Am I sure my shoes are warm enough for winter hiking?
We carry out comparative studies in a thermal laboratory, under walking conditions with light winds (5km/h). This enables us to measure the thermal resistance of our shoes. However, each individual has his or her own sensitivity to cold.
Comfort temperature: slightly cold sensation & 70% of users find the thermal sensation on their feet acceptable.
Limit temperature: very cold sensation & 10% of users find the thermal sensation on their feet acceptable.
How do my shoes protect me from the elements?
Your shoes have been designed with a membrane to ensure waterproofing and breathability. A membrane is a very thin component (5 to 25 micrometers) affixed to the inside of a fabric that keeps water out while allowing moisture to escape.
Breathable footwear for optimum thermal comfort
Thermal comfort is a balance between the warmth provided by the footwear and its ability to let the foot breathe. Too much warmth or not enough breathability, moisture accumulates and the cold can set in. We've designed your shoes with your occasional or regular practice in mind, with a membrane whose role is to keep water out on one side and allow moisture to escape on the other.
How can I be sure that my shoes are 100% waterproof?
We've ensured that your shoes 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 shoe model has been tested up to 4,000 flexes, equivalent to 8 km of walking.
Will my shoes 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, bonding, 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 shoes?
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.
