The all-new Fox Union flat shoes are ready to take your mountain bike adventures to a new and more confident level. The flat version of the Fox Union mountain bike boot sticks confidently to your platform pedals, and if you take a corner with too much pepper, it allows you to easily stick your foot out and steer the boat. Built with rugged features, including a molded cap design to protect against rock bumps, the Fox Union Flat can handle the rigors of trail riding with ease.
Low-profile, custom-tuned EVA midsole with a lightweight, precision cut design increases grip and pedal feel, giving you more comfort while shredding. Power to the pedals is optimized by the care of the contoured inner reinforcement plate, but it's not stiffness at the expense of off-the-bike comfort. If you had to pedal your bike around that downed tree, you're good to go.
The outsole is designed using Ultratac™ rubber compound, and the engineered tread pattern provides best-in-class grip and durability. Versatile and with understated style, the Fox Union Flat MTB shoes were born to rock and easily transition from sweet single track to your post-ride beer.
- The Ultratac™ outsole balances grip and durability
- Custom hex-shaped lugs connect with flat pedals for bike control
- The spacing of lugs on the toe and heel is ideal for hike-and-bike sections
- One-piece upper for a consistent and precise fit
- Welded weatherproof construction protects from the elements
- Inner molded heel locks in the heel for a premium non-slip fit.
- Tuned EVA midsole balances cushioning for all-day riding comfort and cycling efficiency.
- High-density textured print in high-wear areas for improved durability
- Lace-up closure with front elastic band and lace-up system
