The Salomon X-Pro R100 is a popular option for the strong intermediate to expert skier looking for performance and great comfort. Salomon's 24mm Oversized Pivot adds a burly connection between the upper cuff and lower shell that adds more power and energy transfer to your skis. The TwinFrame 2 Technology adds reinforcements to the back spine and sole of the shell that adds more power, rebound and reduces torsional twisting for added responsiveness.
