Leather has a porous structure. This gives it the advantage of letting the foot breathe. But this is also its main disadvantage since it tends to absorb water and moisture.
Geox pioneered the technological solution which adds a waterproof feature to the natural “breathing” benefit of leather soles
The Geox Leather patent places a breathable, waterproof membrane into the leather sole, effectively eliminating that uncomfortable, wet feeling we get inside of shoes with leather soles when it rains or when it is wet.
The Geox revolution has been made possible after extensive research resulting in the development of the membrane, made of a special micro-porous material which
expels sweat, in the form of water vapor, but prevents water from penetrating.
The process is made possible as the membrane’s micropores are larger than water vapour molecules, but smaller than water droplets – keeping water out and feet dry.
