What Our Gearhead® Experts Are Saying:"The Fox Racing Union BOA is the trail shoe I recommend when someone wants genuine performance without giving up walkability. The dual BOA Li2 system dials in fit across two zones independently so the shoe stays locked through technical riding without creating pressure points on longer efforts. The Ultratac outsole with the D3O insert grips flat pedals exceptionally well, and the molded toe cap gives real confidence on chunky terrain. Stiff enough for efficient pedaling, comfortable enough to hike when the trail demands it."Trail riding rewards shoes that can keep up with the terrain, and Fox Racing's Union BOA is built to do exactly that. The dual BOA Li2 closure gives you two independent adjustment zones so fit stays precise and responsive through the full range of a hard ride, whether that's a long grind to the top or a technical descent that demands everything from your feet and ankles.The welded TPU and ripstop upper handles abrasion from brush, rock, and repeated impacts without adding unnecessary weight, and the molded toe cap takes the edge off unexpected strikes on technical lines. The Ultratac rubber outsole with integrated D3O insert delivers grip on flat pedals that holds through wet roots and loose rock alike, while the stiff internal plate transfers power efficiently without turning the shoe into something miserable to walk in at the trailhead. Two-bolt cleat compatibility covers the full range of clipless setups for riders who prefer that system. The Union BOA is the shoe that works as hard as the riding does.
