The Shimano RC5 road shoe will give you top performance every time you ride. Imbued with the S-Phyre DNA, they feature a mesh/TPU and synthetic leather upper for a comfortable fit and light weight. The wrap-around upper structure reduces overlap, offering a glove-like fit. The integrated seamless midsole and upper construction allow for a new level of fit, stability and performance while remaining lightweight. The RC5s close with a BOA L6 knob on the instep strap, quickly and comfortably securing a wide range of foot shapes. Carbon fiber reinforced nylon midsole improves power transfer. The low profile midsole helps stabilize the foot and maximize power transfer and efficiency.
