This fine material has important features such as long-term waterproofing capacity, excellent resistance to the most extreme temperatures & high resistance to wear & tear. The special microporous structure of the GORE-TEX® fabric in expanded PTFE contains around 1.4 thousand million microscopic pores per square centimetre. These pores are Approx. 20, 000 times smaller than a drop of water, but 700 times larger than a molecule of water vapour. So while water cannot penetrate the GORE-TEX® membrane in liquid form, sweat (water vapour) can easily evaporate. This results is a completely waterproof barrier that means the boot can be used in all climates, guaranteeing maximum comfort & optimal breathability.
