SHIMANO SH-RC903 Road Cycling Shoes, men’s, white, 45.5

The Shimano SH-RC903 are road racing shoes designed for maximum power transfer and performance. They use DYNALAST technology, which optimises foot position for more efficient pedalling. The micro-perforated synthetic leather upper ensures breathability, while the 360° Surround Wrapping Upper construction securely envelops the foot. You can precisely adjust the fit using two BOA Li2 dials, which allow for fine adjustments even while riding.

Precise fit and foot stability

The shoe's upper uses a 360° Surround construction that wraps the foot from all sides, ensuring a secure fit without any unwanted movement. Precise tightening is handled by two low-profile BOA Li2 dials, which allow for fine adjustments in both directions. For stability during maximum output, such as during sprints, the heel is equipped with a special anti-twist stabilising heel cup to keep the foot in place.

Carbon sole and DYNALAST technology

The foundation of the shoe is the Carbon XC sole with a stiffness index of 12, ensuring efficient energy transfer to the pedals. The construction integrates a seamless midsole, which reduces the overall stack height and improves foot stability. Shimano DYNALAST technology holds the foot in an ergonomically optimal position, reducing tension in the arch and promoting a smoother pedalling motion. The synthetic leather upper is breathable thanks to micro-perforations.
