It also uses a toe-mounted pivot rod and clamp binding, but because the SNS binding uses a different rod position and attachment angle, the SNS and NNN gear is not compatible. The skis At first glance, skis vary widely in the design and intended uses. A closer look, though, reveals that the skis are all remarkably similar. The differences between backcountry touring, Alpine touring and telemark skis deal most with the width, stiffness and length of the skis. The first option to ponder is what kind of base you want.
Waxable skis have a smooth base.
Sticky waxes are applied to the base to prevent the skis from sliding backward while touring. Different waxes are required for various snow conditions. Waxless skis also can achieve traction because a series of small scales line the center section of the ski. When the ski is weighted, the scales press into the snow, preventing backward sliding. Novice skiers often are best served by waxless skis since this simplifies the initial learning process.
