Why We Like The Fox Racing Union Lace Mountain Bike Shoe

From the bike park to the enduro course, we need a shoe that delivers uncompromising grip and all-day comfort. The seamless upper features a lace and powerstrap closure to give us a precise, personal fit and a molded toe cap to help defend our toes from painful rock strikes. As we tackle adrenaline-inducing descents, the 2-bolt cleat plate and super grippy Ultratac rubber ensure our feet stay planted securely on the pedals no matter how gnarly the trail gets.


  • Burly MTB shoe built for enduro, freeride, and downhill riding
  • TPU upper provides lightweight durability for technical terrain
  • Hook-and-loop powerstrap lets us lock in an incredibly secure fit
  • Ultratac rubber outsole provides traction on and off the bike
  • EVA midsole helps absorb shock from big drops and quiet trail chatter
  • 2-bolt cleat plate is compatible with most cleat brands
  • High and low arch support options allow for a completely custom fit

Sizing is wildly off

I returned this product before using it
Size Bought:
5' 9"

I ordered a size 9.5, which fox says is 42.5 in euro. According to every other shoe manufacturer, a size 42.5 is closer to a size 8.5, and lo and behold, these fit like an 8.5. Go off of the euro sizing, not the U.S. sizing. And backcountry charges shipping on returns, so I guess I'm going back to boycotting backcountry for both their dumb IP litigation practices and their crappy return policy.
