means that damp accumulates and cold can set in. We have designed your boots with your activity in mind, be it occasional or regular, with a membrane which prevents water ingress and lets damp out.

We made sure that your boots are waterproof by conducting laboratory tests to simulate walking with the boots half submerged in water. We also conducted field tests to measure wear and ageing. During the waterproofing test, we test 3 levels of waterproofing: 2,000 flexes (approx. 4 km walk), 4,000 flexes (approx. 8 km walk) and 8,000 flexes (approx. 16 km walk). This model of boot has been tested for up to 2,000 flexes, which is equivalent to 4 km of walking.

The traction of the boots depends on the number and shape of the studs. The grip is dependent on the materials of the sole and the tread pattern, like the tyres of your car. Traction optimises propulsion, prevents the boot from slipping backwards when going uphill and stabilises the boot. Grip prevents the boot from slipping and skidding on smooth ground or in demanding conditions (rain, snow, ice) by giving the sole grip.

Equipped with SNOWCONTACT soles, your boots are designed for maximum grip comfort for hiking and traction on snow. The arrangement and the height of the studs (3 mm) are strategically placed for optimal grip when hiking on snow. The surface and layout of the studs are designed to perfectly grip the layer of hard snow and evacuate excess water to avoid slipping.

SNOWCONTACT soles are made with a specific component and stud pattern that is designed to ensure the best possible grip and traction. SNOWCONTACT soles are more effective than traditional soles on snow. When walking on ice, the only way to ensure optimum safety is to add anti-slip grips to your boots.

Our engineers conduct laboratory tests to ensure that the product fully complies with your satisfaction in use. Our verifications include the following elements: tearing eyelets and straps, gluing, toxicology, UV resistance, abrasion resistance of outsole and upper components, accelerated ageing.

To be well equipped in winter, we recommend that you follow these guidelines : Warmth: warmth provided by a warm pair of socks (ideally containing a suitable percentage of wool)Breathability: Choose the sock according to the intensity of the hike and make sure you wear a breathable model to minimise moisture.Boot height: adapt the height of the sock to the height of the upper and preferably choose high models if you want more protection.

Store your products in a well-ventilated room away from light and moisture.
