Geox Amphibiox® is now a system that offers comfort and waterproof solutions specifically developed to meet the needs of a varied range of situations and environmental conditions, from the degree of water immersion required, to the desired grade of heat insulation. A special breathable, waterproof membrane protects both the sole and the upper, preventing water from entering the shoe, while maintaining Geox’s extraordinary breathability. This helps maintain an ideal comfortable microclimate for your feet, which stay warm, dry and can breathe naturally.
