About this product
The Shimano S-Phyre RC903 PWR Wide shoes are designed for cyclists with wider feet who want maximum power transfer and efficiency. This makes them as good a choice for track riding as the road. Featuring a reinforced surround-wrapping upper with an integrated padded tongue, these shoes deliver a secure, glove-like fit for enhanced rigidity and stability. The ultra-stiff carbon sole paired with a low-stack-height midsole ensures optimal pedaling efficiency, making them Shimano's most efficient cycling shoes yet. Designed for powerful sprinters, track racers, and time trialists, the RC903 PWR shoes also incorporate a 360-degree upper. It is reinforced with a thin, pliable plastic layer to maintain comfort while delivering the stiffness needed for high-power output.
Built for race-winning performance, the RC903 PWR shoes include advanced features like a BOA Li2 dial closure system with power boost cable routing for evenly distributed tension and a secure fit. An anti-twist heel cup enhances foot stability during intense efforts, while perforations in the upper increase breathability and accommodate a wider foot. A new optical coating on the heel and outsole adds a dazzling finish, ensuring these shoes look as fast as they perform. From sprints to time trials, the S-Phyre RC903 PWR Wide provides unmatched security, comfort, and power transfer for riders chasing peak performance.
