SHIMANO SH-RC903 Road Cycling Shoes, men’s, white, 43.5

The Shimano SH-RC903 road shoes are a premium racing shoe with a carbon sole and a BOA fastening system. They feature a stiff carbon sole with a stiffness index of 12, which minimises energy loss when pedalling. A 360° surround wrapping upper, combined with two BOA Li2 dials, envelops and secures the foot. The micro-perforated synthetic leather ensures breathability even during intense efforts. Thanks to Shimano DYNALAST technology, the shoes support smoother pedalling.

Maximum power transfer

The foundation of the shoe is a carbon sole with a stiffness index of 12, ensuring efficient power transfer to the pedals. Every watt of your effort is thus used for forward motion. The structure with an integrated seamless midsole reduces the stack height and helps to minimise power loss. This design contributes to a solid and direct connection between the foot and the pedal.

Perfect fit and comfort

The 360° surround wrapping upper structure envelops the foot like a second skin, providing support. The two BOA Li2 dials deliver precise and even tightening, enabling independent micro-adjustments for the instep and forefoot. A micro-perforated synthetic leather upper provides ventilation, keeping your feet dry and comfortable.

Advanced design for higher performance

The shoes use Shimano DYNALAST technology, which promotes smoother pedalling and reduces power loss thanks to an optimised toe-spring section. A specially shaped heel cup stabilises the heel and prevents it from twisting. The durability of the shoe is enhanced by a reinforced toe and anti-scuff protection in the most stressed areas. A replaceable heel pad also contributes to the shoe's longer lifespan.
