Kid skiers are looking very strong these days, and the equipment has a lot to do with it. The Lange RSJ 65 junior ski boots are a fantastic choice for young skiers who are looking for appropriately high-performance in a well-fitting setup. These boots come in sizes from 19.5 to 27.5, with the adult norm starting at the 22 size and up, so take that into account when matching potential boots and bindings. Made with four buckles and a power strap in an overlap design, these boots are anatomically shaped to fit your foot and flex naturally with your ankle. The toe and heel plates are replaceable, and can be switched out because a lot of kids really seem to love shuffling along the plaza bricks for some reason. Kids are hard on gear; we all know that. The 30 mm power strap is able to cinch up the top of the boot with ease, and you can fine-tune the flex of the boot through the power strap. The tongue loop is great for helping kids get their own boots on, and the junior liner is comfortable and warm. There have been a lot of days that have ended too early due to cold feet, and Lange does a great job making and keeping kids comfortable and warm throughout the day. The 65 flex is great for kids about the same weight, depending on size, as the bigger the boot, the higher the cuff, and therefore the stiffer the flex. The number is just a general guide, not a hard and fast weight amount.
