BOA Li2 Fit System
Precision BOA Li2 dial delivers micro-adjustable, on-the-fly fit customization with a single hand. The low-profile dial sits flush against the shoe to avoid trail hazards, while a secondary hook-and-loop strap across the forefoot provides independent tension control. This dual-zone closure system ensures locked-in security for aggressive pedaling without pressure points during long days in the saddle.

Stealth Marathon Rubber
Legendary Stealth Marathon rubber compound delivers exceptional grip and durability for hike-a-bike sections and unclipped moments. The aggressive "Pillar" tread pattern provides biting traction on loose terrain while maintaining enough surface area for confident scrambling. A specialized rubber that balances the pedaling efficiency of a clipless shoe with the off-bike capability that downcountry riding demands.

Clipless-Optimized Shank
Moderate-stiffness shank (~6.5-7.5/10) delivers the perfect balance of pedaling efficiency and walkability for downcountry riding. The SPD-compatible cleat box integrates seamlessly with 2-bolt clipless pedals, providing a stable platform for power transfer without the harsh rigidity of pure XC race shoes. Designed for riders who pedal hard but still need to walk confidently when the trail gets technical or disappears entirely.
