QUECHUA SH100 X-Warm Children's Snow Boots - Pink

Based on the field and lab tests carried out to measure the perception of cold with a panel of users, we gauge the thermal insulation of our boots when stationary (static) and when moving (dynamic). It is now possible to give an accurate measurement of the temperature at which the boots will protect you. The comfort temperature ratings are indicated for the boots. We take into account the differences in the perception of cold between men and women.

These boots, which have been tested in the laboratory, provide the best possible waterproofing. The boots are initially immersed in water with pressurised air inside to check for bubbles on the surface of the boot. Then they are placed on a mechanical arm to simulate a walking motion while half immersed in water. We then check if the inside of the boot remains perfectly dry. These laboratory tests are supplemented with wear and ageing tests conducted in the field.

During the waterproofing tests, we test 3 levels of waterproofing, with 2000 flexes (approx. equivalent to a 4 km walk), 4000 flexes (approx. equivalent to an 8 km walk) and 8000 flexes (approx. equivalent to a 16 km walk).
