The Nordica Firearrow F3 Ski Boots are a completely new design focused on the demands by modern skiers who create greater lateral forces, increase inclination and ski at faster speeds. The Fire Arrow boots address these new demand with enhance lateral precision, progressive forward flex creating easier ankle articulation and a 45 degree closure system for maximum heel retention. They also offer more forefoot comfort, progressive flex, tongue rebound, and the easiest entry and exit regardless of temperature. Nordica's EDT Technology gives the boot more strength to resist twisting, giving you more power to turn your skis easier. With a new design, comes a new way to measure. Instead of just one number representing the flex, Nordica has begun adopting the Dynamic Performance Code to measure three performance parameters. Stiffness (1-20) measures the amount of force needed to bend the boot forward. Progression (1-3) is how much stiffer the boot gets as it is flexed forward. Rebound (M=slow, H=medium, E=fastest) is how quickly the boot returns to neutral from its deepest flex. The stiffer the boot, the higher the transmission of power to the ski. The F3 has a flex rating of 14.0. The bigger progression, the stiffer the boot behaves through the forward flex allowing the most precise load transmission of the ski. The F3 has a medium progression rating of 2. The higher the rate of rebound the faster the boot returns, enabling a quicker turn and ski edge change. The F3 also has a medium rebound rating of H.
