ABSTRACT:
A multilayer ski with a sandwich type construction includes a core, a cover layer on one side of the core, a running base layer on the other side of the core and at least one web positioned between the core and one of the cover layer and the running layer. One of the web or the core is divided across the width of the ski into a plurality of parts with each part having a different shear modulus. Longitudinally extending parts of the ski on opposite sides of an imaginary plane extending perpendicularly to the running base layer in the long direction of the ski and positioned at least close to the central longitudinal axis of the ski, have different torsional strengths.
