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.
The "R": The final "R" in RX8R stands for "rally", and indicates that this model comes with a stitched in (non-removable) ankle for extra protection from the elements and a more glove like fit in the upper.
