The next generation of skiers deserves boots capable of meeting their needs—and helping them unleash their potential. Guided by this belief, the Promachine J90 offers pro-level performance in a boot that caters to experienced junior skiers. Thanks to a low volume design, it ensures developing skiers are paired with a last that truly aligns with their foot size. For a refined fit that enhances performance and comfort, the boot’s liner and shell can be fully customized. And for additional warmth, the liner sports Primaloft® insulation. With unparalleled response and precision, the Promachine J90 sets a new standard in boots designed for young, committed skiers.
