Shimano's flagship racing shoe has been further developed with even more comfort, less weight, and a clearer design. The lightweight, breathable microfiber upper provides a perfect fit and outstanding, consistent comfort. The heel cup, crafted with high-quality materials and anti-torsion stabilization, ensures optimal foot positioning for rapid accelerations. The low-profile cross-lacing elegantly stabilizes the forefoot. The 360° "Surround Wrapping" upper offers a perfect fit for all cyclists. The double recessed BOA Li2 system allows for quick and precise micro-adjustments. The integrated construction of the midsole and seamless upper provides a new level of fit, stability, and lightness.
