Fox Racing has entered the footwear market for the first time, today releasing the Fox Union Clipless and Flat Pedal Mountain Bike Shoes. Athletes Greg Minnaar, Laurie Greenland, Jackson Goldstone, Nina Hoffmann and Steve Peat have all provided feedback on various iterations of these shoes throughout what has been a two-year development process.
There are three options to choose from; the $249.95 USD Union BOA, the $179.95 Union, and the $149.95 Union Flat. Here’s an overview of the range.

All three models of the Fox Union mountain bike shoes share a one-piece welded upper construction, with a reinforced toe box to protect against rock strikes and some perforations aft thereof to allow the wearer’s toes to breathe. A glass-filled nylon shank stiffens the mid-sole to what Jackson Goldstone reckons offers “the perfect stiffness and support”.

The outsole is made up of Fox’s proprietary Ultratac rubber compound, arranged into hexagonal lugs with chamfered edges. These are said to grip the pins of flat pedals to deliver control, while the broader hexagonal lugs positioned toward the heel are said to be better suited for hike-a-bike sections when you really need to be able to dig into the terrain under foot. The exact formulation of the rubber differs between the flat pedal and clipless options, but Fox aren’t able to share any more detailed information than that.

The Union and Union BOA Clipless options share the same cleat box, with a visual power-control guide to help riders find the best cleat position, and to replicate that position between each shoe in the pair; it offers scope for 33mm of adjustment. Both clipless models will include two pairs of arch height inserts to customize fit for the different clipless pedals on the market.
