A lightweight ski, having excellent flexibility in both vertical and sidewall deflection, yet exhibiting high shear strength, is disclosed. The ski is fabricated using a honeycomb sandwich construction wherein the ribbon or higher shear strength direction of the honeycomb is along the length of the skis. Also, the facings bonded to the top and bottom portions of the honeycomb core comprise a fiber reinforced resin in which the fibers extending along the length of the ski to further enhance a shear strength in that direction. The sidewall of the ski comprises flexible, rubberized material and further, the ski has at least one resilient, flexible metallic running edge, the edge being so constructed that it does not substantially increase the vertical or sidewall stiffness of the ski.
