The Shimano SH-R310 shoe, with heat-moldable Custom-Fit insoles and panels, conforms like a well-made glove to every contour of your foot. Using a heat vacuum process, gaps and pressure points are eliminated, resulting in a stable, rigid, lightweight platform. Asymmetric buckles and offset straps eliminate pressure points, while the deep heel cup stabilizes your foot. Rigid synthetic leather upper incorporates composite honeycomb mesh on the toe box to let the shoe breathe. The lightweight Carbon Fiber Monocoque Outer sole adds strength and rigidity.
