FOX UNION BOA FLAT CYCLING SHOES

Fox Union BOA® Flat MTB Shoes

A new generation of MTB shoes that elevates your ride to the next level. The Fox Union BOA® flat shoes are engineered for maximum control, grip, and a precise fit—for trail, all-mountain, and everything in between.

The dual BOA® Li2 system allows micro-adjustments on the fly, while the new upper construction (TPU + ripstop) delivers increased durability, breathability, and a better feel on foot.

A fit you can dial in to the millimeter

The dual BOA® Li2 system enables quick, precise adjustments—even while riding. The result is a locked-in fit and better power transfer to the pedals.

Grip that keeps you on the pedals

The Ultratac™ rubber outsole with an optimized pattern provides superior traction on flat pedals and outstanding durability—for total control on every trail.

Control + comfort = performance

The low-profile EVA midsole enhances pedal feel, while the internal reinforcement plate optimizes power transfer without compromising walking comfort.

Protection you actually need

The reinforced toe cap protects against rock strikes, while the D3O® insert in the sole absorbs vibrations and increases comfort on longer rides.
