Abstract: A ski binding wherein a cross-country ski boot is attached to a ski by way of an extension portion of an outer sole projecting beyond a forwardly located tip of the ski boot. The extension portion has on its top side a transversely oriented rib-like bulge. A reinforcing insert is arranged in the outer sole of the cross-country ski boot with the insert extending at least from a ball portion of the outer sole into a zone of the rib-like bulge. A fastening arrangement is provided for clampingly engaging the rib-like bulge with the fastening arrangement extending in a claw-like manner over the rib-like bulge so as to clampingly embrace the bulge.

Abstract: A profiled outer sole for shoes, especially sport shoes, made in a mold and consisting of rubber or other material having rubber-elastic properties, which is provided with profiled projections laterally delimiting the tread surface of the outer sole; the profiled projections, in turn, are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections within the bisecting plane thereof.

Abstract: A profiled outer sole for shoes made of a material having rubber-elastic properties with the sole including a tread surface having a front tread end portion, rear tread end portion, a profiled middle area and profiled marginal areas arranged on respective sides of the middle area. The front tread end portion, the rear tread end portion and each of the marginal areas include outer edges adjoining the tread surface to a shell rim of the outer sole with each of the outer edges being rounded with a predetermined radius. The marginal areas define foundation strips having spaced block-shaped profiled projections enclosing box-shaped profiled projections with a number of groove-shaped slots being substantially uniformly distributed along each of the foundation strips.

Abstract: A ski boot which is connected to a ski by means of the tip (projection) of its sole. The tip extends beyond the leg of the boot and the sole essentially comprises rubber or similar synthetic material. The sole is provided with an insert comprising a plate of steel or similar material which extends to the tip of the sole up to the region of the fastening means which connect the ski boot to the ski.
