Dynamic Performance Code: The DPC measures the three performance parameters. STIFFNESS, PROGRESSION, REBOUND. Stiffness measures the amount of force needed to bend the boot forward. The higher the boot stiffness, the higher the transmission of power to the ski. Progression - progression represents the increase in stiffness as the boot is flexed forward from the neutral position to deepest flex point. The bigger progression, the stiffer the boot behaves through the forward flex allowing the most precise load transmission of the ski. Rebound - Rebound measures the rate at which the boot returns to the neutral upright position from the deepest flexing point. The higher the rate of rebound the faster the boot returns, enabling a quicker turn and ski edge change.
