The Sidi Wire 3 is a race-bred road shoe engineered for riders who demand maximum power transfer and superior ventilation. The Micro Matrix and Kevlar upper uses zoned densities to optimize airflow and targeted support, while the R2FC full carbon sole with Nexus Bridge (stiffness index 11) delivers efficient, direct power transfer. Firmor X internal reinforcement stabilizes the foot and improves alignment, and the tool-free heel adjuster rounds out a precision fit system built for podium-level performance.
