The Shimano RX801 pulls the best features from Shimano's high-end road and mountain line into a featherweight gravel racing shoe made to go fast. Featuring the stiffest carbon composite sole in Shimano's gravel lineup every pedal stroke is enhanced into high power output that makes us want to push the pace just a little bit harder. BOA dials give us micro-adjustments to dial in our fit with precision while the abrasion-resistant TPU lugs offer extra grip for hike-a-bike situations.
