These shoes owe their extraordinary breathability to the GEOX Net Breathing System: the technology developed and designed in collaboration with professional pilots who have won the world championship. The maxiholes guarantee outstanding breathability. The maximum water resistance of the sole is guaranteed by a membrane that prevents water from getting in. What™s more, an additional layer made up of a special protective material guards the foot, without compromising on breathability.This technology has been designed to withstand even the most intense level of activity and to provide maximum day long comfort, even in the more extreme of temperatures.
