High-performance fit and pedal control define the Fox Union BOA, built for trail and enduro riders
What Our Gearhead® Experts Are Saying:
"These shoes check all the boxes for aggressive trail and enduro riding. The dual BOA® closure system ensures a perfect fit, and the stiff midsole helps transfer every watt of power into the pedals. The Ultratac™ outsole with D3O® keeps me locked in and stable, while the molded toe cap gives me confidence in rocky terrain. A must-have for riders who push the limits."
Built for riders who demand the best in fit, power transfer, and grip, the Fox Racing Union BOA redefines mountain bike footwear. The dual BOA® Li2 system provides instant micro-adjustments, ensuring a dialed-in fit that won’t slip mid-ride. A molded internal stiffening plate delivers maximum efficiency on the pedals while maintaining enough flex for comfortable off-bike wear.
Protection is built in, with a welded TPU/ripstop upper that stands up to trail abuse and a molded toe cap that defends against rock strikes. The new Ultratac™ rubber outsole, enhanced with a D3O® insert, provides industry-leading grip, keeping us planted on the pedals when charging technical sections. Compatible with 2-bolt cleat systems, these shoes are designed for riders who need uncompromising performance on the toughest terrain.
