Unrivaled speed

- Premium Road Cycling Shoe: S-PHYRE RC903 Women’s is a breathable, high-performance SPD-SL road racing shoe
- Precise Fit: dual low-profile BOA® Li2 dials deliver quick and precise micro-adjustments
- Optimum Stiffness: reduces energy loss and maximizes power transfer
- Anti-twist Heel Cup: stabilizes heel to help manage the intense twisting forces caused by explosive acceleration
- Women’s Sizing: designed with a women’s specific last for a natural, comfortable fit.
- Cleats sold separately

Anti-twist stabilizing structure within the heel cup offers unparalleled stability during explosive sprints. DYNALAST technology secures your foot in place, reducing power loss at the pedal and lessening fatigue during long rides, while the optimized toe-spring section reduces tension in your feet, calves, and hamstrings - so you can go further, faster.

How a shoe fits and feels defines its performance. The S-PHYRE RC903 Women’s takes both to the next level with a 360º surround wrapping upper, a refined toe box fit, and a low-profile crossover lacing pattern with two BOA® Li2 dials for the most precise fit possible.
