QUECHUA SH900 Women's Warm and Waterproof Snow Hiking Boots - Navy

During the waterproofing test, we test 3 levels of waterproofing: 2 000 flexes (around 2 hours of walking), 4 000 flexes (around 4 hours of walking) and 8 000 flexes (around 8 hours of walking). After this test or in use, the shoe regains its original waterproofing once the product is dry.

It was not previously possible to give a precise idea of the temperature at which your shoes would still insulate your feet from the cold. Now it can be done: the temperature limits for use are shown on your Quechua shoes. Using cold sensing tests while hiking and in the lab with a panel of customers, we measured the thermal resistance of our boots while active and at rest. We take into consideration the differences between men and women.

These boots, which are laboratory and field tested, provide optimum waterproofing and breathability. First the boots are immersed in water while internal air pressure is applied: the boots are checked to ensure that no bubbles form on the surface of the boots. They are half immersed and placed on a mechanical arm that simulates walking. we then check that the inside of the boots remains perfectly dry.

The boots 900 Warm women remain waterproof for over 4000 flexes.

All our boots are tested in use and for comfort by users who are representative of the target market under conditions that replicate those you will experience in use. Our Missions Tests link up the product manager with people who are not affiliated to Quechua to test, develop and approve the products.

It was not previously possible to measure precisely the temperature at which your footwear would still insulate your feet from the cold. Now it can be done: the temperature limits for use are shown on your Quechua boots. Using subjective sensory chill tests conducted in the field and in the lab with a panel of customers, we measure the thermal resistance of our boots when the user is moving and stationary. We take into consideration the differences between men and women.

Laboratory tests were conducted to test the following elements: attachment of eyelets and straps, fixtures, toxicology, UV resistance, sole and upper component abrasion and premature ageing.
