ABSTRACT:
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.
