The Giro Chamber Shoe offers 'cross and downhill racers all the power benefits of a stiff, clipped in shoe while still maintaining functionality for those moments when the shoe isn't locked to the pedal. The Chamber's stiff insole eliminates pressure points, and its Vibram outsole provides traction on the pedals when the cleat isn't locked in. This shoe is designed to keep a low profile over the pedal for efficient pedaling, and it includes a heel cup and bootie retention system for a comfy and secure fit that's free of heel slippage. Giro also includes Poron XRD in the heel cup to help absorb impacts and a rubber reinforced toe box for durability. The Giro Chamber Shoe has a breathable upper to keep your feet happy and dry and a hook and loop strap to keep laces safely away from the drivetrain.
