The Sidi X-Power CE motorcycle boots are lightweight and robust. They have a water-repellent TechnoMicrofibre construction and a soft inner lining for superior comfort and maximum wearability. A thermoformed microfibre tongue and rear joint give comfort and durability, and Sidi's Flex system limits flexion through a mechanism inside the joint to increase safety. The smooth inner surface provides optimum grip with the bike, maximising the feel and preventing paintwork damage. Four replaceable micrometric levers with adjustment memory provide the perfect custom fit. The calf protector has a non-slip rubber insert and is heat resistant. The inside of the boot has a smooth design specially designed for better contact and grip with the motorcycle.
