The RC-503 packs pro-level road racing technology into an accessible mid-range shoe. A carbon-reinforced midsole (stiffness index 8) stabilises the foot and transfers more power to the pedals, while power-zone lacing across the toe box locks the foot down and reduces movement during hard efforts.
Fit & Construction
A single BOA® L6C dial gives precise, personalised micro-adjustment on the fly. The full-surround laminated mesh upper blends synthetic leather with breathable TPU mesh, integrating seamlessly with the midsole for a snug fit with no pressure points.
