Nebula S is the super-lightweight and flexible sneaker made to breathe and designed to hit the city. The perfect match of any business or smart business outfits during the day, and of any casual wear in the evening, it's also the ideal sneaker for commuting or moving fast around town. Nebula S breathes in all directions, thanks to its 3D Breathing System, the combination of the Geox patented Net Breathing System full membrane and the 3D mesh footbed, for a breathability and comfort never experienced before. The Nebula S inner Elastic sock - an airmesh lining mapped by hi-frequency applications - is fixed to the upper only on few specific points and, beside providing excellent cushioning, enhances breathability thanks to its "Air-escape" design that canalizes air all around the foot and makes heat expulsion easier. The sole is super-lightweight and responsive, thus making every step extremely effective on hard city grounds. Grooves on the ergonomic outsole provide excellent flexibility. The iconic Geox Nebula outsole with its 3D Performance Units has been adapted with Rubber tripods featuring a concentric circles design for an even more efficient grip on smooth surfaces, providing Nebula S with the maximum balance and support. To top it all, Nebula S double and dynamic fit offers the maximum foot comfort, all day long.
