At just 175 grams (size 42.5), the Empire™ SLX sets a new standard for lightweight cycling footwear. Yet it doesn’t compromise the structure or stiffness needed to put full power to the pedals thanks to a combination of exceptional fit, a new Evofiber™ SL one-piece upper, and the Easton® EC90™ SLX2 high-modulus outsole. And with replaceable heel pads, full titanium hardware and our adjustable SuperNatural Fit Kit, these are full-featured shoes built to win, and built to last. Premium Evofiber™ Upper Evofiber™ takes the best attributes of mesh and microfiber, and fuses them into a single fabric that repels water and improves breathability throughout the shoe. By eliminating the extra seams and adhesives required to insert mesh panels, the durability, comfort and weight of these shoes can all be dramatically improved. Evofiber™ also holds shape exceptionally well, and is fast drying and easy to clean. Supernatural Fit System A superb fit, with adjustable arch support to help optimize comfort and enhance pedaling efficiency. X-Static™ Fiber  X-Static fibers use natural silver to provide heat conductive and anti-microbial properties to help keep your feet warm and your shoes free of odor-causing bacteria and fungus. Easton® Carbon Composite Outsole Unidirectional carbon fiber outsole is engineered to provide a direct connection with the pedal, thanks to class-leading stiffness that puts full effort into forward motion.
