FAQs
Are these shoes suitable for gravel riding?
The RC5 shoes are primarily designed for road cycling due to their stiffness and 3-bolt cleat compatibility. While they can be used on light gravel paths, they are not optimized for the mud, debris, and specific cleat systems often preferred for serious gravel biking.
What type of cleats do these shoes use?
The Shimano RC5 shoes are designed for 3-bolt road cleat systems, such as SPD-SL, Look Keo, or Speedplay (with appropriate adapters).
How do I clean the synthetic leather upper?
Wipe the upper with a damp cloth and mild soap if necessary. Avoid harsh chemicals. Always allow the shoes to air dry naturally.
Can the BOA Fit System be replaced?
Yes, replacement BOA Fit Systems are available. If your system is damaged or worn out, you can typically purchase a replacement kit and follow instructions to swap it out.
What is the stiffness rating of these shoes?
The Shimano RC5 shoes have a stiffness rating of 8 out of 12, indicating a good balance between efficient power transfer and rider comfort for performance cycling.
Do these shoes come with cleats?
No, the Shimano RC5 cycling shoes do not include cleats. Cleats are sold separately and must be compatible with a 3-bolt road cleat mounting system.
How much do these shoes weigh?
The shoes are designed to be lightweight, contributing to overall cycling efficiency. Specific weight varies slightly by size, but they are built for performance where weight is a factor.
Troubleshooting
BOA dial is difficult to turn or stuck.
Check for debris around the dial and cable. Gently clean with a soft brush or damp cloth. If damage is suspected, contact customer support.
Uneven pressure or hot spots when wearing the shoes.
Ensure you have correctly installed your cleats and that the shoe is the right size. Re-adjust the BOA dial, ensuring even tension across the foot. Check for any internal seams or debris causing discomfort.
Shoes feel slippery on the pedals.
Verify that your cleats are properly aligned and securely fastened to the shoe. Ensure the pedal surfaces are clean and free of mud or debris.
Upper material feels stiff or causes irritation.
Allow a break-in period for the shoes. Wear them for shorter rides initially and gradually increase duration. Ensure socks are appropriate and not bunching up.

Setup, Compatibility & Care
Setup:
Ensure the shoes are the correct size. Consult sizing charts if unsure.
Install your preferred cycling cleats (not included) onto the sole’s cleat mounts. Ensure they are tightened securely.
Put on the shoes and use the BOA Fit System dial to tighten the laces evenly. Turn the dial clockwise to tighten and pull it outwards to release.
Compatibility:
These shoes are compatible with 3-bolt road cleat systems (e.g., SPD-SL, Look Keo, Speedplay).
The stiffness rating of 8 makes them suitable for most road cycling disciplines, including racing, training, and endurance riding.
Care:
Cleaning: Wipe the synthetic leather upper with a damp cloth. Avoid harsh chemicals or abrasive cleaners. For stubborn dirt, use mild soap and water, then wipe clean.
Drying: Allow shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or hairdryers, as this can damage the materials.
BOA System: Periodically check the BOA cable and dial for debris. The dial can usually be wiped clean. If the cable becomes frayed, contact Shimano for replacement parts or service.
