Shimano RX-910 S-PHYRE Gravel Shoes

Our RX910 flagship gravel racing shoes are engineered with cutting-edge technologies to slash weight without sacrificing comfort, durability or performance. They feature our innovative pontoon system that redefines stability by providing a greater connection between the pedal and the shoe. The lightweight carbon composite midsole provides the same pro-level stiffness found in our S-PHYRE road racing shoes, ensuring optimal power transfer for professional performance

Power Meets Purpose: The Pontoon System

At the heart of RX910 is our all-new pontoon cleat system—a breakthrough design that borrows from road and MTB DNA, but is born entirely of gravel.

The pontoons are modular, side-mounted contact blocks that dramatically increase the contact surface between the shoe and pedal. Inspired by early road racing cleat hacks, they are:

Stable: Rock-solid pedal engagement in any cleat position
Adjustable: Pedaling efficiency wherever you set your cleats
Replaceable: Pop in new lugs for a fresh grip before race day
