The Shimano RC703 Cycling Shoe offers a dialed-in fit ready to take us to the next level, helping us reach our goals of leading the pack and standing at the top of the podium. Using the same fit technology found in the S-PHYRE shoe, this shoe provides the same comfort, efficient power transfer, and breathability as the pro-level shoes. The synthetic leather upper construction features strategically placed perforations to increase ventilation, while the carbon fiber outsole provides stability and ensures we waste no watts in our pedal stroke. For a personalized fit, we simply twist the dual micro-adjustable BOA L6Z dials and adjust the Power Zone lace guides.
