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. Enhance your footwear collection by adding this pair of sneakers. The classic Geox rubber sole is based on an exclusive patent- the combination of the perforated sole and the resistant breathable and waterproof membrane that allows natural temperature regulation, thereby creating the perfect microclimate inside the shoe that keeps feet dry and comfortable for the whole day.
