Abstract: A shoe stud and receptacle, the shoe stud including a ground-engaging part and the two components are adapted to be secured together by a multi-start threaded connection comprising a screw-threaded spigot on one of the two components adapted to be inserted with rotation into a screw-threaded socket on the other component, and a locking means of the components which is arranged to become interengaged to resist unscrewing of the assembly, the locking means comprising a primary locking means and at least one secondary locking member, the primary locking means comprising a ring of posts extending axially from one of the components and a ring of teeth on the other component, the posts engaging between the teeth, and wherein the or each secondary locking member is adapted to engage with a post to maintain the interengagement of the primary locking means.

Abstract: A cleat for a shoe has an annular array of different types of angularly spaced traction elements disposed about and depending from a hub periphery. The array includes plural types of flexible traction elements and plural types inflexible traction elements interleaved within the array. The dynamic elements are longer than the static elements and are of two different lengths. The static elements have two different configurations. The flexible elements are sufficiently close to adjacent inflexible elements to permit grass to be trapped therebetween when the flexible elements are flexed.
