Am I sure my boots are warm enough for winter hiking?
We carry out comparative studies in a thermal laboratory, under walking conditions in light winds (5km/h). This enables us to measure the thermal resistance of our boots. However, each individual has his or her own sensitivity to cold.
Comfort temperature: slightly cold sensation, and 70% of users consider the thermal sensation on their feet to be acceptable.
Limit temperature: very cold sensation, and 10% of users consider the thermal sensation on their feet to be acceptable.
How do my boots protect me from the elements?
Your boots have been designed with a membrane to ensure waterproofing and breathability. A membrane is a very thin component (from 5 to 25 micrometers) affixed to the inside of a fabric that keeps water out while allowing moisture to escape.
How can I be sure that my boots are 100% waterproof?
We've ensured that your boots are waterproof with laboratory tests simulating walking with feet half-submerged in water, and with use and ageing tests in the field. In the waterproof test, we test 3 levels of waterproofness: 2000 flexions (approx. 4 km walking), 4000 flexions (approx. 8 km walking) and 8000 flexions (approx. 16 km walking).
Your boots have been tested at 4000 flexions equivalent to 8 km walking.
What's the difference between grip and adhesion?
Boot grip depends on the number and shape of studs (4mm on this boot). Grip, on the other hand, depends on the materials and treads used on your soles, much like the tires on your car. Grip optimizes propulsion, prevents the boot from skidding backwards when climbing and stabilizes the boot.
Grip prevents the boot from slipping and skidding on smooth terrain or in demanding conditions (rain, snow, ice), by providing grip to the sole.
Will my boots stand up to regular use over time?
Our engineers conduct laboratory tests to guarantee your complete satisfaction in use. We validate the following elements, among others: eyelet and strap resistance, gluing, toxicology, UV resistance, abrasion of sole and upper components, accelerated aging.
How do I get the right footwear for hiking on snow?
To get the best outfitting for winter, we recommend the following principles:
Warmth: warm socks (ideally with a suitable % wool)
Breathability: choose socks according to the intensity of the hike, and in particular choose breathable models to limit humidity.
Stem height: adapt the height of the sock to the height of the stem, and prefer high models if you're looking for more protection.
How can I preserve the technical qualities of my boots?
A fabric's water repellency is its ability to let water slide off its surface without absorbing it. This means the fabric doesn't become waterlogged, and remains light, breathable and warm. Water repellency is achieved by a treatment applied to the outer face of the fabric. This treatment needs to be renewed over the life of the garment. Products (spray or liquid) are available for this purpose in our stores.
