Ride rock gardens with confidence in the Fox Union Mountain Bike Shoe
What Our Gearhead® Experts Are Saying:
"I've ridden these through a full season of rocky singletrack, and the BOA dial lets me micro-adjust fit without ever stopping to bend down. The toe cap has taken a few direct rock strikes that would've ended a lesser shoe."
Technical singletrack tends to reveal weak links fast, loose fit, soft toes, pedals that never quite feel connected, and the Fox Union Mountain Bike Shoe is built to close those gaps. A quick turn of the BOA dial locks feet into place mid-ride, so power transfer stays consistent whether grinding up a climb or hammering through a rock garden.
The molded toe cap shrugs off strikes that would otherwise end a ride early, and the Ultratac rubber outsole holds grip across loose dirt, wet roots, and everything between. Exchangeable arch support lets the fit adjust to the rider rather than the other way around, so long days in the saddle stay comfortable from the first pedal stroke to the last.

Frequently Asked Questions
How should I choose a size and pedals for the Fox Racing Fox Union Mountain Bike Shoe?
Choose the men’s size by comparing your foot length with Fox’s shoe-size chart, and consider foot width as well if you need a roomier or narrower fit. This shoe uses a two-bolt cleat interface, so pair it with compatible two-bolt clipless pedals.Where is the Fox Union Mountain Bike Shoe best suited to ride?
It’s suited to trail and enduro riding, with a pedal-focused design for time on the bike and rubber traction for short hike-a-bike sections. It works well in mild-to-warm conditions, but it isn’t an insulated or fully waterproof shoe.How does the Fox Union compare with a hiking shoe for hike-a-bike?
The Fox Union prioritizes secure pedaling and bike control, while a hiking shoe is better suited to extended walking. Its trail traction and toe protection are useful when pushing your bike, but the stiff cycling-focused construction is less comfortable for long hikes.How do I set up the Fox Union for clipless pedals?
Install compatible two-bolt cleats, then position them to support a comfortable, natural foot stance on the pedals. Recheck cleat security after setup and adjust the shoe’s closures for a snug hold without pressure points.How should I clean and dry the Fox Union Mountain Bike Shoe?
Brush off dirt, then clean the upper with lukewarm water, mild soap, and a soft brush. Air-dry the shoes at room temperature away from direct heat, and avoid machine washing, solvents, and treatments intended to make them fully waterproof.
