a mold (29) together with an elongated piece (31) of foamable gum substance, and the
mold (29) is heated so as to internally produce foam pressing the components (25/32)
to the internal surface of the other components (21/22/23a/23b) providing the outer
configuration of the ski, thereby economically fabricating the ski without a void.
