Base - the bottom surface of the ski that aids in gliding. Camber - the curvature of the ski's base that helps distribute the skier's weight over the length of the ski. Cord length - the overall length of the ski. Dampening - the reduction of ski vibration or "chatter". Edge - the metal surface on the ski that aids in snow holding. Flex/Torsion Ratio - the relationship of a ski's longitudinal flex to its torsional flex. Softer longitudinal flex and stiffer torsional flex provide more stability. Length - the measurement in centimeters from the ski's tip to its tail. Profile - the outline of the ski when viewed from the top or bottom. Running surface - the total area of the ski that contacts the snow's surface. Side cut - the "hourglass" shape a ski has as a result of a wide tip and tail and a narrow waist. Swing weight - the rotational mass of the ski--a lower swing weight allows quicker turn initiation. Tail - the rearward most part of the ski. Tip - The forward most part of the ski. Torsional flex - the measured amount in which the ski flexes along its width or the amount in which the ski "twists". Weight - the physical mass of the ski.
