What Is It
The Shimano SH-RC703 Wide is a performance road cycling shoe designed for riders who want race-level power transfer but need a roomier fit than the standard version. It sits just below Shimano’s top-tier S-Phyre range and is aimed at serious road cyclists, endurance riders, and club racers.
The “Wide” version mainly increases forefoot and overall volume, giving more space for riders with broader feet or those who experience pressure in standard Shimano shoes.

- Surround wrap upper for a snug, glove-like fit
