Shimano RC502 Road Cycling Shoes A mid-range road cycling shoe that blends performance with comfort and support, the Shimano RC502s borrow technology from the top-end S-PHYRE models. The nylon sole is reinforced with carbon, making it stiff and efficient, while a low stack height further improves power transfer and stabilises the foot. A combination of mesh, TPU and synthetic leather is used for the upper, and a new pattern brings enhanced breathability and fit, wrapping the foot for a customised feel. A BOA dial and velcro strap take care of closure, allowing plenty of room for adjustments.
