The sidecut is determined by 3 measurements: the width of the tip (front of the ski), the waist (middle of ski) and tail (back of ski). The wider the tip, the easier the turn entry. The narrower the waist, the stronger the grip in hard snow. The wider the waist, the more comfortable and stable in different snow conditions. The wider the tail, the better the grip in the turn. The narrower the tail, the better the glide.
