base - / beɪs / -
noun
The underside of a ski or snowboard. Bases are generally made of blends of plastic, most commonly they come in extruded and sintered constructions. Extruded bases are manufactured by melting polyethylene pellets together, sintered bases are manufactured by crushing the pellets together under high pressure. The former is cheaper and requires almost no maintenance however is limited in terms of performance, the latter creates a more porous bases, this allows maximum wax absorption and is more abrasion-resistant.
\\ I wonder what that 'dry skiing' has done to my bases?
