The Shimano S-Phyre RX910 Men’s Wide Gravel Cycling Shoes represent the pinnacle of performance, innovation, and comfort for gravel racing and endurance riding. Designed with Shimano’s new Pontoon outsole technology, dual BOA® Li2 dials, and a carbon composite sole, these shoes deliver unmatched stability, efficiency, and fit for demanding mixed-surface adventures.
Key Features

- Perforated synthetic leather upper: Lightweight, durable, and breathable for long-distance comfort.
- Wide fit version: Adds forefoot volume and toe box space for riders needing extra room without sacrificing support.
