The Shimano S-Phyre RX910 Men’s Gravel Cycling Shoes redefine performance for gravel racing and endurance riding. Featuring Shimano’s new Pontoon outsole system, dual BOA® Li2 dials, and a full carbon composite sole, these shoes deliver pro-level stiffness, comfort, and traction for long days on mixed terrain.
Key Features
- New Pontoon outsole system: Innovative TPU “pontoon” extensions around the cleat interface enhance walking stability, reduce cleat wear, and add grip on loose or uneven terrain—without compromising pedaling efficiency.
- Dual BOA® Li2 dials: Provide precise, micro-adjustable control for a perfectly secure, performance-focused fit.
- 360° Surround Upper construction: Wraps the foot evenly for improved comfort, stability, and efficient power transfer.
- Carbon composite sole: Ultra-stiff platform maximizes energy transfer during sprints and climbs while keeping weight low.
- Gravel-optimized outsole: Lightweight TPU tread design improves traction and durability for off-bike sections.
- Perforated synthetic leather upper: Offers lightweight durability, ventilation, and a premium fit that adapts to foot shape.
- Integrated heel cup: Locks the heel in place for improved stability and pedaling efficiency.
- SPD cleat compatibility: Works with all 2-bolt SPD pedal systems used for gravel, MTB, or mixed-surface riding.
