Gravel Racing Specific Shoes Shimano’s new RX8 shoes offer you the lightest gravel shoe to their range yet. At the core of the RX800 is a high end carbon sole that employs Shimano's Dynablast technology which improves the ergonomics when pedaling and minimises loss of strength and prevents premature fatigue The shoe is feather weight meaning you have to work less to turn your pedals giving you the most amount of power and performance possible. Super Stiff Carbon Composite Sole The super stiff sole is made of a carbon composite and helps you apply all of your power through your pedals. Specifically engineered for gravel riders the shoes offer the rider an SPD pedal system in a hybrid road/mtb shoe. This provides the desired pedal platform that balances pedal performance with the need for added grip and the ability of the rider to be able to walk on lose surfaces. The upper compound aims to provide a balance of holding power whilst still be comfortable for long days in the saddle.
