ABSTRACT:
An athletic or sport shoe, for instance a cross-country skiing shoe or a tennis shoe is disclosed, which has a sole formed of, for instance, polyurethane which is molded at the upper portion of the shoe. In the material of the polyurethane sole there is molded a resilient or spring plate, formed of a suitable metal or plastic. The resilient plate is provided at its front region with flange means serving as support or contact means for the ski binding jaw or the like and holes or perforations for the binding pins or mandrils. The resilient plate extends over essentially the entire length of the shoe sole and is only visible through its flanges at the sole edges. The plate is structured such that at the region of the ball of the foot it is easier to resiliently bend while at the region of the shoe stiffener it is practically hardly resiliently bendable, so that the rolling-off of the foot is possible practically without any hinderance, but the foot is supported laterally and against torsion.
