Shimano RC503 Wide Cycling Shoe - Men's Black, 45.0

What Our Gearhead(R) Experts Are Saying:"I've got wider feet, and finding cycling shoes that fit right is tough. The RC503 Wide nails it-stiff enough for long climbs, roomy enough up front, and the BOA dial makes fit adjustments quick and secure. It feels like a race shoe without the race-shoe pain."Shimano's SH-RC503 Wide Cycling Shoe brings race-level tech to riders who need a little more room. Designed with the same performance features as the standard RC503, this version offers a wider fit through the forefoot without compromising stiffness, comfort, or breathability. A carbon-reinforced nylon midsole (stiffness index 8) ensures efficient power transfer, while the low stack height provides a stable pedaling platform. The laminated mesh and synthetic leather upper wraps the foot for a snug yet breathable fit, and the BOA(R) L6C dial paired with a toe strap allows micro-adjustments on the fly. Built for endurance, training, and spirited rides, the RC503 Wide delivers a perfect blend of comfort and performance.
