The next generation of skiers deserves boots capable of meeting their needs—and helping them unleash their potential. Guided by this belief, the Promachine J 90 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 J 90 sets a new standard in boots designed for young, committed skiers.
Understanding boot and binding compatibility can be complicated. Use the following information to help narrow your search, and contact us with any questions:
ISO 5355 - Alpine
ISO 5355 refers to most ski boots with alpine soles and is further broken out by Adult Alpine (Type A), and Junior or Children Alpine (Type C) ski boots. ISO 5355 soles work with alpine bindings, WTR bindings, and GripWalk bindings.
ISO 9523 - Touring
ISO 9523 refers to most ski boots with touring soles. These soles typically feature some form of rockered profile and/or a rubber compound designed to make walking easier and more comfortable. ISO 9523 touring soles work with WTR bindings, GripWalk bindings, and frame bindings.
WTR is a sole and binding system. On boots, WTR means hard plastic toe and heel pieces and a slightly rockered profile designed to enhance walking comfort. WTR soles work with WTR bindings, ISO 5355 alpine bindings, and in rare cases GripWalk bindings.
GripWalk is another sole and binding system. On boots, GripWalk uses hard plastic soles with a rocker profile designed to enhance walking comfort. GripWalk soles work with GripWalk bindings, ISO 9523 touring bindings, and MNC (Multi-Norm Certified) bindings.
*Both WTR and GripWalk are compatible with some ISO 5355 Alpine soles, but not all.
