Sidecut radius
The radius of the curved line that forms the sidecut of the skis. Such sidecuts are typical for mountain models — they are necessary for successful cornering at speed. At the same time, the smaller the sidecut radius, the more pronounced its curvature, the greater the difference in width between the tip/tail and the waist, and the higher the steering (smaller turning radius). In turn, for "high-speed" skis (for example, for giant slalom), the radius of curvature is usually small.
Tip width
The greatest width of the skis in the front.
The ratio of the width of the "tip", "waist" and "tail" allows you to estimate the radius of the side cutout (see above) — there is a special formula for this. In general, wider skis (with the same length) are more passable and less “fast” than narrow ones — they fall into the snow less, but they also go forward worse.
Waist width
The smallest width of the skis in the middle part; usually, in the binding area.
The ratio of the width of the "tip", "waist" and "tail" allows you to estimate the radius of the side cutout (see above) — there is a special formula for this. In general, wider skis (with the same length) are more suited for cross skiing and less “fast” than narrow ones — they fall into the snow less, but they also go forward worse.
Tail width
The greatest width of the skis in the tail.
The ratio of the width of the "tip", "waist" and "tail" allows you to estimate the radius of the side sidecut (see above) — there is a special formula for this. In general, wider skis (with the same length) are more designed for cross-country skiing and less “fast” than narrow ones — they fall into the snow less, but they also go worse forward.
