In our Sportslab, products are tested for warmth, ergonomics, and strength. Then it's out to the mountains for the ultimate field test.
Thermal testing
In the lab (in simulated conditions) and out in the mountains, the boots are tested by a variety of users. We ask them to report when their feet begin to feel cold, and found that these boots keep most people comfortable down to -23°C (standing still) or -32°C (walking).
Strength tests
In the lab, our engineers test for strength by accelerating the ageing process and exposing the boots to UV rays. They check that all components - like eyelets, straps, and glues - will resist abrasion in all kinds of conditions.
Store your products in a dark, dry and well-ventilated place. Remove the liner regularly to dry it. Machine wash the liner at 30°C max but do not tumble dry.
