Shimano SH-RX600 Gravel Shoes Ride Far. Walk Freely. Gravel riding demands a shoe that pulls double duty: stiff enough to transfer power on long climbs, walkable enough to handle hike-a-bike without making you miserable. The SH-RX600 hits that balance with a carbon-reinforced sole rated 8 out of 12 on Shimano's stiffness scale, so you get efficient pedaling without sacrificing mobility when you step off the bike. The perforated synthetic leather upper with mesh insert keeps airflow moving on hard efforts.
