The NRG S500 features an ice blue monochrome colorway for one of our most technologically advanced shoes. The Eco-Lite™ sole is an ultra lightweight material that's ergonomically designed for maximum comfort. The pattern of the sole flows seamlessly into the breathable lines on the upper part of the shoe and out through the shape of the tongue and cuff. With no surprise, the NRG has earned the reputation as the world's most comfortable shoe while maintaining the elegance of luxury fashion.
