Shimano RX802 Gravel Cycling Shoes The Shimano RX802 Gravel Cycling Shoes are incredibly light and stiff, designed for gravel racing where pedalling efficiency is key, with no compromise to comfort. The carbon composite sole with a high stiffness rating of 10 ensures all your watts are transferred through the pedals and translated into speed. The upper is constructed from synthetic leather in a one-piece wrap, which supports and stabilises the foot and delivers incredible comfort for all-day riding. An anatomically shaped DYNALAST conforms to the contours of the foot perfectly. Closure is via a single BOA dial and velcro toe strap for a dialled-in feel and easy micro-adjustment. The shoes are kept feeling and smelling fresher for longer thanks to the Silvadur antimicrobial insoles. The outsoles are compatible with two-bolt SPDs, while TPU lugs and anti-slip pads make for easier walking with more traction.
