FAQs
Are these shoes suitable for everyday walking?
While the Kestrel Boa features a grippy outsole for dismounted walking, their primary design is for cycling. The stiffness that benefits pedaling may make them less comfortable for extended periods of walking compared to dedicated walking shoes.
What is the main advantage of the BOA Fit System?
The BOA Fit System allows for precise, even tensioning across the foot with a simple dial. It enables quick adjustments on the fly without needing to stop and manually re-tie laces, providing a secure and comfortable fit.
How do I clean the synthetic upper?
Wipe the synthetic upper with a damp cloth. For tougher dirt, use a small amount of mild soap and water. Always allow the shoes to air dry naturally.
What type of pedals are compatible with these shoes?
These shoes are designed for clipless mountain bike pedal systems that use a 2-bolt cleat mounting pattern, such as the Shimano SPD system.
Do these shoes have good traction when walking?
Yes, they feature a minimal XC-style tread pattern and a patch of rubber behind the cleat recess designed to provide ample traction when riding unclipped or walking the bike.
Can I replace the BOA laces if they get damaged?
Yes, BOA replacement lace kits are typically available. You can check the BOA website or contact Five Ten customer support for information on replacement parts.
What makes these shoes stiffer than other Five Ten models?
The Kestrel Boa is engineered with a focus on maximum power transfer, featuring a stiffer internal shank and sole construction compared to models designed for more casual trail riding or freeride applications.
Troubleshooting
BOA dial is difficult to turn or stuck
Ensure the laces are not tangled. Gently clean the dial and lace area with a dry brush. If the issue persists, contact customer support.
Shoes feel too tight/loose
Adjust the BOA dial for micro-adjustments. Ensure the hook-and-loop strap is secured properly. Try different lacing tensions to find your ideal fit.
Cleats don't engage with pedals properly
Check cleat alignment and ensure they are installed correctly. Verify compatibility with your pedal system. Adjust cleat position slightly if needed.
Slipping heel
Tighten the BOA system and the hook-and-loop strap. Ensure your socks are not bunching up. The non-slip heel cup should help minimize this; if it persists, consider insoles or a different sock combination.

Setup, Compatibility & Care
Setup:
Cleat Installation: The shoes are designed for clipless pedal systems. Install your preferred cleats onto the cleat recess on the sole according to the cleat manufacturer's instructions. Ensure the cleats are oriented correctly for your pedal system (e.g., Shimano SPD).
Fit Adjustment: Use the BOA dial to tighten the laces evenly. Turn the dial clockwise to tighten and pull it outwards to release. Adjust the hook-and-loop strap for additional security as needed.
Compatibility:
Pedals: Compatible with most standard 2-bolt clipless pedal systems (e.g., SPD).
Socks: Recommended to wear cycling-specific socks for optimal comfort and performance.
Care:
Cleaning: Wipe down the synthetic upper with a damp cloth. For stubborn dirt, use mild soap and water. Avoid harsh chemicals or abrasive cleaners.
Drying: Allow shoes to air dry completely at room temperature. Do not place them near direct heat sources like radiators or in direct sunlight, as this can damage the materials.
BOA System: Keep the dial clean. If debris obstructs the mechanism, gently clean with a dry brush. Avoid excessive force on the dial.
