Full details
The Fox Union Cycling Shoes are high-performance clipless shoes designed for mountain bikers who demand precision, comfort, and durability on technical trails. Featuring a dual BOA Li2 system for effortless micro-adjustments and an Ultratac rubber outsole for maximum grip, they excel in power transfer and impact protection. While these shoes offer a premium fit and advanced technical features, riders should note that they require clipless-compatible pedals and cleats to function as intended.

FAQs
Are these shoes compatible with road bike pedals?
No, the Fox Union shoes are designed for 2-bolt mountain bike style cleats and are not compatible with 3-bolt road pedal systems.
Can I replace the arch support inserts?
Yes, the shoes come with interchangeable arch support options to help you customize the fit to your specific foot shape.
How do I tighten the fit while riding?
Use the dual BOA Li2 dials located on the side of the shoe. Simply turn them clockwise to tighten and pull up to release the tension.
Are these shoes waterproof?
While the welded TPU and ripstop upper is durable and water-resistant, they are not fully waterproof and are intended to be breathable.
What is D3O cushioning?
D3O is an impact-protection material integrated into the shoe that stays flexible during normal movement but hardens instantly upon impact to protect your feet.
Troubleshooting
Difficulty clipping in or out of pedals
Adjust the spring tension on your pedal system and ensure the cleat bolts are fully tightened and flush with the shoe sole.
BOA dial feels stiff or stuck
Check for debris or dried mud under the dial; gently clean the area with a soft brush and clean water, then test the mechanism again.

Setup, Compatibility & Care
To set up your Fox Union shoes, attach your preferred 2-bolt mountain bike cleats to the sole mounting plates. Ensure the bolts are tightened to the manufacturer's torque specifications. These shoes are compatible with standard mountain bike clipless pedal systems. For care, it is recommended to clean the shoes after muddy rides by wiping the exterior with a damp cloth and mild soap; avoid submerging them in water. Allow the shoes to air dry naturally in a well-ventilated area, avoiding direct heat sources like heaters or radiators, which can damage the materials and adhesives.
