The Shimano RP1 Road Shoes feature Shimano Dynalast which means the toe-spring section provides optimal support for a smoother, more efficient pedal stroke. A more efficient pedal stroke means less wasted energy so you can finish strong. Dual hook and loop straps ensure you enjoy a quick, easy and reliable way to get the fit just right while a reflective heel cup print keeps you visible if you're on the road after the sun has set. The lightweight glass fibre reinforced carbon sole strikes the perfect balance between stiffness and comfort and is compatible with both 3-hole SPD-SL and 2-hole SPD cleats making them a great choice for indoor cycling classes.
