Geox breathes® patented system:

1. The Perforated Sole: the perforated rubber sole contains a special microporous membrane that absorbs and expels sweat without letting water in.

2. The Membrane: this process is made possible as the membrane's micropores are larger than water vapor molecules but smaller than water droplets - keeping water out and feet dry. Sweat, in the form of water vapor can pass through the membrane and out through the perforated sole

3. The Result: the gradual elimination for humidity from the inside of the shoe recreates the ideal microclimate for healthy feet. No more bad odors. Your feet will stay warm and dry in winter, and cool and dry in summer.
