Abstract: An arrangement for treating the running surfaces of skis, particularly for grinding the running coating and the steel edges of skis. The arrangement includes a rotating grinding member in the form of a grindstone or grinding belt. A rectilinear guide means extends parallel to the plane of rotation of the grinding member and is arranged above the grinding member. The guide means is capable of receiving and longitudinally displacing a support rail. The guide means is arranged on a support member which is vertically adjustable relative to the grinding member and is pivotable in the plane of the longitudinal extension of the guide means. Brackets are mounted on the underside of the support rail. The brackets are spaced apart from each other in longitudinal direction of the support rail. Holders for holding a ski to be treated are arranged on the brackets.

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.
