Product Information

Full details

The Fox Union BOA Clipless Shoes are designed for mountain bikers seeking a high-performance, durable, and highly adjustable footwear solution for trail riding. These shoes excel by providing exceptional power transfer and off-bike grip; however, they require compatibility with standard 2-bolt cleat systems and may be stiffer than traditional flat-pedal footwear. Featuring the precise dual BOA Li2 system and a rugged Ultratac rubber compound, these shoes offer a secure, customized fit and reliable traction on varied terrain.

Setup, Compatibility & Care

To set up your shoes, attach your preferred 2-bolt mountain bike cleats to the sole mounting plates. Ensure all bolts are tightened securely to the manufacturer's torque specifications. If you feel pressure on your arches, swap the pre-installed arch support with the alternative option included in the box.

For care, remove excess mud and debris after each ride using a soft-bristled brush. Wipe down the upper with a damp cloth. Do not submerge the shoes in water or use harsh chemical cleaners, as this can degrade the specialized materials. Always air-dry the shoes in a cool, shaded area; avoid direct heat sources like radiators, which can warp the stiffening plate or damage the BOA lacing components.
