ABSTRACT:
A shoe upper portion of a ski boot comprises a shell portion enclosing the foot and a tongue portion attached thereto. The tongue portion comprises an instep region and a shin region and a transition region therebetween. A corrugated or undulated wall section having elevations and depressions, i.e. corrugations, is located in the transition region. This wall section is composed of a different type of material than the remainder of the tongue portion and possesses a lower bending stiffness or flexural rigidity than the remainder of the tongue portion. This wall section is non-detachably joined to the remainder of the tongue portion and forms therewith a unitary structure. The larger bending or flexural elasticity of the wall section facilitates bending of the lower leg.
