<p>A stud for a football boot is moulded in two parts. An attachment portion (1;25) moulded in a hard an 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.</p> |
