Fox Union BOA Clipless Shoes

Dual BOA® clipless MTB shoes with Ultratac™ outsole and reinforced construction

The Fox Union BOA Clipless Shoes are designed for riders who want precise fit adjustment, efficient power transfer, and durable protection on technical mountain bike terrain. Built around a secure dual BOA® Li2 system, the shoes allow micro-adjustments in either direction for a consistent, customized fit. The one-piece upper uses welded, weather-resistant construction to maintain structure and comfort in changing trail conditions.

A molded internal heel counter provides a locked-in, slip-free feel, while the reinforced toe and molded toe cap add protection against rock strikes. The EVA midsole is tuned to balance cushioning for long ride comfort with the stiffness needed for efficient pedaling. A lightweight reinforced nylon shank enhances power transfer to the pedals without compromising walkability.

The Ultratac™ rubber outsole delivers dependable grip when off the bike, and the 2-bolt cleat interface is compatible with most major clipless pedal systems. Interchangeable arch supports help riders fine-tune the fit based on foot shape and preference.
