Abstract: A football shoe for use in preventing leg injuries is provided. This shoe includes a vertical portion preferably having eyelets for a shoelace, a sole having a lower surface and a heel portion, and a plurality of cleats. Each cleat having or using a break-away means for breaking the cleat away from the sole of the shoe such as by using either a break-away portion or an adhesive layer on the top portion of each cleat which is bonded to the sole's lower surface that is used to hold each cleat on the sole of the shoe. Both the adhesive layer and the break-away portion or piece have a preselected failure shear force the occurrence of which causes a separation of each cleat from the sole thereby avoiding leg injuries.

Abstract: A spike shoe construction including a socket carrying ribbed insert mounted on and spaced from an outer sole with each socket carrying reusable lock means for locking spikes installed in the socket. Each spike in turn carries a lock means which is non-reusable in that it is so distorted or broken when removed to render it inoperative.

Abstract: It is known to provide studs having externally screw-threaded spigots which are screwed into sockets provided in the soles of articles of footwear. In use, lateral forces applied to the ground-engaging portion of such a stud tend to damage the associated socket, particularly if the socket is made of a plastics material. To resist radially outward expansion of the socket the invention provides retaining means spaced outwards from the spigot. The retaining means may consist of a retaining ring with a flared bearing surface. The presence of the retaining means may render a split socket usable; also it may assist in preventing an otherwise loose stud becoming inadvertently unscrewed.
