Thanks to the HDry® quality standard, the shoes built with this system possess the highest level of waterproofness, breathability and insulation. The waterproof and breathable membrane is firmly laminated to the upper inner side and there are no seams and no gaps where water can penetrate: rain and cold are blocked on the shoe’s outer surface and a large volume of dry air keeps your feet warm and comfortable. The ultra-thin waterproof membrane and the unique lamination method provides a precise fit and keep your shoes dry and light all day.
