With an emphasis on warmth and comfort, the Speedmachine J 1 helps children fall in love with skiing. Its three-piece design makes it especially easy to put on and take off. And, by providing significant support, it positions children in a neutral stance that enhances control and stability. To keep feet warm, dry, and comfortable, the boot features a plush, insulated liner. Rather than an afterthought, the Speedmachine J 1 is carefully designed to inspire confidence and help children progress.
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.
