Fox Union Boa Flat: High-performance shoes to enhance your ride experience

The Fox Union BOA® Flat shoes are designed to boost your confidence to new levels on your MTB adventures. Tailored for the trails, these shoes provide a personalized fit thanks to the integrated Dual BOA® Li2 system. Our flagship model pushes boundaries once again with a completely redesigned upper (combining welded TPU and ripstop for durability and improved breathability), as well as enhanced construction and fit. This flat-pedal version of the Fox Union BOA® offers perfect grip on platform pedals and features rugged elements, including a molded toe cap to protect against rock impacts. Lightweight and well-fitted, their low-profile EVA midsole—specifically developed for this model—improves pedal feel and grip for greater comfort. The molded internal reinforcement plate maximizes power transfer without compromising off-the-bike comfort. The outsole is made from our Ultratac™ rubber compound, with lug patterns that deliver class-leading grip and durability. Versatile and sleek, the Fox Union BOA® Flat MTB shoes are made to follow you everywhere—from the trail to that well-earned post-ride beer.
