Studded footwear
First Claim
1. A stud for use with an article of studded footwear having a receptacle with a multi-start screw-threaded socket, having a spigot with a multi-start screw thread complementary to the screw thread of the socket, such that rotary insertion of the spigot into the socket secures the stud in the receptacle, characterized in that the spigot has one component of a helical key and complementary keyway of which the other component is provided on the receptacle, the helical key and keyway defining the initial position of the spigot relative to the receptacle at the start of the insertion of the spigot into the socket, wherein said initial position is the only rotational position in which the screw-threaded spigot and the screw threaded socket can start to engage.

Abstract
A shoe stud for a sports shoe has a ground-engaging part and a multi-start threaded spigot for engagement in a complementary socket on a receptacle secured in the shoe sole or heel. The stud and receptacle also have a locking device which inter-engages when the spigot is fully inserted into the socket, to resist unscrewing. In order to ensure that the stud takes up a precise position relative to the receptacle, which may be needed if the stud is not rotationally symmetrical, the stud and receptacle have means to determine the initial position of the stud relative to the receptacle, and means to determine the final position of the stud relative to the receptacle. Determination of the initial position may be provided by a thread and complementary groove of the screw-thread connection which are of different dimensions from the others.

- 9. A receptacle for incorporation in an article of studded footwear having a multi-start screw-threaded socket adapted to receive a spigot of a shoe stud, the spigot having a multi-start screw thread complementary to the screw thread of the socket, such that rotary insertion of the spigot into the socket secures the stud in the receptacle, characterized in that the receptacle has one component of a helical key and complementary keyway of which the other component is provided on the spigot, the helical key and keyway defining the initial position of the spigot relative to the receptacle at the start of the insertion of the spigot into the socket, wherein the initial position is the only rotational position in which the screw-threaded spigot and the screw threaded socket can start to engage.

16. A removable stud for a shoe comprising:
a spike structure for engaging the ground, and an attachment structure for removably attaching the spike structure to a socket in a shoe, the socket including one component of a helical key and complementary keyway of which the other component is provided on the spike attachment structure, the helical key and keyway defining the initial position of the spigot relative to the receptacle at the start of the insertion of the spigot into the socket, wherein the initial position is the only rotational position in which the screw-threaded spigot and the screw threaded socket can start to engage. - View Dependent Claims (17, 18, 19)
