Shimano RC3 Road Cycling Shoes Offering features derived from their premium shoes, the RC3 Road Cycling Shoes from Shimano are a fantastic way to experience the increased comfort and efficiency of a dedicated cycling shoe. The sole unit is drilled to accept 3-bolt road cleats and is made from glass-fibre reinforced nylon for stiffness and the seamless midsole construction keeps the foot closer to the pedal for better power transfer. A single BOA L6 dial operates the closure system, giving quick adjustability and great security, with the wrap-over design of the tongue eliminating any potential for chafing. Good breathability is assured by the use of synthetic leather composite for the upper.
