The Speedmachine J4 helps young skiers discover the mountains—and a passion for skiing. To boost their confidence and control, it positions them in a neutral stance that enhances stability. A fourth buckle provides additional support while still ensuring the boot is easy to put on and easy to take off. And to maximize warmth and comfort, it features a plush liner. Designed to accelerate progression and amplify fun, the Speedmachine J4 helps young skiers—and their families—have an incredible time on the slopes.
