We perform comparative studies carried out in a thermal laboratory, in walking conditions in light winds (5km/h). This is how we measure the thermal resistance of our boots. However every individual feels the cold differently.Comfort temperature: felt slightly cold & 70% of users find the thermal sensation acceptable on their feet.Limit temperature: felt very cold & 10% of users consider the thermal sensation acceptable on their feet.

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 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). Your boots were tested to 4000 flexes, which is equivalent to 8 km of walking.

The boots’ traction depends on the number and shape of the studs (4mm 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 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.

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.

Boots can become heavy while they’re being worn in the wet (condensation and perspiration)If your boots are very wet, we advise you to remove the insole, fill the upper with balls of newspaper and change them regularly. The paper will soak up the moisture and speed up the drying process.Never place your boots too close to a heat source but leave them in a warm, dry and ventilated place.

Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products. Today, this product is not eco-designed, but we work every day to make it more responsible: eco-design, reparability and durability at the heart of our development process.

Our Decathlon Sportslab laboratory, based in Lille, also contributes to the innovation and development of our Quechua products. It brings together 4 themes, each with their own area and technological tools:Morphology (including 3D analysis)Motion scienceThermal comfort (with its four climate chambers)Behavioural and sensory scienceWe test seam strength, bonding, toxicology, UV and abrasion resistance, among other things.

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