High-performance footwear to enhance your cycling outings. The Fox Union BOA® Flat shoes are designed to take your mountain bike adventures to new levels of safety and control. They offer a custom fit thanks to the dual BOA® Li2 system. We have once again improved our top-of-the-line shoe, this time optimizing its fit and structure, as well as equipping it with a completely new upper (a TPU welded upper with ripstop fabric for an even more durable and breathable shoe).
The Fox Union BOA® flat pedal mountain bike shoes grip flat pedals perfectly. They offer durability features and a shaped toe design to protect against impacts from rocks and gravel.
With a light and precise fit, the low-profile, custom EVA midsole improves grip and sensitivity on the pedals, offering greater comfort while you speed along on your MTB. The power transferred to the pedal is optimized thanks to the internal reinforcement plate. This internal stiffness, however, does not compromise comfort during walking sections.
The outsole is designed using the Ultratac™ rubber compound, with lugs developed to offer top-tier grip and durability. Versatile and understated, the Union BOA® Flat shoes are designed to follow you everywhere, from your single track ride to having a beer with your adventure buddies at the end of the day.
