Thanks to a special membrane that is permeable to vapour but impermeable to water, rubber outsoles are able to breathe and leather outsoles remain waterproof. Immaculately designed, this pair of sneakers will help you upgrade your footwear collection. Geox evergreen soles are based on an exclusive Geox patent, the combination of a perforated sole and a breathable and waterproof membrane allowing natural Thermoregulation which creates an ideal microclimate inside the shoe in order to maintain dry feet throughout.
