Shimano RC503 Road Shoes

Shimano’s RC503 brings race-day tech to everyday riders—without the premium price tag. A supple, wrap-around synthetic upper fuses seamlessly to a carbon-reinforced midsole, creating a 360° fit that locks your foot in place for efficient power transfer. The low-stack sole (stiffness index 8) sits closer to the pedal axle for faster acceleration, while the BOA® L6C dial and offset strap fine-tune tension in seconds—even on the move. Breathable TPU mesh panels keep feet cool on long summer rides, and the durable TPU-covered heel pad gives sure-footed café stops. Available in Black, White or Cyber Blue—in standard EU 38-48 plus wide sizes 40-48—and fully SPD-SL compatible.
