Weight per pair Pedal recommendation: PD-R9100 360° WRAP-AROUND UPPER The 360° wrap-around upper shoe wraps the foot like a second skin, providing a superior fit, unparalleled stability and lightweight performance for all riders. SEAMLESS MIDSOLE CONSTRUCTION A midsole in contact with the leather upper helps keep feet closer to the sole. This reduces sole height and optimizes fit, keeping the foot securely in place while pedaling. It also reduces power loss and risk of defect.
