Now with GripWalk, the Nordica Sportmachine 3 100 Ski Boots just keep getting better. Their roomy 102 mm last provides plenty of space to be comfortable and snug, while an adjustable cuff profile helps change the shape of the upper boot to properly fit your legs. With a new customizable cork liner and a smooth medium flex for intermediate to advanced skiers, you can set out for the blues and conquer the blacks, too.
