The Shimano RC3 Men's Road Shoes feature a fit-engineered lacing pattern and the BOA® Fit System for balanced forefoot comfort. The seamless midsole and upper construction provide exceptional fit and stability, while the low stack height midsole enhances power transfer efficiency. The surround wrapping upper structure offers a glove-like feel, minimizing overlap and maximizing comfort. Made with 36% recycled mesh, the shoes have a perforated synthetic leather composite upper for breathability and a lightweight glass fiber reinforced nylon sole for efficient power transfer.
