The Union BOA Flat uses the same one-piece, welded upper construction as the Union BOA, including a molded toe cap and reinforced toe box to protect against the elements and rock strikes. The BOA Dual Dial Li2 system offers a secure and precise fit with on-the-fly micro-adjustability and multidirectional adjustments for tightening and loosening. Combined with Fox’s proprietary Ultratac™ outsole with best-in-class grip and durability, the Union BOA Flat provides improved power transfer to the pedals and added confidence on and off the bike. The custom hex-shaped lugs are specifically designed to deliver control on flat pedals, while the toe and heel lug spacing is suited for hike-a-bike sections.
