Abstract: A threadedly engageable tire stud includes an elongated steel housing having a hexagonal head section and a threaded section of enlarged pitch for securely engaging a tire thread wherein the head section has approximately the same diameter as a major diameter of the threaded section. A longitudinally extended aperture is provided in the hexagonal head section for receiving an elongated carbide pin. The carbide pin is brazed to the elongated steel housing and protrudes out of the head section of the housing for engaging the road surface to improve traction of the tire.

Abstract: Conventional fishing waders are made adaptable for use under a plurality of conditions by utilizing different types of removably attachable spikes and cleats. Additionally, the soles of the waders may be covered with a felt material. The removable spikes are used with sand and gravel surfaces, and the removable metal cleats are best used for swift moving water and slippery rocks. The felt covered soles provide improved wader traction over larger sizes of gravel and rocks.

Abstract: A running shoe is provided for running along a shore line on a beach and consists of heel and toe cleat structures attached to a sole of a waterproof upper that will give increased traction and stability to the shoe.

Abstract: One golf shoe of a pair of golf shoes worn by a golfer is designed to aid the golfer to take a strong, braced stance with his right foot if he is a right-handed golfer or with his left foot if he is a left-handed golfer. This is accomplished by making the spikes on the outer edge or periphery of the shoe longer than the other spikes on the same shoe and on the other shoe. The spikes may also or alternatively be thicker for resistance to penetration into the ground or for added strength. The spikes may also be broader on the bottom or elsewhere to prevent too much penetration into the grass or dirt.

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.
