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

Removable shoe spike lockable to configured sole plate

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.

Studs for footwear

Stud for an article of footwear

A stud for a football boot is moulded in two parts. An attachment portion (1;25) moulded in a hard and inflexible material, such as an acetal resin, comprises an externally screw-threaded spigot (3;27) and a body providing a collar (7;29) a flange (5;30) and a central stiffening support. The stiffening support comprises a hub (8;37) supported by spokes (11;38) extending radially from the hub to the collar. A boss (2;26) of the stud is moulded on to the attachment portion and is of a tough but more resilient material, such as a polyurethane. The boss-forming material flows through apertures between the spokes to join up and form a ring (22) or plug (43) which causes the boss to become interlocked with the attachment portion.

Studs for articles of footwear

An insert for an article of footwear is made as a unitary moulding of a flexible plastics material. It comprises a plurality of internally screw-threaded sockets, for receiving externally screw-threaded spigots on ground-engaging studs, and a support interconnecting the sockets. The support may be of laminar form and may be perforate or imperforate. Each socket may be closed at its upper end. At least one of the bearing surfaces of the internal screw-thread in each socket may be shaped so that in a cross-section containing the axis of the screw-thread the bearing surface appears as a straight line at least substantially normal to the axis. The insert may be incorporated in a sole or heel that is moulded around it or may be secured between the layers of a laminated sole or heel.

Studded footwear

A stud for releasable attachment to an article of footwear, particularly for use in games and sports, comprises a support made of plastics material such as glass-filled nylon and a metal pin element. The support has an externally screw-threaded sleeve for engagement with a socket in an article of footwear and an outwardly directed flange for engagement with the lower end of the socket or with the sole of the article of footwear. The pin element comprises a stem and a ground-engaging head which may be blunt or spike-shaped. In assembly the stem is inserted into the sleeve and is then deformed as by riveting to secure the support and the pin element together.

Studs for footwear and method of making same

It is known for sports shoes, particularly golf shoes, to have carriers anchored in their soles for receiving replaceable studs provided with screw-threaded connecting portions. The invention provides a carrier of plastics material having an internally-threaded tubular body open at at least its lower end. The sole is moulded around the preformed carrier. The carrier has retaining formations to anchor it in the sole. The retaining formations comprise outwardly directed fins. That part of each fin adjacent to the body extends lengthwise, while the outer parts are less extensive and are interconnected by integral linking means, such as an annulus. The body portion extends beyond the linking means. In use the sole material envelopes the fins and the linking means.
