We chose a warm lining that has insulation to give you effective protection from the cold. We assess the thermal insulation of our shoes based on the field and laboratory tests carried out to measure the perceived cold by a panel of users. As a result, you now have an accurate measure of the temperature at which you are protected with these shoes. The comfort temperature rating for these shoes is: -10°C for this model.

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.

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 waterproofness test, we test 3 levels of waterproofness: 2,000 flexes (approx. 4 km walk), 4,000 flexes (approx. 8 km walk) and 8,000 flexes (approx. 16 km walk). Your boots were tested to 4,000 flexes, which is equivalent to 8 km of walking.

The boots’ traction depends on the number and shape of the studs (3 mm on this boot). 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.

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 principles : 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. Shoe height: adjust the height of the sock to the height of the boot and preferably choose high models if want more protection.

A fabric's water repellent property is its capacity to make water run off its surface without seeping in. This prevents the fabric from soaking up water and keeps it lightweight, warm and breathable. The water repellent property is achieved by treating the fabric's exterior. This treatment needs to be renewed during the lifetime of the garment. Products (spray or liquid) for this purpose are available in our stores.

This product is guaranteed for 2 years from the date shown on the sales receipt. A product covered by the warranty will be repaired or exchanged free of charge. The warranty covers product defects, excluding those resulting from normal wear and tear and improper use.

The environmental impact of the product is calculated based on its entire life cycle and using different indicators. An ABCDE score is provided to help you easily identify the most environmentally friendly products by comparing the same type of product. Decathlon actively promotes this initiative.
