These shoes combine the walkability of the WR model with a stiff carbon fiber sole for increased performance.
From the manufacturer
Use either 2 Bolt or 3 Bolt cleats. The WRX (Walkable Road Xchange) Granfondos blend the performance qualities of true road shoes with the practicality of a usable sole for off the saddle.
The stiff carbon sole has removable bolt-on rubber lugs that pad out around the cleat, making it recessed. They make standing and short walks safer and easier. The system works best with two-bolt cleats, as you need to remove the side rubber pads to place any three-bolt cleats.
