We have selected warm and insulating materials for this boot, providing good protection against snow and cold. We have tested it in the laboratory and in the field with our user representatives. We checked the temperature up to which it stays comfortable when you're stationary and when you're walking, as this varies a lot: 25°F when static and 3°F when moving. And we took into account how temperature is felt differently by men and women.

Your boots have been designed with a membrane to ensure optimal water-resistance. A membrane is a very thin component (5 to 25 micrometers) affixed to the inside of a fabric that prevents water from entering while allowing moisture to escape. While you stay warm in your boots, your feet will also stay dry. The sole insulates from the cold coming from contact with snow.

Thermal comfort is a balance between the warmth of the boots and its ability to allow the foot to 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, regular and sometimes intense, with a membrane whose role is to prevent water from entering on 1 side while allowing moisture to escape on the other.

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 aging. During the waterproofing test, we test 3 levels of waterproofing: 2,000 flexes (about 2.5-mile walk), 4,000 flexes (about 5-mile walk), and 8,000 flexes (about 10-mile walk). This model of boot has been tested with up to 8,000 flexes, which is equivalent to 10 miles of walking.

The grip of the boots is linked to the studs, their number and shape. Traction depends on the materials and ridges used on the soles, like your car's tires. Traction optimizes propulsion, prevents the boot from slipping backward when going uphill, and stabilizes the boot. Grip prevents the boot from slipping and skidding on smooth ground or in demanding conditions (rain, snow, ice) by giving grip to the sole.”

The SNOWCONTACT soles are designed using a specific component and stud pattern (5 mm) to provide 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.

The support provided by your boot is essential for your comfort when walking. Indeed, good support optimizes your steps on hilly terrain (ascent and descent), prevents your foot from sliding in the boot, and reduces the occurrence of blisters. There is less loss in the transmission of your energy to the boot and therefore less fatigue. This is especially important when you are snowshoeing.

We designed these boots for hiking on snow, with or without snowshoes. The upper of the boot (mid-height type) combined with gaiters (external or integrated in the pants), provides good protection against snow getting in. Waterproof and warm, their support and rigidity are more suitable for walking with snowshoes.

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 aging.

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