The Fox Head Union BOA is a clipless mountain bike shoe built around fine fit adjustment and a supportive connection to the pedals. Two BOA Li2 dials let you make small tension changes during a ride, while high and low arch-support options give you a choice of support beneath your foot.
A moulded internal plate supports your foot as you pedal. Ultratac rubber and the surrounding tread provide grip when a section needs walking, and D3O cushioning helps reduce vibration underfoot. The two-bolt cleat mount connects the shoe to a compatible mountain bike pedal system.
The welded TPU and ripstop upper is built for regular trail use. A moulded toe cap reinforces the front of the shoe against rock strikes, combining practical protection with the adjustable closure.
Two BOA Li2 dials give you small, controlled tension adjustments without retying laces. It's a useful way to refine the fit during a ride, with the upper held securely around your foot.
Pedalling support with grip off the bike
The internal stiffening plate supports power transfer through the two-bolt cleat interface. Ultratac rubber around the sole adds grip for the parts of a ride you tackle on foot, balancing pedal efficiency with off-bike use.
Toe protection for rocky trails
The moulded toe cap helps protect the front of your foot from rock strikes. Behind it, a welded TPU and ripstop upper provides a durable construction for repeated trail riding.
Choose the support beneath your foot
High and low arch-support options let you adjust the support beneath your foot, alongside the BOA tension adjustment across the upper. It gives you a useful choice when setting up how the shoe fits and supports your foot.
