Abstract: A sports shoe has an extension to the sole of the shoe projecting rearwardly at the heel end, which extension is springily resilient or can be supported by resilient means on the shoe. A stiffener, for example, a metal plate can be provided to enable the resilience of the extension to be controlled. Also a separate interchangeable spring member can be provided to control the resilience of the projection.

Abstract: An outsole for a sports shoe which enables it to be used for a wider range of different types of ground than is possible with the known outsoles. The sole is provided with profile projections which are each formed by at least two elongate profile bodies which are close together or joined at one end and diverge towards the other end to radiate on one side only of the projection. The projections when stressed counter to the direction of divergence of the profile bodies provide increased support, but provide less support when stressed in the opposite direction. This is particularly true if the profile bodies are constructed of a springily resilient material. By appropriately arranging the profile bodies on the outsole, controlled account can be taken of the requirements in respect of safety against slipping and the sliding characteristics, of the sport shoe.

Abstract: A sports shoe, in particular a tennis shoe, has a sole made of rubber or flexible plastics material and a protective layer of chrome-tanned leather is applied to the running surface of the sole at least in the area which is subject to wear, namely in the area of the point of the shoe, for wear resistance purposes.

Abstract: A sports shoe, particularly for tennis, has a flexible plastics outsole through which extend venting channels which open, on the interior of the shoe, in the region of a wearer's toes and forwardly of the ball of the foot. Channels can be provided through the bottom of the sole to terminate beneath the hollows of the toes and/or through a rim of the sole at the front of the shoe. In addition, an air-permeable toe part and tongue can be provided further to assist air movement through the shoe in use.

Abstract: Gripper element for sports shoes especially for track shoes for use on plastics tracks, in which the element is provided with a body having one or more sharp penetrating surfaces adjacent the free end of the element and one or more support surfaces at a greater angle to the axis of the element, the support surface or surfaces preventing undue penetration of the element into a plastics track. A preferred construction comprises a body having the shape of a half barrel in which are formed a plurality of grooves the depth of the grooves increasing gradually from the free end of the element to a point approximately at the center of the length of the element and then gradually decreasing, the grooves forming the penetrating surfaces and the support surfaces.
