Description
Nordica’s Speedmachine J4 helps young skiers discover their potential—and a love for skiing. Thanks to an entirely new design, it reduces weight while offering even greater control. To boost confidence and make turning easier, the Speedmachine J4 positions young skiers in a neutral stance that enhances stability. A fourth buckle provides additional support while ensuring the boot is easy to put on and take off. And to maximize warmth and comfort, it features a plush liner. Nordica’s Speedmachine J4 accelerates progression while helping young skiers have an incredible time on the slopes.
