Fizik Vento Proxy Fast and Breathable Clipping into your pedals provides more pedaling power and efficiency. With a stiff mountain bike shoe, you'll be able to conquer your next ride and beat your previous records. The Fizik Vento Proxy is an off-road racing cycling shoe developed for competitive riders seeking race-ready features and efficient power transfer on unpaved roads. The Proxy is well ventilated thanks to an innovative translucent PU-laminated mesh that makes the shoe both lightweight and comfortable. The upper is durable, thanks to its tearproof construction, protecting you from the pitfalls of rowdy riding on rough terrain. The closure pattern is minimal and supportive, using BOA textile lace guides that balance tension and further eliminate pressure hot spots. The newly redesigned X3 carbon-reinforced nylon outsole offers more stiffness for efficient power transfer. The generous rubber tread delivers better grip on the pedals and improved traction for dismounted segments during CX races.
