The Fire Arrow F4 W is an advanced ski boot designed to rip up the hard pack like you have never done before. A new shell design started with the lower cuff being taller, for more lateral precision, and an increased range of motion from side to side. Stiffness measures the amount of force needed to bend the boot forward. Progression represents the increase in stiffness as the boot is flexed forward from the neutral position to the deepest flex point. The bigger the progression, the stiffer the boot behaves through the forward flex allowing faster load transmission of the ski. Rebound measures the rate at which the boot returns the neutral upright position from the deepest flexing point. The higher the rate of rebound the faster the boot returns, enabling a quicker turn. A 45 degree instep retention buckle keeps your foot locked in without deforming the shape of the boot or your foot. The three piece shell design is easy to enter and exit. The Fire Arrow F4 W will change the way you ski, and the development of ski boots in the future.
