Union All Weather Flat MTB Shoe

What Our Gearhead® Experts Are Saying:

"Between the grippy rubber and waterproof design, these shoes have become my go-to for foul-weather riding. The dial makes them super easy to dial in mid-ride, and I can’t overstate how nice the D3O insole feels after rough descents."

For riders who don't shy away from the elements, the Union All Weather Flat MTB Shoes offer a durable, waterproof solution engineered for aggressive trail performance. A fully sealed upper and extended collar block out water, dirt, and trail debris, while the BOA® Fit System delivers instant, micro-adjustable security even when hands are cold or wet.

Internally, a D3O insole cushions impacts and reduces fatigue over long descents or chatter-heavy sections, and a tuned midsole balances stiffness for efficient power transfer with enough compliance for off-bike comfort. The outsole features Fox’s proprietary Ultratac™ rubber compound, which delivers high-friction pedal grip and rugged durability on rocky, muddy hike-a-bike sections. Built to thrive in the sloppiest seasons, the Union All Weather Flat is a must for riders who chase singletrack year-round.
