Fischer upgraded its Vacuum Fit technology, but the basics remain the same: A qualified bootfitter heats up the shell, adjusts the stand position and cools it down with a compression pad so that the entire boot forms to the foot’s shape. The Progressor 13 has a 130 flex and the last size can range from 95 mm to 105 mm. Other features include Fischer’s V-position designed to mimic a natural stance, Ulralon Padding in the liner, an adjustable spoiler and replaceable toe and heel plates.
