FAQs

Are these shoes waterproof?

The Fox Union Mountain Bike Shoes are water-resistant due to their construction but are not fully waterproof. They are designed to handle splashes and wet conditions but may not be suitable for prolonged submersion or very heavy rain without additional protection.

What type of pedals are compatible with these shoes?

These are clipless mountain bike shoes and are compatible with most standard 2-bolt clipless pedal systems, such as SPD.

How do I adjust the fit on the fly?

The Dual BOA Li2 system allows for micro-adjustments. Turn the dials clockwise to tighten and pull the dials outwards to release tension. You can make small adjustments throughout your ride as needed.

Can I replace the Ultratac rubber sole if it wears out?

The Ultratac rubber sole is integrated into the shoe's construction and is not designed to be user-replaceable. However, the compound is known for its durability and long-lasting performance.

What is the difference between Polyester and Nylon uppers?

While both offer durability, Nylon generally provides superior abrasion resistance and can sometimes offer better flexibility. Polyester might be chosen for its specific weight or cost characteristics. Both are combined with ripstop for added toughness.

How do I clean mud off the shoes?

Use a soft brush to remove loose dirt and mud. Then, wipe the shoes with a damp cloth and mild soap. Rinse the cloth and wipe again to remove soap residue. Allow to air dry.

Troubleshooting

BOA dial is stiff or difficult to turn

Check for any debris caught in the dial mechanism or lace path. Gently clean with a dry brush. If the issue persists, the lace may need to be re-routed or the system inspected further.

Foot feels uncomfortable or has pressure points

Readjust the BOA dials for a more even tension. Experiment with the included arch support options to find the best fit for your foot.

Cleats do not engage with pedals properly

Ensure cleats are correctly installed and aligned on the shoe sole. Verify compatibility between the shoe's cleat mounting system and your pedals. Check pedal tension.

Poor grip when walking

Ensure the Ultratac rubber sole is clean. For significantly worn soles, consider replacement if available, or use caution on slippery surfaces.

Setup, Compatibility & Care Instructions

Compatibility:

  • Available in various sizes and some models may feature different materials (Polyester, Nylon) impacting breathability and weight.

Care:

  • Clean the shoes with a damp cloth and mild soap after riding. Avoid abrasive cleaners.
  • 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 and adhesives.
  • Inspect the BOA system regularly for debris and ensure the laces move freely. Clean with a dry brush if necessary.
  • Store in a cool, dry place when not in use.
