The Fire Arrow F3 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. Nordica's EDT Technology gives the boot more strength to resist twisting, giving you more power to turn your skis easier. 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 F3 will change the way you ski, and the development of ski boots in the future.
Great boot with good construction. Super comfy. I have a wide foot (EE-4E in runners) and although it was initially tight, I didn't have any problems with the width on these. Skied a couple of days with them this year and they were super comfy every time. Buckles are super easy to use and completely adjustable.
Overall am quite satisfied with the boot. Initially there was a fit problem as the right boot had what appeared to be a protruding seam in the toe area of the liner. I removed the liner from the boot and was able to correct the problem by manually manipulating the internal toe area of the liner. The boots fit very snug and are quite stiff but manageable. I am still waiting for the plastic outer shell to become more relaxed with continued use. I am sure they will with time as I am very athletic, in excess of 200 pounds, and still ski aggressively even though I am in my early 60's. .
