The Fox Men's Union BOA Cycling Shoes are engineered to provide ultimate power transfer and a customizable fit for the most demanding trails. Featuring a dual BOA Li2 system, these shoes allow for independent, on-the-fly micro-adjustments across two zones, ensuring a secure and locked-in feel without pressure points. The one-piece welded upper—crafted from a blend of TPU and ripstop—delivers seamless comfort and enhanced breathability while resisting abrasions from trail debris. For protection, a molded toe cap shields against rock strikes, while the Ultratac rubber outsole provides exceptional grip for hike-a-bike sections. Equipped with a D3O insert to dampen vibrations and an internal stiffening plate for pedaling efficiency, the Union BOA is the pinnacle of performance and comfort for trail, all-mountain, and enduro riders.
