A purebred gravel racing shoe designed to be as fast and light as a road shoe, while maintaining the comfort and durability of a mountain bike shoe. The RX8 series from Shimano gets a fresh redesign and BOA's new Li2 dial, which allows for a micro-adjust both to tighten and loosen the shoe. A full carbon composite sole keeps the shoe stiff for when you put power through the pedals. A shoe made for xc, cross, gravel races, and those long gravel events, the RX8R does it all.
