The Shimano RX-8 Clipless Shoe marries the top performance features of Shimanos premium mountain bike and road racing footwear in a shoe that balances pedaling performance and off-the-bike capability. The result is a lightweight, stiff, walkable shoe that is ideal for gravel racers, gran fondo riders, and weekend warriors. Comfort is critical for ultra-endurance gravel racing events and the RX-8 delivers a glove-like fit. The shoe utilizes a one-piece Surround Structure synthetic upper with perforated venting and secures the foot with a single Boa IP1 dual micro adjustment dial. Weight is reduced by utilizing a Velcro strap at the front of the shoe.
