Road shoes give you the power transfer, but they leave you skating across loose surfaces the moment you unclip. Mountain shoes handle the off-bike scrambles, but that extra tread and softer platform costs you watts over long gravel grinds. Shimano built the SH-RX910E S-Phyre Wide to end that compromise. The wide version delivers the same race-level performance as the standard RX910 with additional toe box volume and forefoot space for riders who need room to spread out during all-day efforts.

The Pontoon Cleat System sits at the center of what makes the RX910 different from anything else in the gravel category. Two modular TPU contact blocks mount between your SPD cleat and the shoe, moving with your cleat position to maintain consistent contact with the pedal regardless of where you set up. The result feels remarkably close to a road shoe platform while retaining SPD compatibility and mud-shedding capability. The pontoons are replaceable, so when they wear down from cafe stops and hike-a-bike sections, you swap them out rather than retiring the whole shoe.

Underneath, a carbon-reinforced midsole rates 12 out of 12 on Shimano's stiffness scale, matching their S-Phyre road shoes. The seamless midsole construction reduces stack height to position your foot closer to the pedal spindle. TPU lugs on the outsole provide enough grip for short walks without adding unnecessary bulk, and dual drainage holes evacuate water from creek crossings while pulling cooling air through on dry days. The ventilation works both ways, keeping your feet from overheating during summer rides while letting them dry quickly after unexpected water encounters.... Read More
