Nordica Fire Arrow F4 Boot 2012

The Fire Arrow boot is a completely new design built to meet the needs of modern skiers who create greater lateral forces, increase inclination and ski at faster speeds. The Fire Arrow boots address these new demand with an entirely new shell design to enhance lateral precision, progressive forward flex creating easier ankle articulation and a 45 degree closure system for maximum heel retention. Stiffness: 13.0 (Progressive Flex up to 100), Progression: 2, Rebound: H, Last:100

Features

• 45 Degree Retention
  Maximum heel retention, forefoot comfort, easiest entry and exit regardless of temperature
• Dynamic Performance Code
  It measures the tree 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.
